    Solved ZFS single root fs

    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...

    ZFS ZFS boot problem after upgrade to 13.0

    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...

    proxmox Running FreeBSD as a virtual guest with ZFS

    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...

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...

    ZFS Woke up to drive pool not found this morning. At a loss as to what to do? Any suggestions would be welcomed!

    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...

    ZFS Replacement of a hard disk in a mirrored, encrypted (geli) root pool

    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...

    Backup userdata & etc config data in one go.

    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...

    Encrypting a zfs zvol device with gbde

    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...

    ZFS ZFS and Hotswap Indicator LEDs?

    This may be a dumb question, but when a hotswap drive in a server fails under ZFS does the LED indicating a drive failure come on for that drive? Another question: can hotswap drives simply be replaced under ZFS to have it handle replicating the data, or are manual actions required within the...

    ZFS Root on ZFS and backups.

    Hi all, If I have a root on ZFS pool, it is my understanding that if I zfs send the ZFS pool to some location, then the entire pool is backed up to that location, but that backup cannot be restored to root with zfs recv.
