.SH DESCRIPTION
|
|
Packit |
6ef888 |
tunegfs2 allows viewing and manipulating the values contained in a
|
|
Packit |
6ef888 |
GFS or GFS2 superblock. It is able to modify the \fIUUID\fR (on GFS2 only),
|
|
Packit |
6ef888 |
\fIlabel\fR, \fIlockproto\fR and \fIlocktable\fR.
|
|
Packit |
6ef888 |
|
|
Packit |
6ef888 |
The values in the GFS2 superblock are read only on mount. Any
|
|
Packit |
6ef888 |
changes on a live filesystem will not take effect until the next
|
|
Packit |
6ef888 |
time it is mounted. Making changes on a live filesystem is not
|
|
Packit |
6ef888 |
recommended for this reason.
