    Helpful hints for users moving from TrueNAS Scale to Proxmox (zfs, Samba/SMB share)

    As a new user to proxmox (coming from TrueNAS Scale), I made a bunch of mistakes that cost me an aggravating week of time/effort.

    ZFS - How do I stop resilvering a degraded drive and replace it with a cold spare?

    Replacement HDD gets here tomorrow. In the mean time I'd like to save the mirrored good drive from working overtime to resilver the failing drive. I also don't understand how to swap the new drive with the old drive, since I don't have any open drive bays to add the new drive to the pool...

    Ditching Unraid in favor of Proxmox for ZFS storage shares?

    Hi there, I'm currently running Unraid in a VM on Proxmox and passing through the SATA controllers, as well as one NVME drive on my Motherboard. I started using Unraid as an easy method to use disks of different sizes and have a cache in front. But over time, came to realize that the vanilla...

    Inconsistent file copy on Windows + ZFS

    We have recently run up against an issue where large (>4GB) copies cause lockups within a Windows guest. These can be copies within the same folder, or across disks. The original issue was seen on a RAID Z-1 pool (6x 870 EVO SSD), but has been replicated on ZFS RAID-1 pool with Micron 7450. The...

    HPE P816i-a SR Gen 10 - SCSI Resets and ZFS failures

    Hi everyone, i have a kind of weird behaviour with a PBS based on a HP DL380 Gen10. Since the upgrade to PBS 4 the system sporadically "spits out" one of 10 SAS disks. Interestingly enough its a different disk every time and it's mostly just one. These disks get marked as failed in the ZFS...

    random kernel hang in zfs

    Hi, We have a proxmox 8.3 host running on a fujitsu Primergy RX2540 M4 server. It's running zfs on top of hw raid which I know is not recommended, but I don't think it should lead to this behavior. It has crashed three times during the last 4 months. I was only able to capture the call trace...
