In OSS01, one of the arrays is not working properly due to a physical error in one of the disks of the array. I wanted to eliminate this array from OSS01. Simply I restarted MDSs and the OSSs and didn't mount that array. Then I mounted the file-system on the clients. The clients didn't produce any error after mounting but the file-system is not accessible; i.e. I can't even issue an "ls" command to view the contents of the file-system. I need to eliminate that corrupted array to be able to use the file-system but don't know how.

You likely want to deactivate the OST on the MDT and possibly on the
clients also, depending on your goals.

Have you checked the operations manual at
http://wiki.lustre.org/index.php/Lustre_Documentation?

Maybe you did but you just didn't realize "deactivate" was the operation
you were looking to perform.

Cheers,
