smbd high CPU utilization

S

SnackMasterX

Hello,

Before getting too deep into the post, please let me know if this seems like something I should file a bug report to address. My primary reason for posting in the forums first is to see if this is either a known issue, a configuration issue, or if others are seeing this issue as well. I've tried searching the forum, bugzilla and google but can't find anything specific for FreeBSD, only some of the variants which don't match my environment close enough to effectively use for troubleshooting.

I'm seeing high CPU utilization when performing file copy operations from my samba share to my windows server, and they always seem to hang at 322kb copied from my samba share to my local system. When the copy hangs I can use top and watch CPU utilization for smbd climb to 100% where it will just sit for a while. If I wait long enough, then I will receive an error from Windows stating there "an unexpected network error has occurred" and smbd will no longer be at 100%. Alternately, if I cancel the copy operation from the windows side then I will watch smbd stay at 100% for some time before eventually returning to normal.

That said, I don't seem to have any issues copying data to the samba share from my Windows Server. I can also access data on the zpool from FreeBSD. I have tried restarting the samba server and even the entire FreeBSD system, but the behavior seems to remain unchanged.

Environment:
FreeBSD 10.2-p9 (only functions are ZFS and SMB/NFS)
Samba 4.3.3
Windows Server 2012 R2 (fully updated)

I've configured samba for AD user authentication which seems to be working flawlessly. I am using a domain user to perform my testing

I used google and a lot of web sites until I finally managed to get this working, so it wouldn't surprise me if this behavior was somehow due to a poorly configured smb4.conf so please let me know if this seems sane or if you can make any recommendations for cleaning this up:

Code: 
[global]

  case sensitive = yes
  unix extensions = no
  nt acl support = yes
  inherit acls = no
  map acl inherit = yes

       netbios name = HOSTNAME
       security = ADS
       workgroup = REALM
       realm = REALM.LOCAL
       socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072
       use sendfile = true

       log file = /var/log/samba43/log.%m
       log level = 1
       max log size = 50

       dedicated keytab file = /etc/krb5.keytab
       kerberos method = secrets and keytab

       idmap config * : backend = tdb
       idmap config * : range = 100000-299999
       idmap config REALM : backend = rid
       idmap config REALM : range = 10000-99999

       winbind separator = +
       winbind use default domain = yes
       winbind enum users  = yes
       winbind enum groups = yes
       winbind use default domain = yes
       winbind refresh tickets = yes



[storage]
   comment = Storage Share
   path = /transition/storage
   available = yes
   browsable = yes
   read only = no
   public = no
   guest ok = no
   writable = yes
   force group = "Domain Users"
   directory mask = 0770
   force directory mode = 0770
   create mask = 0660
   force create mode = 0660

So all of the above stated, any ideas on what I could do next to address the high CPU utilization for smbd when performing copy operations from the samba share to my windows server?
 
Hi,

1. You have said to a local system ? are you are running it in VM ? Or you using different servers ?
2. Please post your /boot/loader.conf and /etc/sysctl.conf.
3. How you use ZFS on your server - controller & configuration for the disks of ZFS. Hope you are not using it on RAID ENABLED controller card.
4. If you don't using RAID enabled card run zpool scrub *YOUR POOL NAME* to be sure that ZFS is okay.
 
Hello,

So the system running ZFS is running on top of ESXi 5.5 and I've allocated plenty of resources to it in anticipation of heavy resource utilization. I am still planning to rebuild the zpool in the near future when I get more disks and some SSDs for L2ARC. Currently it is running 4x 2TB disks in RAID Z, no hardware controller in place.

/boot/loader.conf
Code: 
geom_mirror_load="YES"
kern.geom.label.gptid.enable="0"
zfs_load="YES"

/etc/sysctl.conf
Code: 
# $FreeBSD: releng/10.2/etc/sysctl.conf 112200 2003-03-13 18:43:50Z mux $
#
#  This file is read when going to multi-user and its contents piped thru
#  ``sysctl'' to adjust kernel values.  ``man 5 sysctl.conf'' for details.
#

# Uncomment this to prevent users from seeing information about processes that
# are being run under another UID.
#security.bsd.see_other_uids=0

So I didn't think about it until now, but I did a ZFS RAID 1 for the root filesystem, although it doesn't have dedup/compression enabled like my zpool I created. I do have a scrub running although since this was a brand new zpool, I imagine that will come back clean.

Since I can move data around locally on the FreeBSD box, should I create an additional hard disk, format with ext4 and move data to that and see if the windows host can read data? Normally I wouldn't consider the filesystem being a possible cause for something not working but I've seen bugs which only seem to happen when compression is enabled on ZFS, though I don't believe my version is impacted.

Let me know if you need anything else from me, thanks!
 
Hi,

Thanks for posting config files. I think high CPU usage is coming from your design of this server (ESXi). As you have said above on one of zpools you are using deduplication - it's very hungry for resources. I can say more - ZFS is designed to run on clear hardware, not in VM environment. If it's coming for a great file server with a plenty of storage space with deduplication option turned on - bet it must be only to be run on CLEAR hardware, not in VM.

BTW, how many GB of RAM you have aligned per 1 TB for storage? Additionally can you tell me how is your SWAP is used at this moment?
 
So I've dedicated 4 cores on this ESXi box to the VM along with 32GB of RAM, all reserved. Right now I've only got about 6TB of storage so cutting it close on RAM.

That said, I did move a small file (around 500kb) to the root volume which is also ZFS but no dedup/compression enabled and experienced the same issue. The issue is also specific to samba, not ZFS.

Since it sounds like ZFS is strongly suspected of being the problem, I'm going to create a virtual disk with ext4 to test this. If ZFS is the problem, then I should have no problems copying the data off the ext4 partition. If ZFS is not the problem, I suspect the symptoms will remain unchanged and the file copy will hang at 322kb.

I'll post an update later today.
 
So I'll start with this, I'm a newbie to FreeBSD.

Turns out ext4 was not really an option, so I created a UFS partition following these steps and moved my file over to that and attempted to perform the same steps as mentioned earlier with no change in results. The copy operation still hangs at 322kb transferred and smbd still spikes to 100% before eventually dying.

Any idea what else I can try?

Thanks!
 
Hi again,

Seems the problem not with the filesystems. I bet it's coming from ESXi. BTW, did you installed VMWare tools or how it's called?
 
Why do you think this is a VM issue vs a samba issue? Samba seems to be the only thing that's broken. Are there any logs I can try checking?

I find it highly unlikely that FreeBSD running in a VM would break samba and only samba, if anything it should just be slow because it's not on dedicated hardware. That aside, we aren't dealing with any kind of driver issue here.
 
Hi again, did you tried to install VMWare tools for FreeBSD ? I am not sure, but maybe it needs some drivers to be installed to work correctly...

Addition: VM or net/samba43 - which one is generating a problem there is very hard to say - you are using it in virtual environment. But I may say you only one thing - if you want to do a good working file server with ZFS and add an deduplication you must surelly do it on real hardware, bad idea to do it in virtual environment.
 
I'm sorry but I just can't accept that FreeBSD running in a VM is the root cause for this specific issue.

VMWare ESXi is used widely in the industry and I've never seen this type of issue, just because it was running in a VM.

I understand that running what I'm doing in a VM has performance implications, but I'm not seeing a performance problem, I'm seeing bug behavior. I also know quite a few people who are doing exactly what I'm doing on less powerful hardware, so I doubt it's an issue of being starved for performance.

Lets focus on addressing this from a samba standpoint and take a look at some logs instead of blaming other products for samba not working.
 
Hi,

I never told you that FreeBSD can't be run in VM. I have a lot of virtualized servers under FreeBSD (most of them for webhosting, monitoring, mail things), but none of them using Samba, just because file server that's an specific task and if you want ZFS - it's more than specific task. Noone virtualizing it. Just because if anything going wrong - noone will be able to help you - too complicated.

Okay, please answer all those questions and mask away your ip's (if they are public, don't mask local ones).

1. Did you installed VMWare Tools ?
2. Post your full dmesg output (reboot system and get an output)
3. Post your /etc/rc.conf
4. How you configured network at your host system (ESXi) (NAT, bridge, etc)

UPDATE: You tried to get that file by network ? Or you copying it around VM's ? And btw, Windows server 2012 is the other VM (did you turned off it's own file sharing ) ?
 
1. Yes, VMWare tools is installed.

2. /etc/rc.conf below:
Code:

I saw this message pop across the console when the transfer finally failed:
Code:

Not sure if this helps point us in a better direction.
 
Hi again,

As you have said before you have a first VM Windows 2012 Server. With AD functionality it will do few shares and will have file-sharing turned on by default - you are trying to mix it with a second virtual machine with a FreeBSD and Samba ON - just tell me - what you want from this ? You really think it will work ? they are both using one port and one address to distribute files on one ethernet adapter - how it will work ? you have bridged it!

Windows 2012 Server (with it's smartscreen on) will stop you from downloading WinMD5.exe.

And more - here your logs - you have a problems

Hello,

So I checked SmartScreen under Action Center on the Windows Server and it is indeed disabled, where did you see it being enabled?

Regarding the bridged network adapters... I've known "bridged" to have several meanings. This article from VMWare might help give some insight into what they mean by "bridged" network.

As far as how I think it will work? I've seen several environments where people are running hundreds of VMs off a single ESXi box... I'm trying to run around 5 on something that can easily handle over 20. ESXi is designed for enterprise deployment, they just happen to have a free version available on their web site. If you've never messed around with ESXi, I strongly recommend giving it a shot, a great learning opportunity :)

As for the GEOM messages, I would think that the zpool scrub would have caught something, and if this was a ZFS issue then my previous test of moving data to a UFS partition would have allowed me to copy the data to my windows host. Further, if this was a ZFS issue, I think I would have been unsuccessful in copying data from my zpool to the UFS partition, let alone using SCP to pull data off my zpool over to windows. I think it's safe to say we can set the ZFS variable to rest for troubleshooting this one ;)

Code: 
root@Atlas:~ # zpool status
  pool: transition
 state: ONLINE
  scan: scrub repaired 0 in 0h6m with 0 errors on Mon Feb  8 08:05:27 2016

  da1p3  ONLINE  0  0  0

root@Atlas:~ #

Now all that said, if those messages mean something that the scrub didn't tell me, please let me know so I can get a new thread created to address the ZFS issue separately from the samba issue being discussed in this thread.
 
I actually missed the part last night when I responded where you mentioned the VMs having "one address" - yes they are sharing an ethernet adapter but in a virtual environment, that means nothing. Each VM has it's own IP address and even their own unique MAC address.
 
Hello all.

I have almost the same problem. Sometimes users when they will copy one or more files between folders or shares, I saw some samba processes eating 100% CPU, and the LOG show:

Code: 
[2016/06/04 20:36:36.210180,  3] ../source3/smbd/smb2_read.c:261(smb2_sendfile_send_data)
send_file_readX: sendfile sent zero bytes falling back to the normal read: folder/somefile.jpg

And in messages I saw:

Code: 
Jun  4 20:37:38 samba smbd[74371]: [2016/06/04 20:37:38.387444,  0] ../source3/smbd/smb2_read.c:290(smb2_sendfile_send_data)
Jun  4 20:37:38 samba smbd[74371]:   smb2_sendfile_send_data: fake_sendfile failed for file folder/somefile.jpg (Connection reset by peer) for client ipv4:192.168.0.40:64346. Terminating


In tests, when I activate "use sendfiles=yes" in smb.conf, this errors occurs. But if I set "use sendfile" to no (default), the same files can be copied.

Maybe a trouble with Samba "use sendfile" directive?

Using: FreeBSD 10.3 Stable x64
Samba 4.4 (standalone mode) installed from ports
UFS filesystems with ACLs

This is port options, almost all in default

I can corroborate what EnioRM reported — my Samba 4.3.9 performance rebounded when I set "use sendfiles=no" instead of "yes".

Code: 
10.3-RELEASE FreeBSD 10.3-RELEASE #0 r297264: Fri Mar 25 02:10:02 UTC 2016
 
Hey guys, I'm about to deploy a FreeBSD instance for testing with Samba and found this thread while looking for potential problems. Since this is a replicable issue, did anyone file a bug report with the Samba team yet? Any updates are appreciated.
 
I've had problems with "use sendfile" too. In my case, trying to start VMware Workstation virtual machines from a Samba share would fail with a message "The operation on file ...vmdk" failed (Retry/Continue/Cancel). In the Windows eventlog I see from source Mup event ID 139: "{Delayed Write Failed} Windows was unable to save all the data for the file \\server\VMs\vmware.log; the data has been lost. This error may be caused by network connectivity issues. Please try to save this file elsewhere.".

After setting "use sendfile = no", the virtual machine started without problems from the Samba share and there were no "delayed write failed" messages in the Windows eventlog.
