zfs

I have a new (to me) Dell R730 with 15.1-RELEASE. I have a single stripe zpool. I am using the mrsas module. When I installed the system at the outset, I chose ZFS root and I elected to partition with GPT +BIOS +UEFI. When I did the installation, I used BIOS mode. I had planned to transition to...

I have a CSM (non-UEFI) bhyve VM installed into .img with a zroot inside - but how do I grow the disk size now? I tried truncate -s +20G disk.img - but that hangs the VM during boot. I tried recovering gpt backup+growing the partition to the end, but that prevents VM from even loading the menu.

hi fellow, have got unsuspected behavior in Zpool volumes and am looking for a workaround, if any, or at least better understand of my system. shortly the goal : fill an USB memstick with same-size, plain-text files; then delete the content of the files, leaving untouched the name and...

Hi *, my system is regularly (approx. once daily) panicing with one of the following stacktraces: panic: vm_fault_lookup: fault on nofault entry, addr: 0xfffffe01a7041000 cpuid = 3 time = 1788555071 KDB: stack backtrace: #0 0xffffffff80bb434d at kdb_backtrace+0x5d #1 0xffffffff80b65bb1 at...

hi all, i recently learned abour sylve and was eager to try it. stop me if i'm wrong but it looks like proxmox, which was also something i wanted to try on one server. so i did install sylve and unfortunately it works only on zfs pools. so my system is a laptop with a ssd hd with the system and...

I have had these errors in the log for a few days (new hard drives are already sent from our supplier): (ada3:ahcich3:0:0:0): WRITE_FPDMA_QUEUED. ACB: 61 00 98 a5 01 40 3a 00 00 06 00 00 (ada3:ahcich3:0:0:0): CAM status: Uncorrectable parity/CRC error (ada3:ahcich3:0:0:0): Retrying command, 3...

I have a server that is still on 15.0-RELEASE and I was going to update to 15.1-RELEASE following the instructions provided here, starting with creating a backup with bectl. Bectl did not work, which I came to learn had to do with the layout of my root zpool. For some reason after installation...

I still do not quite understand how, and in what order, ZFS boot environment (BE) interacts with the running kernel, with a new kernel, and with userland. I have some doubts about the order of the steps in FreeBSD 15.1-RELEASE Upgrading Instruction via freebsd-update. Is it meant only for UFS...

Hi everyone I have had a strange problem while upgrading to 15.1-RELEASE The system would still stick to boot 15.0p9, even after all the upgrade procedures went fine. # freebsd-update -r 15.1-RELEASE upgrade # freebsd-update install # reboot # freebsd-update install ... I have a zoo of...

Backup your home directory on Freebsd to an external drive using zfs send and recv after sending an initial zfs snapshot to the drive and you can then send the latest zfs snapshot together with the initial snapshot and it will send the changes between the two...

My power went out while building ports via poudreire (I don't know whether it is related or not, but I figured I'd share it). Upon reboot, several files and directories are in a 'phantom' state. As far as I can tell, the files that were impacted were not being edited at the time or are...

Hello everyone, I'm having trouble destroying the partitioning scheme of a drive I have just plugged into my home server setup, in order to increase the redundancy of a zpool containing a vdev of currently 2 mirrors. From reading what I can find on this forum, I looked into /etc/fstab to make...

Hi there, I am currently running TrueNAS Core 13.0-U6.8 on a server, the last version of TrueNAS with FreeBSD. Since this project is going in a direction I don't like, I decided to migrate my server to vanilla FreeBSD. :) The current setup is not very fancy, basically a file server exposing...

As part of a larger project of reinstalling a server and moving from UFS to ZFS on my VPS, I decided I would back things up - using dump. Is there any way I can inspect the blob it outputs? I'd like to verify what's in there and what would be restored at a later time before wiping the current...

It improves operational stability by default. Also runs nightly tests on FreeBSD-13.5 (in addition to 14.x and 15.0), and ties up some loose ends in the docs. If you missed 1.17, it also improves handling of snapshots that carry a `zfs hold`. Also improves monitoring of snapshots, especially...

First of all, this is not a question about ZFS-on-GELI vs. ZFS native encryption, which has been addressed many times exhaustively on this Forum. I understand the differences between the two conceptually and in terms of metadata visibility, performance, etc. I have also read...

I have one storage device ada0 which does include several partitions. The laptop is a Lenovo T480. This is not my main laptop but my "testing lab". I have one efi partition on ada0p1 which has got Limine installed. The linux systems using this partition as the boot partition. The ada0p2 is my...

With BTRFS I could do bash completion of my snapshot names during send/receive, the names were just folders. With ZFS, there is no autocompletion if you use a script and pass snapshots as parameters. And if you could pass snapshot names as folders .zfs/blahblah, you'd get autocomplete, but zfs...

My server became unavailable and became stuck in a boot loop when I rebooted. Looks like a kernel panic related to zfs. I'm thinking it may be due to a full disk. Not sure how to resolve. The only error that jumps out is... panic: Solaris(panic): zfs: adding existent segment to range tree
