after initiating the 11.2 upgrade on Sunday evening and finishing the kernel part of it,
the following reboot left me with a ZFS error:
ZFS: i/o error - all block copies unavailable
ZFS: can't find pool by guid
The pool layout is simple, just a single disk, so no RAID.
I find it...
I apologize if this question has already been asked before.
Is it possible to save a ZFS snapshot as a single file or directory somewhere for backup, and I ever need to "reinstall" FreeBSD, instantly restore my entire system using the install USB and ZFS?
I've made a lot of customizations and...
Hey Guys! :)
Whats the best / proper way to backup a zroot pool to antoher pool / drive?
2x 250GBs SSDs (zroot | mirrored)
1x 500GB HDD (backup drive)
My goal: Backup the entire zroot pool to the backup drive in a limited dataset (250GB) and regularly do automatic snapshots...
I'm currently trying to fix/recover a broken zroot pool.
Drives: 2x Samsung 850EVO 250GB SSD's (da0 and da1)
How I got into the problem: I accidentally removed the wrong drive from the server and I wiped the drive on another PC. When I...
I have a 120GB drive using ZFS that I'm cloning to a 300GB drive since I know I will outgrow it soon.
It just dawned on me that I've never extended a drive using ZFS before.
Partition 1) EFI (512MB)
Partition 2) ZFS data + OS root (111GB)
Partition 3) Not sure (15GB) maybe left over...
When I start deleting large amount of data (5-10 GB) the ZFS prioritizes deletion and system is VERY unresponsive.
Which ZFS parameter to change to make deletion of files a lot less priority for ZFS? ... or how to prioritize reads with ZFS?
Long-established box previously running 11.1-RELEASE-p11 on a ZFS mirrored pool. I've gone through the standard steps for upgrading a few times, including ZFS rollback/clone to pre-upgrade state with ZFS/beadm and always end up with the same result -- the 11.2 kernel freezes on boot, the 11.1...
As the title suggests, can I delete everything except the files I need in an external zpool?
My zpool before was a root-on-zfs but it experienced problems when booting, and I failed on reviving it. The only choice left for me was to zpool import cluster as a storage pool.
What can I delete in...
Good day everyone, I shutdown my FreeBSD server for a few hours and booted it and it would not boot.
I was greeted by this error
FreeBSD/x86 ZFS enabled bootstrap loader, Revision 1.1

I am trying to configure FreeBSD 11.1 auto installation using the mfsbsd utility, Auto installation works fine when I define 6 partitions but when I try to configure more than 6 partitions then it failed with no space available index '9'
While checking the mfsbsd scripts do_gpt.sh under...
I just wanted to share a small but handy script with the community, as I think more people than me could find it useful!
You have some dangerous command which could alter your system in a bad way, e.g.:
$ pkg upgrade
$ portmaster -a
$ some_cmd --force --overwrite...
As we're running out of disk space, I've added another block storage device and made it a zfs partition with gpart :
$ gpart show
=> 40 125829040 vtbd0 GPT (60G)
40 1024 1 freebsd-boot (512K)
1064 6291456 2 freebsd-zfs (3.0G)
The other day I got a new backup HDD so I can rotate my external disks and take them offsite in case my house blows up. I enjoy disk encryption on these sorts of drives that will be stored safely and the data is inaccessible. However, after backing up my data I realized that I didn't employ ZFS...
I am running successfully FreeBSD jails with full userland-stack and enjail'ed ZFS datasets. The technology works great:
- /etc/rc and /etc/rc.shutdown initialize mutli-user environment
- root user has full control over enjail'ed datasets in the jail: create, mount, destroy, allow...
This may have been around a while but it's the first time I've heard about it. Always interesting to find out about commercial products using FreeBSD.
Looks to be basically 2 servers in a single chassis, with some custom failover functionality. Strange that it talks about dual controller SAS...
I'm running a Freebsd 11.1-RELEASE-p9 NAS with ZFS pool sat comprised of 2 two-way mirrors. The hardware is HP Microserver Gen 8. I have SATA controller set to AHCI mode in BIOS.
mirror-0 disks are ada. mirror-1 disks are ada.
Yesterday I upgraded the iLO (HP name for IPMI)...
I have decided that it's time to try zfs that's why i installed FreeBSD 10.4 with zfs on 2mirrored 1TB sata disks. After playing with zfs i made the mistake of detaching one of the disks from the pool. Now i have two stripe vdevs :
# zpool status
I'm sorry if I don't use the proper ZFS jargon...
I would like to build a "RAID0 (concat)" first, put some data in it, and then build a second "RAID0 (concat)", and then create a "RAID1 (mirror)" in order to have the data on the first RAID0 mirrored to the second one, all of this using...
