gfs2_convert - Convert a GFS1 filesystem to GFS2
gfs2_convert is used to convert a filesystem from GFS1 to GFS2. It is required
that the GFS1 filesystem be checked and fixed for errors using
and that the filesystem be backed up before attempting to
convert it. The convert process is irreversible and any error encountered
during the conversion can result in the abrupt termination of the program and
consequently an unusable filesystem. See NOTES
section below for more
This prints out the proper command line usage syntax.
- Quiet. Print less information while running.
- No to all questions.
- Print program Version information only.
Print out the current version name.
- Verbose operation.
Print more information while running.
- Yes to all questions.
By specifying this option, gfs2_convert will not prompt before making
- gfs2_convert /dev/vg0/lvol0
- This will convert the Global File System on the block
device "/dev/vg0/lvol0" to gfs2 format.
If gfs2_convert is interrupted for some reason other than a conversion failure,
DO NOT run gfs2_fsck
on this partially converted filesystem. When this
occurs, reissue the gfs2_convert command on the partially converted filesystem
to complete the conversion process.
The GFS2 filesystem does not support Context-Dependent Path Names (CDPNs).
gfs2_convert identifies such CDPNs and replaces them with empty directories
with the same name. The administrator can use bind mounts on these directories
to get the same effect as CDPNs.
When converting full or nearly full filesystems, it is possible that there won't
be enough space available to fit all the GFS2 filesystem data structures. In
such cases, the size of all the journals is reduced uniformly such that
everything fits in the available space.
