tune2fs

adjust ext2/ext3/ext4 filesystem parameters

This call allows you to adjust various filesystem parameters of an ext2/ext3/ext4 filesystem called device.

The optional parameters are:

force Force tune2fs to complete the operation even in the face of errors. This is the same as the tune2fs @-f option.

maxmountcount Set the number of mounts after which the filesystem is checked by e2fsck(8). If this is @0 then the number of mounts is disregarded. This is the same as the tune2fs @-c option.

mountcount Set the number of times the filesystem has been mounted. This is the same as the tune2fs @-C option.

errorbehavior Change the behavior of the kernel code when errors are detected. Possible values currently are: continue , remount-ro, panic. In practice these options don't really make any difference, particularly for write errors.

This is the same as the tune2fs @-e option.

group Set the group which can use reserved filesystem blocks. This is the same as the tune2fs @-g option except that it can only be specified as a number.

intervalbetweenchecks Adjust the maximal time between two filesystem checks (in seconds). If the option is passed as @0 then time-dependent checking is disabled.

This is the same as the tune2fs @-i option.

reservedblockspercentage Set the percentage of the filesystem which may only be allocated by privileged processes. This is the same as the tune2fs @-m option.

lastmounteddirectory Set the last mounted directory. This is the same as the tune2fs @-M option.

reservedblockscount Set the number of reserved filesystem blocks. This is the same as the tune2fs @-r option. user Set the user who can use the reserved filesystem blocks. This is the same as the tune2fs @-u option except that it can only be specified as a number.

To get the current values of filesystem parameters, see tune2fs_l. For precise details of how tune2fs works, see the tune2fs(8) man page.
