zpool

I have a FreeBSD production system with 12 3TB SATA drives in a a JBoD triple-parity ZFS configuration spanning around 30TB. This was working well for months, through numerous reboots, however after a power outage Friday it's been unable to boot, giving 3 or more (it varies) `zio_read error...

My old zpool raidz1 was maxing out and one of the hard drives was starting to go bad. I created the new zpool using new and bigger drives and now I need to transfer the files from old zpool to new zpool. Can I simply copy and paste or mv/cp the files over or do I need to use export/import? Both...

Hello and thanks in advance! I have local home FreeNAS server with ZFS pools on and a couple of 4Tb hard drives connected. Didn't use mirroring, shame on me. One of the drives partially died. I mean, gpart gives me partitions, but I get IO error when try to mount it. So now I have an image of...

Hi, I need to move zpool to faster SSD disks. I'm new to ZFS so I may be wrong but I assume that the best way to do this is to create zpool on new disks again and then send 'zroot' over 'zfs send' command. Am I right? My zpool status output: NAME STATE READ WRITE CKSUM...

Last time I tried this, I had trouble where the box would not boot. I think the device id of the usb external disks changes on reboot. I wonder if this is solved by plugging all the external drives in and rebooting before I add anything. Should there be a way that ZFS just knows which drive is...

Hello all, Finding myself at a crossroad. Need to transfer my home files to a new zpool with bigger drives but not sure if I should get smaller but more cost-effective HDD and wait for SSD prices to drop in the next 5 years or so, OR should I get bigger and costlier HDD for future-proofing...

Hi I have just installed Freebsd on my old Macmini and want to transfer zfs datasets from a usb drive to the macmini I just need to copy across some data and set up a few config files to get macmini set up, so i can finally ditch osx and go full freebsd on all my machines Is it possible to do...

Using a live media, I have taken a dd image of my main encrypted zfs GELI FreeBSD partition (not the entire disk) and of the encrypted key file as well. The dd image and the encrypted file are on an external disk now. Now I started FreeBSD normally, I did mdconfig and did a geli attach of the dd...

I have real zpool with files, but want to test firstly. I created simple zpool with files: # zpool status -v pool: ztst state: ONLINE scan: resilvered 19.5K in 0h0m with 0 errors on Thu Mar 14 14:44:20 2019 config: NAME STATE READ WRITE CKSUM ztst...

Hi, everyone! There is two hard drive on the system % uname -a FreeBSD desktop.freebsd.lan 12.0-RELEASE-p2 FreeBSD 12.0-RELEASE-p2 r343203 OptiPlex amd64 Description of the connected disks: KINGSTON - SSD disk with newly installed FreeBSD 12.0-RELEASE-p2 WD - old SATA disk with FreeBSD 11.2...

I did freebsd-update from 11.1 to 11.2-RELEASE, but I did not have enough disk space and "freebsd-update install" stage failed (No disk space error) - so my system is screwed. I booted from FreeBSD 11.1 install ISO (LiveCD) and I thought I would rollback the ZFS snapshots on the zroot pool and...

I have a pool on a system that can only be imported as read-only (it has a feature flag enabled that FreeBSD doesn't support). However, I'd ultimately like to destroy it and recreate it under FreeBSD, but whenever you zpool destroy a read-only pool it acts like you've exported it, not destroyed...

Dear community, I'd like to kindly ask you for a little help in my situation: I'm running a ZFS pool of 3 drives. What happened is - a power cable powering 2 drives had a bad contact, so I started loosing 2 out of 3 drives and having a lot of UDMA errors and CAM status timeouts etc. Yesterday...

I'm trying to create encrypted raidz, but how? https://www.digitalocean.com/community/tutorials/how-to-configure-an-encrypted-zfs-pool-with-digitalocean-block-storage-on-freebsd If I understand correctly, I need to encrypt every disk before creating zpool, like this: % sudo gpart add -t...

Dear friends, I am migrating from Debian GNU/Linux to FreeBSD. I could be using KfreeBSD, but I prefer blending-edge and also become part of a community, so I will not stick to Debian, although I appreciate the spirit. The server board has 32 CPUs, 32GB of RAM, 1 x SSD and 5 x SATA disc...

Hello, Today I upgraded my FreeBSD 11-STABLE to recent version r322164. After that I cannot boot from my pool: Booting from Hard Disk... ZFS: unsuported feature: org.illumos.sha512 ZFS: pool zironroot is not supported gptzfsboot: failed to mount default pool zironroot FreeBSD/x86 boot Default...

When I run command pkg update on FreeBSD 11.0 I'm getting this error: [srv]# pkg update Updating FreeBSD repository catalogue... pkg: Repository FreeBSD load error: access repo file(/var/db/pkg/repo-FreeBSD.sqlite) failed: No such file or directory Fetching meta.txz: 100% 944 B 0.9kB/s...

I have a single disk on my server. I simply went for ZFS "stripe" (no redundancy) when installing FreeBSD. zpool status prints the following: pool: zroot state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 ada0p4 ONLINE...
