| .SH DESCRIPTION |
| .BI tune2fs |
| adjusts tunable filesystem parameters on a Linux second extended filesystem. |
| .PP |
| .B Never use tune2fs on a read/write mounted filesystem to change parameters! |
| .PP |
| .SH OPTIONS |
| .TP |
| .I -c max-mount-counts |
| adjust the maximal mounts count between two filesystem checks. |
| .TP |
| .I -e errors-behavior |
| change the behavior of the kernel code when errors are detected. |
| .I errors-behavior |
| can be one of the followings: |
| .br |
| \ continue\ \ Continue normal execution. |
| .br |
| \ remount-ro\ Remount the filesystem read-only. |
| .br |
| \ panic\ \ Causes a kernel panic. |
| .TP |
| .I -g group |
| set the user group which can benefit from the reserved blocks. |
| .br |
| .I group |
| can be a numerical gid or a group name. |
| .TP |
| .I -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. |
| .TP |
| .I -l |
| list the contents of the filesystem superblock. |
| .TP |
| .I -m reserved-blocks-percentage |
| adjust the reserved blocks percentage on the given device. |
| .TP |
| .I -r reserved-blocks-count |
| adjust the reserved blocks count on the given device. |
| .TP |
| .I -u user |
| set the user who can benefit from the reserved blocks. |
| .I user |
| can be a numerical uid or a user name. |
