CS407e misaligned partition

Postby leonard_yap » Thu Nov 11, 2010 12:14 pm

Hello,

I think my partition is misaligned, is there anyway to rebuild the RAID with proper alignment without destroying the data?
I noticed the unit to slow down after replacing 2 units of advanced format drives.

Thank you.
