I have a server with IBM ServeRAID 8k-l RAID controller. It has two HDDs in RAID 1 array. After the server reload, IBM ServeRAID 8k-l RAID controller started the rebuild operation for physical drive
# arcconf GETSTATUS 1 Controllers found: 1 Logical device Task: Logical device : 0 Task ID : 101 Current operation : Rebuild Status : In Progress Priority : High Percentage complete : 3 Command completed successfully. #
During that time the virtual machines in this physical server logged file-system related errors. I disabled the physical drive
#1 and thus stopped the rebuilding process and after that, the virtual machines booted up.
Was this an expected behavior? Should the IBM ServeRAID 8k-l RAID controller performance be degraded during the rebuild operation?
