zfs

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...

Hello! I want to switch from legacy boot to UEFI on installed FreeBSD machine without losing data. I have such layout: gpart show 4725[0] =>...

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...

I'm finally reading the Second Edition of "The Design and Implementation of the FreeBSD Operating System" and found this passsage: > The ZFS filesystem integrated from OpenSolaris is the one exception to the integrated buffer cache. ZFS has its own set of memory that it manages by itself. Files...

Hi all, is there a way to send a ZFS dataset with its inherited properties (possibly making them local properties in the process)? If not, is there a way to convert inherited properties to local, which I would do before sending? I mean with the ZFS tools by the way; not scripting (which I will...

I can't seem to figure this out. I got to the point where a mount would "work", ls shows nothing, but I can cd through the folder structure of the mounted NFS share. I have no idea what I am doing wrong, and neither does the Internet, apparently... NFS Server / Wireguard Client config...

this isn't a problem by itself, but i want to know what the mechanism for it is, as i can't tell just by reading the rc script itself. the reason i want to know is that i have a custom rc script which i use to mount a usb thumb drive, containing my zfs keys, on boot, before the zfskeys rc...

I've been using this ZFS pool since FreeBSD 7.4 (AFAIR) as my home storage, but a few months ago the host started panic'ing every 2-3 days. What's strange is that it can (and routinely does) complete a zfs scrub with zero problems. panic: Solaris(panic): z: blkptr at 0xfffffe014c1602e0x DVA 0...

At least for my personal taste, without trying to figure out "why would I do that?" I'm looking for a way to tweak Installing FreeBSD Root on ZFS using GPT by giving the ZFS root a whole disk instead of just a partition. ¹ I had no problems setting the swap partition on another disk. But when...

Dear community! I want to give FreeBSD a try. My first mile stone is a fully encrypted headless system, i.e. which can do boots without interference. The idea is to have an USB stick holding an unencrypted ufs with /boot-dir and the key file, which decrypts the main drive's partition holding a...

Hi, Recently I've noticed that my file server makes about half a second of spinning disk access noise about every 2 seconds. Crunch...1....2....crunch....1....2.... etc. I inspected top and iotop, turned on/off services etc. trying to figure out what is causing this. Eventually figured out...
