Yeah, for all filesystems. It leaves it up to fsck.xfs and fsck.ext3
to decide whether to run the routine check.
And fsck does provide -n, which does help, but it's very brittle:
# fsck -A -t ext2,ext3,ext4,xfs -n 2>/dev/null | grep ': clean,'
root: clean, 10064/121920 files, 114660/487424 blocks
srv: clean, 3062617/9158656 files, 24554289/36620288 blocks
tmp: clean, 16/60928 files, 8235/243712 blocks
usr: clean, 27191/244320 files, 173721/975872 blocks
usr_local: clean, 41/121920 files, 16597/487424 blocks
var: clean, 3485/977280 files, 362495/3905536 blocks
# tune2fs -C 32 /dev/charade/srv
tune2fs 1.42.5 (29-Jul-2012)
Setting current mount count to 32
# fsck -A -t ext2,ext3,ext4,xfs -n 2>/dev/null | grep ': clean,'
root: clean, 10064/121920 files, 114660/487424 blocks
tmp: clean, 16/60928 files, 8235/243712 blocks
usr: clean, 27191/244320 files, 173721/975872 blocks
usr_local: clean, 41/121920 files, 16597/487424 blocks
var: clean, 3485/977280 files, 362495/3905536 blocks
There are two problems here:
1. the last fsck ran a read-only fsck on charade/srv, which took
almost 10 minutes. I can't figure out a way to ask fsck whether
it would run the check, but not actually have it run it.
2. if a filesystem error is detected fsck stops and does not
process the remaining filesystems. I suppose that's not the
worst of it all since at that point you know there must be
a filesystem check, but it would still be useful to know if the
fsck would be required only for a 2G /usr/local volume, or for
a 4Tb /srv filesystem.
