zfs

Hi, in older version of FreeBSD zfs pools were visible after reboot and in their history was not filled with repeated "import" items. After a break i get back to FreeBSD 14.0R/14.1R and i see that on every reboot non boot pools have new "import" item. Is there a way to have additional non-boot...

Which method (or utility set) would be best for making EVERYDAY ZFS snapshots of server’s current FreeBSD system (whole system installed but NOT THE WHOLE DRIVE) to internal USB 2.0 pen-drive? Need to NOTE: this USB 2.0 pen-drive are FORMATTED as bootable (by periodically downloading from...

Hello. I've been using FreeBSD on my pc for about a year now and decided to go fully FreeBSD, removing other multibooted OSes from my desktop. Currently I have a single 300GB UFS partition on my HDD that I used as root on FreeBSD. I'm trying to install one 120GB SSD for the OS and two 2TB HDDs...

Hello everyone, I am running a homemade NAS server (consumer hardware with a lot of storage), and I am migrating my data that was all on an external USB disks. I tried out many methods and tests before running a production environment (including installing a base 14.1-RELEASE). Currently I am...

Hi, Currently I have a zpool that does not work anymore. The name of the pool is zroot. The VM was running in FreeBSD version 14.1 and got in a faulty state when the host hang. ZFS is always better then no ZFS (Dan Langeville), I would like to learn from this broken state. The gpart show...

I cannot use the script from ZFS dtrace scripts to print the correct value of zfs_dirty_data_max, and the output is as follows: CPU ID FUNCTION:NAME 2 85224 none:txg-syncing 41MB of 0MB used 0 85224 none:txg-syncing 25MB of...

Have not touched linux (redhat) since right before xwindows was new. My plan is to set up a machine from used parts to work like a file server with a bunch of Raid5 of 4TB spinny HDD's and its main job will just be to nightly make backup copies of my PLEX media repository. But I would like to...

I encountered a boot failure after switching the boot drive from a sata ada0 to a nvme drive nda0 with attaching/detaching, by executing the following commands: zpool attach root ada0p5 nda0p4 # after resilvering done zpool detach root ada0p5 Also, I installed a new ESP on nda0 mount_msdos...

My question is about atime. I have read numerous sources that indicate atime=off is a performance enhancement. Since the device I am creating is primarily a squid proxy server they also recommend "atime=off" for their associated caches and data. Starting here Root On ZFS and continuing with...

I have an application where we run many services in jails. Each service is isolated from the others and keeps its local data in a ZFS dataset that is passed into the jail. We're working on increasing redundancy in the system. Right now we are using ZFS snapshots sent to a backup server to cover...

Hello, How to deal with the situation when the external drive with ZFS was temporary disconnected / power loss. After reconnecting drive: # zpool status pool: zrbackup01 state: SUSPENDED status: One or more devices are faulted in response to IO failures. action: Make sure the affected...

Hello, I am running a small proxmox server with two friends. We each have an individual vm (mine running freebsd, two others linuxes) no complain on that side. I am also running a small shared services freebsd vm that hosts an nginx reverse proxy, a postfix relay and a mediawiki instance. I...

Dear FreeBSD Gurus! Please suggest shell script (probably must be complicated) to remote Installation of the FreeBSD Operating System Without access to a Remote Console. Most of You already read Remote Installation of the FreeBSDOperating System Without a RemoteConsole article, based on Martin...

First a bit of background: This is on a FreeBSD14 relatively older machine (CPU: Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz (2593.86-MHz K8-class CPU), with a 4 port Gbit ethernet interface (bge1: <HP Ethernet 1Gb 4-port 331FLR Adapter) and 384GB of RAM. a few ZFS pools set on 4x 8TB SAS drives...

Since there is no tutorial how to migrate a UFS installation to ZFS, I'll give my 5-cent contribution. Done this procedure yesterday at my home server that I run several services like Nginx + PHP, Samba, Transmission, Plex, Bhyve VM's, etc. You'll need a new disk that can hold all your data...

first part of my zpool administration infographics is ready, i hope it helps. modified as per suggestions..

All, Looking to implement a dedicated server to perform data processing/analysis and it needs some fairly significant I/O. The "twist" is that the data's lifespan is the duration of time it takes to import, process, analyze and report on - then the database and the data is deleted. Storage...

I discovered on BTRFS a metadata bloat problem. Basically, I copy an nspawn container folder (several gigs), and the metadata usage gets bloated by 115MB. As it's CoW a typical user would expect almost no extra space taken by this action (even being remotely aware of some overhead) and will not...

Hey folks, I'm migrating a server to OpenZFS. I mounted the /poudriere dataset to another disk/zpool. My question would be whether it is worth creating a /ccache dataset, or whether to create /ccache on a UFS disk. I just have 8GB RAM. Would a /ccache dataset be too overwhelming? Or a simples...

Hi all, I am trying to create an encrypted zfs volume that will be auto-mounted using a keyfile. According to online information this should be possible with the following command: zfs create -o mountpoint=/home/ -o encryption=on -o keysource=raw,file:///usr/local/homekey disk/home However...
