Hello,
we actually have a storage solution based on a DELL 630 + 3 JBODs
DELL MD 1420 (HBA mode),
The ZFS pool is made of 9 raidz2 vdevs + 1 mirror log + 2 spares
All disks are of the same type in capacity and speed.
The problem is that DELL is unable to provide the SAME kind of disk
(capacity AND speed)
when a disk has to be replaced. So the question is:
Is it possible to replace a 1TB 7200rpm by a 1.2TB 10000rpm disk without
any consequences for the existing pool ?
THanks in advance
Best Regards
JM
