Updating a mirrored zpool with larger disks, one at a time. Got about halfway through when the server unexpectedly rebooted (still unknown why, but that's beside the point). The device labels (/dev/daX) were reshuffled, but I'm manually assigning zfs labels so it shouldn't have been an...

Hello forum. So, a few weeks ago I updated my Latitude5400 from 13.3 to 14.1. A couple of days later I discovered (by running # zpool status) that my zroot pool had a upgrade available. Like a ignorant f..ker I just ran # zpool upgrade zroot expecting that would be the only thing I needed to...

Hi, Currently I have a zpool that does not work anymore. The name of the pool is zroot. The VM was running in FreeBSD version 14.1 and got in a faulty state when the host hang. ZFS is always better then no ZFS (Dan Langeville), I would like to learn from this broken state. The gpart show...

first part of my zpool administration infographics is ready, i hope it helps. modified as per suggestions..

I am having issues with my upgrade to 13.2 from 12.4 and would like to revert to my previous version of FreeBSD for note-taking and attempting a new update from scratch as I cannot get my jails to run, I cannot get VNC or Xrdp to run at startup. I am a little gun shy as I am not sure why my new...

Title: zpool name change from default (Causes Errors post_install), Virtualized in VirtualBox 7.0 Debian-12.1.0-amd64 - FreeBSD 14.0-RELEASE-amd64 Guest O/S Hey everyone! My production server has been offline for over 1 year now due to unlawful Compromising. (Besides that _Fact_), I am...

Dear Everyone, The release notes for 14.0-RELEASE state, "After a system upgrade, but before doing a zpool upgrade, the boot loader on the ESP must be updated, or the system may become unbootable." My question, in great brevity, is, "How?" (when the system is purely UEFI GPT) Having looked at...

Scenario: There are five vdevs that are SATA Hard Disks. The array is fully operational and online. The file systems are mounted, but there is little activity besides the typical programs expected on a FreeBSD machine. I remove one disk. Is there ever a point where the disk becomes so out of...

Looking for help with ZFS. I am booted into a live FreeBSD 13.2 trying to fix my zroot. Zpool import returns ZFS filesystem version: 5 ZFS storage pool version: feature support (5000) pool: zroot id: 8141163279847660127 state: online Status: some supported features are not enabled on the pool...

I have a server with a mix of pools ssd & SATA disks, I started to notice that the server began to reboot frequently, I manage to boot in single mode, and notice that no more reboots, then I boot the pool with the oldest SATA disks and after a while, it restarted (no logs in console) also no...

I've noticed that having torrented files (OS images, etc) download directly to the storage zpool can really slow down reads from the pool. Pausing the download software during sustained read events temporarily resolves the issue, but isn't really something I can do regularly. I have a spare SSD...

Hey everyone I have a zpool in raidz2 configuration. One of the drives faulted, so I took it offline and replaced the drive in the space. Now I'm trying to zpool replace {poolname} /dev/ada0 and I'm getting cannot zero first 4096 bytes of '/dev/ada0': Input/output error. Taking a look at...

Due to unknown to me reasons I'm having issues while importing a zpool (RAID 0, two disks). Whenever I issue the command the system crashes and reboots showing this error: The only way I can successfully import the zpool (but don't know how to access the data in it) is when I connect the...

man for gptzfsbool says "The first pool seen during probing is used as a default boot pool." Is there any way to boot from another pool?

Hello) Now i have raidz1 of 4x3tb disks. I want to upgrade it to raidz2 6x6tb disks. 3tb disks are good and functional, and i want to use them in new array. Is there a way to make 2x3tb disks to be 6tb member of raidz2? man says: Virtual devices cannot be nested, so a mirror or raidz virtual...

One of two hard discs (ada1) in a zpool mirror started to fail today, so I used a spare disc to try to replace the disk. I used gpart to create partitions of identical sizes and a boot section to the ok disc (ada0) and successfully got it in with zpool attach. In the midst of the resilvering...

Hi, after reboot I was surprised with a "no pools available to import" error during boottime, leaving my system stuck with a failed /etc/rc script. I have only one zpool, geli encrypted, pretty much the defaults zfs settings on install. The problem does not exist in single-user mode and I am...

Hi Everyone, I've started to use ZFS instead of the venerable UFS and would like to clarify some points about vdevs and zpools. My understanding is that the primary purpose of vdevs is to allow the combination of several disks to be used as a single virtual disk, and the primary purpose of...
