ZFS management leaves much to be desired (Proxmox 6.2)

[MoxProxxer]

ZFS creation is a blind shot in the dark:



Ok - shell, here I come:

# /sbin/zpool create -o 'ashift=12' space2 raidz /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BN0X /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242EM2 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242D0Q /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21AXN7 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21CPM7 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242AYT /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BQ5B /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242CZN /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21D3RL /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BPLS /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242E7X /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA23WAED

Ah - at least we see the reason and not just an "exit code 1". Ok, have it your way, zpool:

# /sbin/zpool create -f -o 'ashift=12' space2 raidz /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BN0X /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242EM2 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242D0Q /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21AXN7 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21CPM7 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242AYT /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BQ5B /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242CZN /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21D3RL /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BPLS /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242E7X /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA23WAED
cannot create 'space2': invalid argument for this pool operation

Goddamit.

# /sbin/zpool create -fd space2 -o 'ashift=12' raidz /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BN0X /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242EM2 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242D0Q /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21AXN7 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21CPM7 /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242AYT /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BQ5B /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242CZN /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21D3RL /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA21BPLS /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA242E7X /dev/disk/by-id/ata-ST10000VN0004-1ZD101_ZA23WAED

Hallelujah! (Observe the "d" in -fd) and the args reorg.

All in all, ZFS deletion, migration, growth, shrink support in Proxmox: an estimated 2% out of 100% ;-)

ZFS creation is a blind shot in the dark:

When the error window pops up, a bright red error message appears in the task log, too.


You can double click it and it will contain all the output that you got later ("contains a filesystem..."). If there is an error about existing filesystems, you can also try wipefs -a <disk>. Helpful not only for ZFS.

What version of Proxmox VE do you use pveversion -v? Using -f like you initially did worked flawlessly for me.

Additionally, you're always free to post an enhancement request at bugzilla.proxmox.com.
