  1. ZFS on top enterprise hardware RAID is bad: any evidence or first-hand experience?

    We see everywhere the advice "don't use ZFS on top hardware RAID". But I also see opinions that it's a myth. This question is not about the rationals to avoid (or use) hw raid with ZFS. I'd like to hear from Proxmox community about first-hand experience with ZFS on top hw raid, especially...
  2. MDADM create with NVMe failed - Floating point exception

  3. [SOLVED] ZFS partitions get rebuilt/activated by mdadm

    I have a trouble where mdadm autoactivates zfs volumes from VM's. I would not like mdadm to touch anything from zfs volumes.

  7. Recreating RAIDZ-1 pool to add a disk

  13. [SOLVED] Install Proxmox to SSD and then add another SSD for RAID-1 later?

    I have a server I've installed Proxmox onto that has one SSD for the main system installation. I'd like to add an identical drive in a month to mirror my base install as a software RAID-1 (raidz maybe?) so I don't have any down time for when the primary SSD fails. Can this be done, and if so, how?

    I configured 2 SSDs in RAID1 on my hardware controller. After Proxmox install, the RAID volume shows up as "degraded" (Fig. 1) on the controller. The SMART values (Fig. 2) reflect that one drive is being used but not the other. I had the RAID controller "repair" the degraded mirror, but that...
