Checking is easy, just run fsck against unmounted file-system.<\/p>\n
# fsck -y \/dev\/sda1\n<\/code><\/pre>\nNow if you want to display some information about the file-system use dumpe2fs commandline tool provided by e2fsprogs package on debian.<\/p>\n
# dumpe2fs -h \/dev\/sda1<\/code><\/pre>\nNote these lines in the output which mention mount count and check?<\/p>\n
Mount count: 43\nMaximum mount count: 50\nLast checked: Fri Mar 25 20:58:32 2016\nCheck interval: 15552000 (6 months)\nNext check after: Wed Sep 21 21:58:32 2016\n<\/code><\/code><\/pre>\nYou can tune those values with tool like tune2fs. Why? For example to trigger file-system check before next mounting or vice versa, to postpone checking. Tune2fs tool is also provided by e2fsprogs package on debian.<\/p>\n
Adjusting maximum mount count before checking to 50 is below. To disable check triggering according to mount count, use “-1” as count.<\/p>\n
# tune2fs -c 50 \/dev\/sda1<\/code><\/pre>\nAdjust maximum check interval to 3 months is below. Use d\/m\/w to set days,months or weeks. To disable check triggering according to interval from last check, use “0” as interval.<\/p>\n
# tune2fs -i 3m \/dev\/sda1<\/code><\/pre>\nTo trigger check on all ext2\/34 file-systems during next reboot use following piece of code. It sets mount count to 9999 on all mounted ext file-systems so it will have to trigger the check unless you have disabled it by setting maximum mount count to 0 or -1.<\/p>\n
for m in ext2 ext3 ext4; do\n for f in `mount -t ${m} |awk '{print $1}'`; do\n tune2fs -C 9999 ${f}\n done\ndone\n<\/code><\/pre>\n
