[Lustre-discuss] How to eliminate an OST from an OSS server

[Mohamed Adel]

Dear,

I have a pre-installed lustre file-system with two MDSs and two OSSs. Each OSS has 6 arrays of disks. 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. Could anyone help me with that or just guide me what should I read to learn how to fix this issue.

Thank you,
