I have a virtual machine running on oVirt which is a MDS. I have a mgs
and mdt partition.
ffb11-mgs/mgs 100283136 4096
100276992 1% /lustre/local/mgs
ffb11-mdt0/mdt0 100269952 558976
99708928 1% /lustre/local/mdt0
NAME USED AVAIL REFER MOUNTPOINT
ffb11-mdt0 559M 95.8G 19K /ffb11-mdt0
ffb11-mdt0/mdt0 546M 95.8G 546M /ffb11-mdt0/mdt0
ffb11-mgs 4.13M 96.4G 19K /ffb11-mgs
ffb11-mgs/mgs 3.99M 96.4G 3.99M /ffb11-mgs/mgs
I would like to migrate this virtual machine to another infrastructure.
it is not simple because the other infrastructure is vmware.
what is the best way to migrate those partitions without incurring into
any corruption of data ?
May I simply use zfs send and zfs receive thru SSH ?
what is the best way to move a MDS based virtual machine ?
