RAID-1 Medium Errors on Both Drives -
Posted on 2014-08-14
Have an SBS-2008 server w an Adaptec 3805 controller and a RAID-1 on the OS and RAID-5 on the "data" volume.
RAID-1 logical device has both drives reporting medium errors and a "bad" stripe condition via Adaptec Storage Manager. RAID status is reporting "OPTIMAL" on this RAID-1, but also reporting the bad stripe condition.
I need to replace drive 1 on this RAID-1 setup, as this one has failed in the past and I think this may be the culprit drive. Not sure if I can fail that drive and not have the logical volume crash on me, since the other drive that will remain online, is having medium errors as well. I'm unsure if during the rebuild process, there might be inconsistencies that will take me down.
I've done a verify/fix operation - ran about an hour and still reports a bad stripe condition. Haven't had a good backup on this server for 5 days now, as the imaging backup program is error'ing out due to the state of this RAID-1.
