7 tune2fs \- adjust tunable filesystem parameters on second extended filesystems
23 .I interval-between-checks
27 .I reserved-blocks-percentage
31 .I reserved-blocks-count
44 adjusts tunable filesystem parameters on a Linux second extended filesystem.
46 .B Never use tune2fs on a read/write mounted filesystem to change parameters!
50 .I -c max-mount-counts
51 adjust the maximal mounts count between two filesystem checks.
54 change the behavior of the kernel code when errors are detected.
56 can be one of the followings:
58 \ continue\ \ Continue normal execution.
60 \ remount-ro\ Remount the filesystem read-only.
62 \ panic\ \ Causes a kernel panic.
65 set the user group which can benefit from the reserved blocks.
68 can be a numerical gid or a group name.
70 .I -i interval-between-checks[d|m|w]
71 adjust the maximal time between two filesystem checks.
72 No postfix or `d' result in days, `m' in months, and `w' in weeks.
73 A value of zero will disable the timedependent checking.
76 list the contents of the filesystem superblock.
78 .I -m reserved-blocks-percentage
79 adjust the reserved blocks percentage on the given device.
81 .I -r reserved-blocks-count
82 adjust the reserved blocks count on the given device.
85 set the user who can benefit from the reserved blocks.
87 can be a numerical uid or a user name.
90 We didn't find any bugs yet. Perhaps there are bugs but it's unlikely.
93 .B Use this utility on your own risk. You're modifying filesystems.
