Holger had the idea to add to molly-guard a check that would require
the sysadmin to manually ack a reboot if fsck would be expected to
run. I like it.
Instead of parsing df -t output, invoking tune2fs -l and doing
a whole bunch of grep magic, I wonder if there's a smarter way to
find out if fsck would do something if it were to run now.
There is
fsck -A -t ext2,ext3,ext4,… ...
but I could not find out how to ask it the question I want answered,
which is: "hey, fsck, if you were to run right now on -All
filesystems of -type as listed, would you want to do a routine
check?"
Do you know?
Cheers,
Per man fsck ...
*-N*Don't execute, just show what would be done.
Which, unfortunately, always outputs one line:
fsck from util-linux-ng 2.17.2
... but then lists the fs-specific fscks that it would run ..
[/sbin/fsck.xfs (1) -- /] fsck.xfs /dev/md0
[/sbin/fsck.ext3 (1) -- /boot] fsck.ext3 /dev/sda1
My apologies. This obviously fails to address your requirement at all.
Seem to be suffering from total lack of reading comprehension this
morning :-(
