RAID5 Issue

Hello mahmoud.jundi,

You should be ok with the replacement drives you used.  Replace SAS for SAS and same capacity or larger are confirmed.

While it does not happen often, you could have received a drive that was pred fail or near to it and it did go pred fail during the rebuild.

From the description it sounds possible that the array has punctured.

See if you can run a Consistency check on the Virtual Disk from OMSA.

Check the controller log for Puncture

Export the PERC Controller Log via OpenManage Server Administrator

If you do have a puncture: Check the status of your backup. Try to get a file level backup. If you can't get a backup and this is critical information then you may need to engage a data recovery company.

Hello, Many thanks for your reply

I did check the Perc Controller logs and there is no puncture, please check below

What I need is to coordinate with the support to get a brand new Disk and check the status

Thanks again

Hi, based on logs it seems okay to me. I wouldn't expect size cause the issue directly if the same rpm and other features are consistent with lower size drives. At first I would suspect drive failure itself. (In the unlikely event that bad blocks have propagated to other disks, then it may be necessary to create a new RAID and restore backup data again.)

Just curious but by any chance is the part number of the 600GB drive you got W347K?  Those drives have an absolutely insane fail rate so I wouldn't be surprised if it ended up giving you issues that quickly after replacing.

Not sure about part number because the 2nd disk has been replaced today with 300GB, I will check after build and restart the server to see how storage shows in Open Manage

Thank you all , All went well after being replaced by 300 GB and restarted the server

Maybe the 2nd 600 GB was OK but open manage was showing this message "Predicted fail" incorrectly and server should be restarted.
