Re: Filesystem gone readonly



Hi, Hiren,

I agree with Christian, before running fsck, you should have a look on the hardware status. If it's not a file system issue, running fsck may cause terrible amount of files lost.
Additionally, you need to create a backup with the help of dd before any fsck, so that you are able to recover some lost files.

Good luck,

Is there any chance that some other node on the san has this lun
mounted, or is writing to it?
