This morning my Ubuntu server suddenly appeared in read-only mode.
Google says this can happen after updates.
I restarted the server and it booted with fsck errors:
Inodes that were parts of a corrupted orphan linked list found. /dev/mapper/vg0-root: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY fsck died with exit status 4
Google says you can only run
fsck -n on read-only. I will runn that now nd hope to fix the inconstencies.
How can I undo the realy-only mounting of the root file system? Is it safe?
I'm not experienced much in administrating so I'd prefer host support, but it's the holidays...
