[lustre-discuss] migrating MDS to different infrastructure

[Riccardo Veraldi]

Hello,

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 ?

thank you

Rick
