DESCRIPTION
tune2fs
adjusts tunable filesystem parameters on a Linux second extended filesystem.
Never use tune2fs on a read/write mounted filesystem to change parameters!
OPTIONS
- -c max-mount-counts
-
adjust the maximal mounts count between two filesystem checks.
- -e errors-behavior
-
change the behavior of the kernel code when errors are detected.
errors-behavior
can be one of the followings:
continue Continue normal execution.
remount-ro Remount the filesystem read-only.
panic Causes a kernel panic.
- -g group
-
set the user group which can benefit from the reserved blocks.
group
can be a numerical gid or a group name.
- -i interval-between-checks[d|m|w]
-
adjust the maximal time between two filesystem checks.
No postfix or `d' result in days, `m' in months, and `w' in weeks.
A value of zero will disable the timedependent checking.
- -l
-
list the contents of the filesystem superblock.
- -m reserved-blocks-percentage
-
adjust the reserved blocks percentage on the given device.
- -r reserved-blocks-count
-
adjust the reserved blocks count on the given device.
- -u user
-
set the user who can benefit from the reserved blocks.
user
can be a numerical uid or a user name.
