i'm facing a problem with my A-class unit and i really need anyone's help.

a couple of days back my head unit reports two dead hard drives and however there are two spare drives , that didn't make any difference. i teried toforce one of them online which was p19 and replaced the other one p12. But , after a while p19 reorted dead again and the rebuild failed .when i tried to put the old p12 in place ,it showed stale state and i tried to clear it with phydrv -a clear staleconfig .

i figured out after that , that i shouldn't do that as now the logical raid reports it missing a hard drive and i'm completely stuck with raid 5 contains one missing and one dead drives.

i'm thinking of completely delete the raid and recreate it with the same hard drives to see if that can help .But for sure any advice would be appreciated .

Hi Mahmoud,

We have replied to the case. Please check.

Since it is RAID 5 array, it cannot afford to have more than 1 bad drive. In your case, PD 12, PD 19 have errors. You have already tried to force online PD 19 but it went offline again becuase of bad sectors.. PD 11 also has lot of errors. So this array is beyond repair becuase of errors on 3 drives.

Thanks !

Hi Mahmoud,

Unfortunartly 2 drive failures on a RAID5 is not recoverable by a rebuild.

But there are many data recovery services who can recover failed drives. Google gives many options.
