zfs

Scenario: There are five vdevs that are SATA Hard Disks. The array is fully operational and online. The file systems are mounted, but there is little activity besides the typical programs expected on a FreeBSD machine. I remove one disk. Is there ever a point where the disk becomes so out of...

EDIT: For anyone looking for the solution, it was to install the net/realtek-re-kmod package. Though in my case, since my system was not up-to-date, the critical first step was to update to the latest RELEASE version of FreeBSD. I'm replacing a NUC that I use as a server with several services...

Hello, I struggle to find an option which sets custom units to list/show datasets and zvol properties. Anybody knows?

Hello, I have Void Linux with a ZFS Root installed, it would be possible to create a FreeBSD subvolume on the zfs pool and boot it from GRUB without much problem? And if possible, use the same /home?

Hi, It's weird, my FreeBSD 13.2 lost my home folder. I did'nt do anything to the system and it just lost. I'm using ZFS and have FreeBSD pot on it anyway.

Looking for help with ZFS. I am booted into a live FreeBSD 13.2 trying to fix my zroot. Zpool import returns ZFS filesystem version: 5 ZFS storage pool version: feature support (5000) pool: zroot id: 8141163279847660127 state: online Status: some supported features are not enabled on the pool...

I have a bhyve vm running Rocky Linux 8.7 (RL). I have vm-bhyve installed. I need to test that the upgrade to RL 8.8 will not disrupt the user application running on that vm. My plan is to clone the production vm and perform the upgrade on that. If everything goes well then I would like to...

I have a zfs pool which was originally setup as encrypted. Due to some hardware errors I replaced an encrypted member with its unencrypted counterpart. In other words: zpool replace zroot /dev/ada0p4.eli /dev/ada0p4. A second drive was also replaced and so I now have this: [root@vhost03 ~...

Hi all, I have been grappling with a problem with my ZFS array for the last year or so, and it has reached a point now where I have run out of ideas of what may be wrong, so posting in the hope someone has some advice. I have a machine with 14 drives, configured like so: 4x 10TB HDD in ZFS...

I am preparing to replace a failing disk in a RAIDZ2 array. I received a heads up from our weekly HDD status report: vhost03.hamilton.harte-lyne.ca - ZFS pool - HEALTH fault NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT bootpool 1.98G 234M 1.76G...

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...
