zfs

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...

Hello I have a jail configured like this: jellyfin { # STARTUP/LOGGING exec.start = "/bin/sh /etc/rc"; exec.stop = "/bin/sh /etc/rc.shutdown"; exec.consolelog = "/var/log/jail_console_${name}.log"; # PERMISSIONS allow.raw_sockets; exec.clean; mount.devfs; allow.mount = true...

Has anyone thought about implementing pubgrub versioning solver for FreeBSD (BSD) base system(s)? I was going to save this for my stealth project but I gift it to the BSD community. PubGrub versioning solver is a key algorithm that makes uv (written in Rust) so fast. It is used for package...

Hello, I'm confused about what it means for a dataset to be mounted and how zfs send & receive backup my system. In my case, I backup my root filesystem on a pool located on another physical disk zfs send -R zroot@snapshot | zfs receive -Fu external-disk-pool/backups/zroot I use the the -u...

Hi, Something strange is happening with a directory on one of my ZFS partitions: $ find deleteme/ deleteme/ find: deleteme/: Input/output error $ cd deleteme/ $ ls $ cd .. $ rm -rf deleteme rm: deleteme: Input/output error $ find . -name 'deleteme' -type d ./deleteme find: ./deleteme...

I'm going to upgrade an old server from ZFS 0.8 to version 2.3.0 and want to clarify a few key points before proceeding. If anyone has experience upgrading from 0.8 to 2.3.0, I’d greatly appreciate your insights. 1. Are there any particular steps in the upgrade process, both before and after...

Is it possible to boot FreeBSD 14.2 (UEFI + ZFS + GPT) using GRUB2-EFI? # grub-install --target=x86_64-efi --efi-directory=/boot/efi/efi/ --bootloader-id=grub --boot-directory=/boot/ --modules="part_gpt part_msdos bsd zfs" grub-install: error: relocation 0x4 is not implemented yet. root@ykla:~...

After a power failure, my system booted with the following message: \ Some googling on the unsupported feature: com.delphix:head_errlog message led me to this helpful post: https://unixdigest.com/tutorials/upgrading-to-freebsd-14-how-to-fix-a-broken-bios-bootcode.html I followed the...

Good afternoon, I'm doing some testing of ZFS and ran into this the first time I tried to send a pool to another pool. (Technically snapshots, but starting with the filesystem named for the pool.) warning: cannot send 'send/test/l0_1/l1_0@syncoid_vulcan_2025-02-01:07:30:13-GMT00:00': signal...

Hello, I've cloned the installation of FreeBSD to an external SD card and now I have another hard drive available for my RAIDZ configuration. This is the pool: ~ [prometheus] % zpool status stranger pool: stranger state: ONLINE scan: scrub repaired 0B in 00:14:48 with 0 errors on Thu Jan...

Hello. I created new vm, here is config: vm config loader="bhyveload" cpu="6" memory="8G" network0_type="virtio-net" network0_switch="public" disk0_type="virtio-blk" disk0_name="disk0.img" disk1_type="virtio-blk" disk1_name="disk1.img" disk2_type="virtio-blk" disk2_name="disk2.img"...

hello, so I set up NAS: RAIDz2 of 8 x WD hc530 with special vdev (Samsung PM963), Ryzen 8400f, 32 GB ashift=12, recordsize=4M, others are quite default playing with compression types I clearly see reasonable cpu load with compressions during write. But I don't see it for reading (while speed...

Hi, I've got the following problem. I'm writing a script to set my ACL on my ZFS Samba file server. Some facts: NFSv4 ACL entries are evaluated in their visible order. In Windows ACLs, the deny permissions generally take precedence over allow permissions. This means deny ACL entries must be...

I'd like to be able to recover from a scenario where / filesystem is corrupted. Like if I inadvertently delete some or all configuration files in /etc or the procedures in /boot for instance and may not be able to boot anymore. What I've done so far in a VM to learn how to do that kind of...

Hi, I am using FreeBSD 14.1 with ZFS in mirror configuration on GELI encrypted partitions. My root-pool looks like this: How would I go about changing references to using GPT-labels instead? Thanks in advance!

Hi! I've moved FreeBSD from an old disk to a new one. The disk has 50 GiB space available. Partitions are (it is a gpt partitioned disk): # gpart show => 40 104857520 vtbd0 GPT (50G) 40 1024 1 freebsd-boot (512K) 1064 12582912 2 freebsd-swap...
