I'm experimenting with various RAID configurations of a new Adaptec 6805 (not the 'E' model) Attached are 8x Hitachi 5400RPM 2TB SATA 6Gb Drives using the miniSAS to SATA cables provided.
I created a RAID6 array comprising four disks, two from each connector. Then I tried expanding the array to the remainder of the disks.
My problem is that raid reconfiguration never seems to progress. After more than 24 hours the Adaptec Storage Manager still shows that it's at 0% completion. I'm not actively using the logical array - so I can't imagine that should be a signficant factor.
- Is this normal for an online reconfiguration?
- Is this indicative of the amount of time it would take to rebuild the array should a drive fail?
- Is it possible to force an offline reconfiguration of the array? Assuming that would speed things up.
Thanks for the responses. Just to clarify - there's no load on the drives, and very little data (~5GB). After about 35 hours it finally showed about 1% - so, I gave up and deleted the array.
My main concern really is: If it takes ~35 hours to do 1%, extrapolating that out means it'd be somewhere around 4-5 months to do a rebuild if a drive failed.
I'll test this out by unplugging a drive and seeing how long it takes to rebuild.
