I have following case: Server with 4 disks - devices /dev/sdb
- /dev/sde
.
Each of these disks is physical volume, and all of them are within single volume group.
In this volume group, I have single logical volume, that spans across all 4 disks.
Now, I want to migrate it to larger disks. I added 4 new drives (/dev/sdf - /dev/sdi)
, and will move data.
Normally I would:
pvmove /dev/sdb /dev/sdf
wait for it to finish
pvmove /dev/sdc /dev/sdg
wait for it to finish
pvmove /dev/sde /dev/sdi
The question is - can I safely run all 4 pvmoves at the same time, without waiting for each of them to finish?
