Opcje wykonania tune2fs w konsoli

-c max-mount-counts

Specify the maximum number of mount counts between two checks on the filesystem.

 -C mount-count

Specify the mount count. For use with -c to force a check the next time the system boots.

 -e behavior

Specify the kernel's behavior when encountering errors. behavior must be one of:

continue

Continue as usual.

 remount-ro

Remount the offending filesystem in read-only mode.

 panic

Cause a kernel panic.
-f

Force completion even if there are errors.

 -g group

Allow group (a group ID or name) to use reserved blocks.

 -i interval[d|w|m]

Specify the maximum interval between filesystem checks. Units may be in days (d), weeks (w), or months (m). If interval is 0, checking will not be time-dependent.

 -j

Add an ext3 journal to the filesystem. If specified without -J, use the default journal parameters.

 -J jrnl-options

Specify ext3 journal parameters as a comma-separated list of option=value pairs. The specified options override the default values. Only one size or device option can be specified for a filesystem. Possible options are:

device=ext-jrnl

Attach to the journal block device on ext-jrnl, which must exist and must have the same block size as the filesystem to be journaled. ext-jrnl can be specified by its device name, by the volume label (LABEL=label), or by the Universal Unique Identifier (UUID) stored in the journal's ext2 superblock (UUID=uuid; see uuidgen). Create the external journal with:

mke2fs -O jrnl-dev ext-jrnl

size=jrnl-size

The size of the journal in megabytes. The size must be at least equivalent to 1024 blocks and not more than 102,400 blocks.
-l

Display a list of the superblock's contents.

 -L label

Specify the volume label of filesystem. The label must be no more than 16 characters.

 -m percentage

Specify the percentage of blocks that will be reserved for use by privileged users.

 -M dir

Specify the filesystem's last-mounted directory.

 -o mount-options

Set or clear the specified default mount-options. Mount options specified in /etc/fstab or on the command line for mount will override these defaults. Specify multiple options as a comma-separated list. Prefixing an option with a caret (^) clears the option. No prefix or a plus sign (+) causes the option to be set. The following options can be cleared or set:

acl

Enable Posix Acess Control Lists.

 bsdgroups

Assign new files the group-id of the directory in which they are created instead of the group-id of the process creating them.

 debug

Enable debugging code.

 journal_data

When journaling, commit all data to journal before writing to the filesystem.

 journal_data_ordered

When journaling, force data to the filesystem before committing metadata to the journal.

 journal_data_writeback

When journaling, force data to the filesystem after committing metadata to the journal.
-O option

Set or clear the specified filesystem options in the filesystem's superblock. Specify multiple options as a comma-separated list. Prefixing an option with a caret (^) clears the option. No prefix or a plus sign (+) causes the option to be set. Run e2fsck after changing filetype or sparse_super. The following options can be cleared or set:

dir_index

Use B-trees to speed up lookups on large directories.

 filetype

Save file type information in directory entries.

 has_journal

Create an ext3 journal. Same as the -j option.

 sparse_super

Save space on large filesystems by limiting the number of backup superblocks. Same as -s.
-r num

Specify the number of blocks that will be reserved for use by privileged users.

 -s [0|1]

Turn the sparse superblock feature on or off. Run e2fsck after changing this feature.

 -T time

Set the time e2fsck was last run. The time specification is international date format, with the time optional—i.e., YYYYMMDD[[HHMM] SS] . If time is specified as time-last-checked, the current time is used.

 -u user

Allow user (a user ID or name) to use reserved blocks.

 -U uuid

Set the UUID of the filesystem to a UUID generated by uuidgen or to one of the following:

clear

Clear the existing UUID.

 random

Randomly generate a new UUID.

 time

Generate a new time-based UUID.
