    Why is `ZFS over iSCSI` clones support limited?

    Why are clones not supported when using `ZFS over iSCSI`? Refer to table in: https://pve.proxmox.com/wiki/Storage:_ZFS_over_ISCSI In contrast, NFS has support for clones via qcow2. https://pve.proxmox.com/wiki/Storage:_NFS

    pve-zsync: still supported?

    As part of investigating different options for ZFS dataset replication under proxmox, I've comes across a tool called `pve-zsync`.This appears to be for syncing zfs datasets between hosts, a bit like how `pvesr` syncs the zfs disk images between hosts. I'm struggling to understand if `pve-zsync`...

    Cloning from ZFS snapshot in GUI

    Hi all, We're running into a limitation in the GUI when trying to clone a vm from a snapshot on ZFS storage. On LVM this works fine, I know this works a bit different and also allows for non-linear snapshots which ZFS doesn't. A full clone however should be possible in my AFAIK. I'm able to...

    Failing SSD in ZFS RAID1 - How to replace SSD

    I rebooted one of my HA boxes over the weekend, and a message popped up at the BIOS level that one of the 2 SSD drives is 'near life end'. The system has 2x240GB SSD drives in a ZFS RAID 1 (created during install by Proxmox). The mfg. is sending me a new drive (actually 2) as they appear to be...

    Optiming Virtual Disk Volume Block Size (Host) and EXT4 Blocks/Groups (Guest)

    It just occurred to me that the Reason why I'm getting such a MASSIVE overhead on my Backup Server (which has 2 x RAIDZ-2 x 6 Disks each) is because the Default ZVOL on Proxmox VE is (or probably "was" for a long Time, and many of my Virtual Disks are quite Old) 8k, which results in a Space...

Also when I list the snapshots using zfs list -t snap, they are still all present, even with the correct...

    I want to re-install proxmox from scratch, but use another two disks in a zfs mirror on the same machine. While installing, it tells me that there is already a zpool "rpool" and therefore I cannot install proxmox. Anyway, I chose to rename the pool to something like...

    HW RAID or ZFS on Dell PowerEdge R630

    Hi, I am wondering whether this is a correct usage of my hardware which runs PVE. I have a Dell PowerEdge R630, 2x HDDs, and 2 SSDs. From what I understand, ZFS is not recommended to run on hardware RAID. The controller (PERC H730 Mini) is currently set to HBA mode and I configured the Proxmox...
