Unable to create ZFS pool

[PopeFelix]

Running openmediavault-zfs v7.1 on OpenMediaVault 7 hosted on a Proxmox (QEMU) VM. When I attempt to create a ZFS pool via the GUI I get the following error message:

 500 - Internal Server Error
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; ls -la /dev/disk/by-id | grep 'sdb$'' with exit code '1': 

Output of lsblk:

sda      8:0    0   32G  0 disk 
├─sda1   8:1    0   31G  0 part /

└─sda5   8:5    0  975M  0 part [SWAP]

sdf      8:80   0  1.8T  0 disk 
sr0     11:0    1  631M  0 rom  

I'm trying to create a RAIDZ1 pool with /dev/sdb, /dev/sdc, /dev/sdd, /dev/sde, and /dev/sdf. Setting the "Force creation" flag doesn't help.

OK, I see why this is happening. /dev/disk/by-id is not listing all of the disks that lsblk is. Maybe I've passed the disks through from proxmox wrong.

This is pretty clearly a problem on my end, and not OMV, but I'm going to leave this up in case the devs here have any suggestions.

You cannot use by-id on kvm VMs because there is no id for the virtual disks (by default). Unfortunately, the plugin can't change this. I use the 'none' device alias when working on a kvm VM.

"I use the 'none' device alias when working on a kvm VM." - Would you elaborate on that, please?

[ryecoaaron]

When creating a pool, there is a field called "Device alias". Set it to none.
