zfs

Anyone done this?

Hi, Noticed that my FreeBSD NAS was not accessible today. No ssh, no ping. Ripped it out from its home and took it to a monitor and I see this: It does this if I boot single user too :( I'm praying that the NAS mirror (also ZFS) is not dead. I assume this is the boot zfs that is broken...

Hello, I’m running a FreeBSD server with an iSCSI-attached storage (Dell MD32xxi). The iSCSI LUN contains a ZFS data pool (not root). Scenario: FreeBSD installed on local disk (root pool imports fine) Data pool ztank lives on an iSCSI LUN (/dev/da0) iSCSI login works correctly After boot, the...

So I start a simple rsync from a USB drive to my zroot user home folder. It works great. But then, while rsync is copying, if I try to import a ZFS pool from another device, it just gets stuck at "importing ZFS pool" and never completes it (although it seems to import it in the background after...

Hello everyone, I was going through some old ZFS snapshots after I stumbled on a particular snapshot that I could not delete: # zfs destroy -v zroot/jails/mantis@monthly-2025-07-01_05.30.01--6m will destroy zroot/jails/mantis@monthly-2025-07-01_05.30.01--6m Read from remote host...

This week I'll have finally the time to fix my computer broken from months... And I decided that I want to change completely the topology of the disks. My workstation, which is a decent (slightly old) laptop can host up to three disks: 1 m2 and 2 2.5" sata; my potential options are: Create a...

Hi all, I broke a gmirror that used to consist of two 12TB disks (ada2 + ada4). The UFS2 filesystem lived on /dev/mirror/mirror0. After tearing down the mirror, the system recreated it once on reboot, I removed the metadata again, and now: ada2p1 still shows a valid UFS2 superblock (file -s...

Hello! I am at my wits' end. I was trying to boot from a mirror and had some problems. I used zpool detach for the drive that the system could boot with. I Tried a some things but due to my stupidity at some point I used dd to clone the drive that could boot to the one I was trying to boot...

when e.g. scrubbing a readonly zpool, that scrub process hangs unkillable and even prevents shutdown and others, e.g. btop. I expect an error message, not a freeze. Reproduce: $ truncate -s 100M /tmp/100m $ doas zpool create -o compatibility=openzfs-2.0-linux demo-freeze /tmp/100m $ doas zfs...

I am relatively novice, with no Unix experience. I manage my barebone server for our small community, mainly for Web publishing (Textpattern), email (OpenSMTPD with Cyrus IMAP), and storage (Nextcloud) on FreeBSD 14.3-R. I do not have a spare computer for testing. After ZFS rollback disaster I...

how do I create a zpool e.g. with zfs 2.2.7 that I can import with zfs e.g. 2.1?

I'd like to format SD-cards and USB-thumb drives with zfs. When plugged-in I'd like them to automatically mount read-only, so that I can carelessly pull them out again. I guess I need a devd rule with zfs import/export and rmdir. Is there somebody here doing similar? How do you?

I've got several Z3 RAIDs; and recently had to do a routine swap on one of the clusters. That all went without error - but a few seconds into resilvering I got an unexpected 'insufficient replica' error; desite this being a Z3 raid with all other disk in good order. The process followed was...

I originally installed FreeBSD onto a single ZFS disk and now I want to create a 2-way ZFS mirror from this disk and another new disk and I want to make sure I do it properly. Here is the current ZFS zroot boot pool: # zpool status zroot pool: zroot state: ONLINE scan: scrub repaired 0B...

I have a FreeBSD 14-3-RELEASE VM that I've added a new mirrored pool, created ZFS filesystem and set the mount point. The problem I'm running into is that the pool does not get imported when the VM reboots and the pools filesystem is not mounted. I did a google search and it was suggested to...

Issue Description Booting a ZFS root using gptzfsboot or loader.efi from either 14.3-STABLE or 15.0-PRERELEASE fails with: ZFS: unsupported feature: org.openzfs:raidz_expansion Background I wanted to expand the raidz1 zpool where the root volume is, on 14.3-STABLE: - installed the openzfs...

Hello, I have an issue where the content of my disk seems to reset at a certain state after some time (hours). For instance, if I create a file in my home, the next day, the file will have disappeared. I first realized this with a jail I configured but whose configuration disappear after a...

Greetings, I'm using FreeBSD 13.5. I need to snapshot my /home/beastie directory but I made a bad mistake. I created datasets for directories. After that, I decided to create a snapshot for testing but I saw snapshot having "USED 0B". I mounted it and no file is seen. After all, I wanted to...
