Hi! When I move a VM's storage from `local-lvm` to a TrueNAS Core based ZFS volume over iSCSI, I get the following warning:
Task viewer: VM 102 - Move disk
create full clone of drive scsi0 (local-lvm:vm-102-disk-0)

I placed a VM disk inside this pool and wanted to copy a big repo from a physical machine to the VM (SCSI disk, discard=on,iothread=1,cache=none)
source (physical machine):
tar -cpf - repo | mbuffer -s...
Hello everybody,
Right now I have a 4TB zvol that is attached to a VM that works as a fileserver over NFS/SAMBA. There are some issues with this zvol configuration (mainly related with volblocksize) and I would like to create a new one with the right config to replace the old one.
This zvol is...
Moin,
Ich musste bei allen meinen VMs nachträglich die volblocksize ändern, sowie bei einer Debian-VM die zvols verkleinern und mehrere zvols zu einer einzigen zusammenführen. Dazu habe ich kaum Informationen finden können und es ist mehr sehr schwer gefallen. Als Gedächtnisstütze habe ich mir...
