Getting ZVOl for VM disk

[chrisu]

Hello,

I am pretty existed about Proxmox and ZFS and finally the ZFS-Support within Proxmox. The lack of missing GUI integration (ZFS command have to be performed by command line, scheduled task like Scrub or status report have to be done by a separate agent) can be well handled by existing How-To's and community threads.
So far have seen that Proxmox creates a ZVOL for every VM-Disk on a ZFS mounted storage. That is really great.
What I am missing is an overview, what ZVOL is assigned what disk? Is there a config files or a command?

Thank you and best greetings

chrisu

Not sure what you need exactly, but we use disk names like "subpool:vm-2000-disk-1", and this maps to zvol "path/to/subpool/vm-2000-disk-1" - so I guess this mapping is quite obvious. You can also use pvesm to get the exact mapping:

# pvesm path subpool:vm-2000-disk-1
/dev/zvol/path/to/subpool/vm-2000-disk-1
