Hello,

I have a Proxmox 3.4 host, and for some reason, I can't create a simple zfs mirror. Here's what I'm trying to do.

Code: 
zpool create -f -o ashift=12 datastore mirror /dev/disk/by-id/ata-Crucial_CT256MX100SSD1_14330CEDCBB5 /dev/disk/by-id/ata-Crucial_CT256MX100SSD1_14290CA27F0F log /dev/disk/by-id/ata-INTEL_SSDSC2BA100G3_BTTV3354065M100FGN

When I enter this, I always receive this error.
Code: 
[SIZE=1]cannot create 'datastore': invalid argument for this pool operation
[/SIZE]

This 3.4 install was a fresh install. All the libraries seem to be installed, and loading.

Code: 
[SIZE=1]root@proxmox2:~# dmesg | grep -E 'SPL:|ZFS:'
[   12.391091] SPL: Loaded module v0.6.4.1-1
[   12.866580] ZFS: Loaded module v0.6.4.1-1, ZFS pool version 5000, ZFS filesystem version 5
[   15.193521] SPL: using hostid 0xa8c00802
[/SIZE]

Code: 
[SIZE=1]root@proxmox2:~# dpkg -l | grep zfs

Any ideas to get this working are appreciated.



 
Thanks for the reply, but this is a host that I've been running for a while now. I have restarted a few times already trying to get this to work. I use the pve test 3.10 kernel if that makes any difference.
 
And are you sure that the "zpool" command is the same version as the kernel modules? All the searches for your error point to different versions. Did you install ZoL from Proxmox repos or from zfsonlinux.org site?

Everything is stock Proxmox. I haven't install anything from the zfsonlinux site. A few weeks ago I setup a small pool of SSDs to temporarily, so this used to work (I used zpool destroy to remove the unused pool a few days ago). Unfortunately, I can't create new pools anymore.
 
Try to create the pool using a single SSD first (or 3 pools using each SSD) to make sure that the drives and paths are OK.

Another attempt would be to reinstall Proxmox ZFS related packages to make sure they are in sync (yes I know I'm pressing this, but that's what ZoL issues list say).
