Quite the opposite. Attempting to shrink filesystem that is already effectively corrupted is potentially dangerous. So the right thing here is to stop md, backup superblocks (in case they will be
I am puzzled. Do I need to backup the raid superblock or the device superblocks or all? How do I backup the superblock? I googled but only find how to recover from superblock backup.
No, sorry, as I said in followup - this was wrong idea. As soon as you changed filesystem on one physical device, you can no more assemble raid again - you really need recreate it, making sure to resync from the correct device. I.e. it would be something like - remove metadata (mdadm --zero-superblock) from both devices - fsck and resize filesystem on one device - create array again (be sure to select correct metadata though) using this device - add second device to resync -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
