NAME

tunegfs2 - View and manipulate gfs2 superblocks

SYNOPSIS

tunegfs2 [ OPTIONS ] /dev/blockdevice

DESCRIPTION

tunegfs2 allows viewing and manipulating the values contained in a GFS or GFS2 superblock. It is able to modify the UUID (on GFS2 only), label , lockproto and locktable .

The values in the GFS2 superblock are read only on mount. Any changes on a live filesystem will not take effect until the next time it is mounted. Making changes on a live filesystem is not recommended for this reason.

OPTIONS

-h

Prints out usage information for this command.

-l

List contents of the filesystem superblock. Includes the current values of the parameters that can be set by this program.

-L <label>

Change the filesystem label. Note that the GFS2 filesystem label is also the locktable name.

-o [lockproto=<proto>] [locktable=<table>]

Set mount options. Currently supported options include lockproto and locktable

-U <uuid>

Set the filesystem UUID

-V

Print out the information on the version of the tool.

-r <version>

Set the filesystem format version.
