Package: util-linux Version: 2.25.2-3 Severity: wishlist File: /sbin/fsck Tags: upstream
In the context of #773035, I am looking for a way to figure out whether a reboot *now* would be likely to cause lengthy fsck routine checks, e.g. due to the maximal mount count or days since last check being reached on ext-filesystems. I'd like to avoid parsing debug2fs or tune2fs output and comparing numbers or timestamps in the text output, like /usr/lib/update-notifier/update-motd-fsck-at-reboot seems to be doing on Ubuntu. Instead, I'd really like to just ask fsck. fsck -A -t ext2,ext3,ext4,… -N is already very helpful showing me which filesystem-specific commands it would run, but each of those is run unconditionally on the filesystem and determines by itself whether a check is needed. There is the -n option, and it does seem that the sought information could be parsed from the output, but invoking fsck -n on a mounted filesystem is quite unreliable and it'd be a hack too. So instead, I envision a call such as: fsck -A -t ext2,ext3,ext4,… -q or fsck -q /dev/mapper/vg-root and it would exit 0 if a routine check was not going to happen, and exit non-zero if a check would now happen (possibly encoding the reason in the exit code). -V output could also be provided. Thanks for your consideration. -- System Information: Debian Release: jessie/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.17-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_NZ, LC_CTYPE=en_NZ.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages util-linux depends on: ii initscripts 2.88dsf-58 ii libblkid1 2.25.2-3 ii libc6 2.19-13 ii libmount1 2.25.2-3 ii libncurses5 5.9+20140913-1 ii libpam0g 1.1.8-3.1 ii libselinux1 2.3-2 ii libslang2 2.3.0-2 ii libsmartcols1 2.25.2-3 ii libtinfo5 5.9+20140913-1 ii libuuid1 2.25.2-3 ii lsb-base 4.1+Debian13+nmu1 ii tzdata 2014j-1 ii zlib1g 1:1.2.8.dfsg-2 util-linux recommends no packages.
