zfs

Hello I'm working on the broken zpool. All attemps to import, including zpool import -F -T 12855264 -R /mnt -f rpool, resulted in Dec 4 12:56:54 freebsd kernel: Solaris: WARNING: can't open objset 1035, error 5 Dec 4 12:56:54 freebsd ZFS[10143]: pool I/O failure, zpool=rpool error=97 Dec...

To reorganise my zfs server, I need to vacate the tank, temporarily. It's currently configured with 5 x 3 TB disks in RAID-Z1 format. These disks are nearly 10 years old. Two of the originals have failed already, and I want to move to RAID-Z2 as soon as possible. I already have two spare...

Hi, I know it's a known bug, but I just want to clarify a few things, because it's not clear for me. So, when the ZVOL name is too long, and volmode is set to GEOM, we see that no device is created under /dev/zvol... path, and we can see error=63 in /var/log/messages. My understanding was that...

Hello, I have problem witch stat command, when create file the time stamp st_birthtim show date Jan 1 00:59:59 1970 The full command: root@pwgcz:~ # stat test.txt 100 79525 -rw-r--r-- 1 root pg 0 0 "Nov 19 15:53:20 2021" "Nov 19 15:53:20 2021" "Nov 19 15:53:20 2021" "Jan 1 00:59:59 1970"...

Hi there, I'm curious if it is possible to create sub jail in jailed enviroment (Jail + ZFS) HOST -> JAIL -> (subjail1, subjail2...) If the answer is Yes, what should I do, what to read?

On a FreeBSD13-p5 system with two zfs pools, each 6x18TB (ada0-ada11) with 4k sectors (sector size logical 4096, physical 4096, offset 0), gptzfsboot takes about 3 minutes to reach the bootstrap loader. There are no error messages. BIOS drive C: is disk0 BIOS drive D: is disk1 BIOS drive E: is...

I need to provide a network drive for an SME with 100 TB usable capacity. I would like to use a ZFS raid-z3 pool consisting of 14x 12TB SAS or SATA drives (this will be a rare-write/many-reads situation). I have been looking at chassis like the SuperMicro SC846BE1C-R1K03JBOD. Given that I'll...

I had this same problem some months ago over nixos with root zfs and the 'best answer i got' was it can't be done with openzfs and i should planned this and i agree but the point is not that i shouded plan this instead is i didn't, now how can i do that?. i founded this guide over vultr about...

I'm stumped here - trying to delegate a zfs dataset to a jail (using another pool) within iocage... My config has what appear to be all the proper settings to allow a root user in the jail to manage zfs, and it all seems to work, but I cannot unmount any datasets. Here's the config: {...

Hi Guys, I need to create a Encrypted Volume, backup it and transfer to another FreeBSD machine without SSH access. I was successful in doing this, but I don't know if I do it the best way. If there is a better way,, please let me know. 1 - First I create de zroot Volume $ zfs create -V 1g...

I've just had a "wonderful" time thanks to whoever maintains zfs - after doing a zpool upgrade, it told me to do It didn't even tell me that this will break my EFI boot. Granted, I was stupid to simply believe what I read and to do it anyway, since it says "mbr" in there. Here comes the...

Generally "zfs send | zfs receive" works very well. But when we transfer several datasets from one pool to the other only the first mountpoint is set as expected: Using: zfs send -R zDataStorage8Backup/datasetShares@auto-20211027-050000 | zfs receive -Fd zDataStorage8 creates correct...

Hi, I have 12 disks in a raidz2 system (2 vdevs) that I use mostly as NAS for storage (backups and few movies). Given that the system is basically write once, read many, I'd like to be able to use most of the available space. ZFS by default is reserving 1/32 of space for operations, and I...

Hello, I've been using Debian Linux for some time, but I wanna give FreeBSD a try because I like some facts about it. :) I do the first steps in a VM for easy rollback, but after that I'll install it on the 2nd drive on my laptop. Because its a laptop, full disc encryption is mandatory for me...

This is probably a trivial question, but I'm failing to figure it out myself after reading a lot of documentation. I've my laptop running an up-to-date 13.0-RELEASE, with zfs on top of geli. So, datasets are *not* encrypted, but encryption is done on the lower level. I've a single snapshot in...

I was trying to create an encrypted zfs filesystem today and I got an error, so i tried to check the version and that gives me an error as well. Am I missing something? % sudo zfs create -o compression=lz4 -o encryption=on -o mountpoint=/mnt/zusb-backup -o keyformat=raw -o...

Hello, I have a zpool named zroot on top of 3-way mirroring (ada0p4, ada1p4, ada2p4), and zroot/data with mountpoint /data. Now I would like to set zroot/data to use a partition of a fourth disk (namely ada3p1). How could I do that? Thx for your helps.

Hi guys. I am a newbie in the BSD world. I've been using Linux for a few year just as desktop stuff, no development-related work. A few days ago I decided to give FreeBSD with ZFS a try. Anyway, I installed FreeBSD dual booting Windows in a disk, the laptop is legacy BIOS boot with MBR partition...

Hello, could you please recommend me a reliable and fast disk for a server which should host 3-4 virtual machines, which use a large data blocks ( eg 2TB volume for VM: zfs create -sV2T -o volblocksize=4k -o volmode=dev zvmpool/zcloud-disk0 ) At the moment I found those quite promising...

So as some on here know I have been using FreeBSD for a long time now, and was an early adopter with ZFS. For me the ZFS experience has generally been very positive on FreeBSD. However I started also using it in Linux with Proxmox a couple of years ago, whilst I haven't had any crisis with it...
