zfs

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...

Hello! I have a lot of background info of my setup here, but the short version is: FreeBSD 12.2 server, RAIDZ2 with 5 disks in a RAIDZ2. I just tried to replace drive da0, and now my server won't boot. I'm sure I set this all up wrong, but I hope someone can help me recover. Earlier, I was...

Hello friends, I need to export by NFS the home for a remote server... The creation process was as follows: Create the pool called 'storage' zpool create storage da1 See the pool mounted df -h | egrep 'Filesystem|storage ' Filesystem Size Used Avail...

I've got a machine with one 1TB HD, and I have a spare 3TB HD. In the short-term, but not immediately, I plan to buy a 6–10TB HD, and in the medium-term I think to replace my current 3TB HD with another 6-10TB HD. I want to install FreeBSD with ZFS. What storage layout strategy do you recommend...

Greetings, I have a sort of backup server for snapshots. This server is only dedicated to receive snapshots. There is no NFS/FTP/.... . During a transfer of a snapshot using netcat I added a slog NVMe ssd to the backup pool. I was hoping to see even a tiny speed boost, but there was none. I...

I run an old HP N40L XigmaNAS box with a RAIDZ1 consisting of 3 WD Red 4TB drives. The ada1 drive showed some SMART errors, so I decided to replace that drive. Setting the drive offline, the pool showed the status "DEGRADED" as expected. But after shutting down the system and replacing that...

I have a FreeBSD 13.0 bhyve VM running on a FreeBSD 13.0 host. Originally, The VM was created with a 64 GB disk but I increased that to 128 GB. When logging into the VM, I see that the disk was indeed resized correctly: root@poudriere01:~ # gpart show -lp => 40 268435440 vtbd0 GPT...

Hi All, Hope someone can guide me. I created a zpool called data with 4 pairs of mirrored disks (8 disks in total) mirror-0 to mirror-3 A disk in mirror-0 failed I have been able to remove it from the mirror-0 and replace the disk. This now shows as ada0 in zpool status with no mirror-0 showing...

I'll discard this mobile hard disk drive, but for now: are interface CRC errors more likely to occur with USB, than with IDE? I suspect so … root@mowa219-gjp4-freebsd-d31121-mobile:~ # uptime ; uname -KUv 3:32AM up 1:22, 5 users, load averages: 0.07, 0.12, 0.15 FreeBSD 14.0-CURRENT #0...

Hello, I am not sure what I did, because this computer sits here since 12.1 was new and I was learning at the time. I only boot it once in a month, do backups through LAN, turn it off. Now my problem is this: I wanted to upgrade to 13-RELEASE, but I wanted to do it with boot environments. As I...

I have a Gen8 HP Microserver with 4x 3TB SATA disks attached via AHCI, in a 4 way mirror. I *think* since I upgraded to 13.0 from 12.2 I've been unable to boot from them. I am able to boot successfully from a USB stick with the live image installed. I've reinstalled the 13.0 bootcode on every...

Hi, I've been running Proxmox 6 with ZFS as guest storage for some while now. As guests I have a couple of FreeBSD systems and I plan on expanding the list of FreeBSD guests migrating away from Linux. I once read that it would be counter productive to use ZFS within the FreeBSD guest because...

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...

How to change passphrase for encrypted ZFS disk for FreeBSD 13? I saw this post, but "/boot/encryption.key" is not found. Do I change the passphrase by booting into the disk, or booting into the install-disk? And, if I boot into the install-disk, how do I mount the specific partition to change...

I was having issues keeping the system running. So turned the system off, and ran a memory test, and replaced memory. When I rebooted the pool is unknown, and this is in the log file. Could booting from a CD and Running a memory test mess with the Headers on each drive???? How is that...

Hello, please excuse me if there is already an answer to my question. I could not find one. So far my question is hypothetical. I plan to install FreeBSD on an encrypted and mirrored zroot. But before I do this, I want to make sure that in case of a disk failure, I also know how to repair the...

This is more a trick. The power of mounting nullfs filesystems is underrated. I configured my PC for a separate zfs filesystem /usr/home How to take incremental snapshots ? Incremental snapshots use very little diskspace so you can run them easily every 30 minutes. The script below takes such an...

Why would you encrypt a zfs zvol device with gbde ? Because you can, and it is easy. 1.You stay away from system,boot&root partitions so you don't have boot problems. 2. Most private data is relative small. And fits in one directory with subdirectories. Note : zfs allows encryption by itself but...
