We have a PS6500e that lost power to two out of three power supplies. It went in the standby mode before power was restored. Now it's back up but all the mounted volumes are read-only. When I try to remount I see the following message:
mount: cannot remount block device /dev/mapper/eql-0-8a0906-74a43a805-a690018d58c53dd8-ps6500e-vol2 read-write, is write-protected
I don't see anything relevant in the group manager GUI either. How do I switch these filesystems to the rw mode?
Solved! Go to Solution.
It's not likely on the array. When the array went down, Linux received a SCSI error and commands timed out. It will remount the volume RO. I have seen cases where the re-mount option does not work in such cases. Either unmount and remount it manually or reboot the host.
