How long to add 2x300GB SAS disks to RAID5 MSA2000 array?
I need to add a couple of disks to a RAID5 vdisk on an MSA2312i. I've read that it can take a long time. The new disks are actually in a RAID1 vdisk at the moment which I'll drop and add to the RAID5 instead (currently has 4 x 300GB disks). What I'm trying to work out is:
1. How long??? Some estimates sound insane - 4 days or more??
2. Is the array accessible during this time?
3. If so, how badly is performance degraded
