zfs

I'm trying to troubleshoot a potential slowdown when doing zfs send receive between two machines. Both servers are running 13.2 and are pretty fast hardware wise. When I transfer a file from A -> B via FTP, I'm getting 700MB/sec When I transfer a file from A -> B via SCP, using Cipher...

Hi, My cache/log SSD recently died I was able to remove both cache and log device, and replace log storage,: [root@numenor ~]# zpool status -v pool: zroot state: ONLINE scan: scrub repaired 0B in 07:00:39 with 0 errors on Wed Apr 5 15:45:21 2023 config: NAME STATE READ...

I initially had FreeBSD 13 on a 512 GB NVMe SSD (ZFS root and GELI encryption configured via the installer). Later, I bought two 8 TB hard disk drives. I reinstalled FreeBSD 13 but this time on the two 8 TB HDDs instead of the NVMe SSD. In the installer, I chose ZFS root on the two HDDs (2-disk...

I have two hard disks of the same size, and one 512 GB NVMe SSD. I am planning to install FreeBSD root on the two hard disks (ZFS mirror). This will create a ZFS pool with one vdev that consists of a two HDDs that mirror each other. I am thinking of using the 512 GB NVMe SSD to store /usr/ports...

Hi all, when adding a second disk to my zroot boot pool, I basically followed this guide: https://dan.langille.org/2019/10/15/creating-a-mirror-from-your-zroot/ My source device is ada1 and the new one is ada0, so I had to swap the device names in the commands and it seemed to work fine. The...

Hi FreeBSD Gurus! In case using bsd-based bare metal rack server as a gate fw/router: 1. How effectively would be using ZFS (in comparison to GPT, etc) file system in hardware RAID10 (4 of SSD TLC/MLC drives) ? 2. Is separating of /var, /tmp (also may be /usr) to another disk's logical volume...

I have a server with a mix of pools ssd & SATA disks, I started to notice that the server began to reboot frequently, I manage to boot in single mode, and notice that no more reboots, then I boot the pool with the oldest SATA disks and after a while, it restarted (no logs in console) also no...

I created raidz with labels and geoms /dev/ada1pX /dev/ada2pX /dev/ada3pX /dev/ada3pX as well as /dev/gpt/$labels existed before reboot. It was like this: pool: hddPool_x3_RAIDZ state: ONLINE config: NAME STATE READ WRITE CKSUM...

It wasn't clear to me on the installer how I would Raid-1 3 sets of drives and then Raid-0 those 3 sets. Basically 2 x Raid-1 2x Raid-1 2x Raid-1 And Raid-0 the 3 logical drives. I hope I have explained well what I am looking at doing. If this is not something that can be done from the...

Guys I changed my disks in my T430 to make a better backup routine. Before I had a strip with 3 ssd's with 1 tb each. I changed to root in a 240gb, home in a 1tb, and I left 1tb for dual booting with OBSD. And the last 1tb I took out of the note and put it in a case for external use. Everything...

Last week I experienced a major problem after upgrading packages to the latest quarterly which I couldn't even resolve by reverting to an earlier boot environment so I decided to restore the entire system from my backups. The zfs pool for my system is normally a mirror with two drives. As a...

I have a desktop that has a 512 GB NVMe SSD. I am planning to repurpose the desktop as a file server by adding two 10 TB hard disks, and installing FreeBSD with ZFS on those two 10 TB hard disks (RAID 1, i.e. two disk mirror). It seems that I no longer have any use for the 512 GB SSD in this...

I set up a Samba server with samba413 last week, but recently it has been having a strange error. It is unable to connect to a directory in a zpool that has permissions 777. The smbd is also currently running as root. I tried reinstalling and switching from samba413 to samba416 to no avail...

Hi. OS 13.1, Raidz1 on 4 disks for video surveillance data. ~8tb of mp4 files. No snapshots. Recently i'v rewrited all of this data with something like this: ffmpeg -i old.file.mp4 new.file.mp4 mv new.file.mp4 old.file.mp4 After that ~2T of space on this pool disappeared. How i can fix this...

Hi, When on certain pools or datasets large files will be stored, it can be an advantage to use a larger recordsize of 1M in ZFS. Suppose the pool is encrypted by GELI, would it be better or worse to align the sectorsize of GELI with the recordsize of ZFS? In general i see GELI sectorsizes of...

Hi everyone, I created a new ZFS dataset root@vieron:~ # zfs create zroot/playground root@vieron:~ # ls -ld /zroot/playground/ drwxr-xr-x 2 root wheel 2 Mar 17 12:40 /zroot/playground/ and assigned read and write permissions to the "labgroup" group root@vieron:~ # chmod 775...

Hello everyone, I wanted to share an article that I recently wrote about migrating from Proxmox to FreeBSD's bhyve hypervisor. The article covers the process of migrating virtual machines, storage, and networking from Proxmox to bhyve, and includes tips and tricks that I learned along the way...

Hi, I have set up zfs send | zfs recv replication as an unprivileged user. The purpose is to have an off-site backup process that is a) fast, and b) secure, in the sense that a successful cryptolocker attack on the primary backup would be partitioned off by the dint of append-only replication...
