RAID-10 initialization taking between 30 - 40 hours to complete
Posted on 2008-10-01
Dell PE 2950 III with PERC 6/i. Building a RAID-10 array, 4 drives, total 738 GB capacity.
After defining the virtual disk using the PERC 6/i BIOS menus, PERC 6/i began a "Back Init" operating for the RAID-10 virtual disk.
That process has been going on for over 20 hours and it is still only at 57%.
Is this typical when initializing a RAID-10 virtual disk?
I've initialized RAID-1 and RAID-5 virtual disks in the past on the same hardware, and they only took between 30 - 80 minutes to initialize, even with large size virtual disks (For instance a 1TB RAID-5 VD took about an hour or so to initialize).
So I'm trying to determine whether it's standard for RAID-10 virtual disks to take this long to initialize, or if there's some type of underlying isssue here that I need to investigate further.
Under Operation, PERC is saying "Back Init". Usually when initializing
a virtual disk, it just says "Init".
So I'm not sure what "Back Init" is all about. I've scoured the PERC 6/i
documentation and I have found no mention of "Back Init" versus "Init".
