gfs2_convert - Convert a GFS1 filesystem to GFS2
gfs2_convert is used to convert a filesystem from GFS1 to GFS2. It isrequired that the GFS1 filesystem be checked and fixed for errors using fsck.gfs2
and that the filesystem be backed up beforeattempting to convert it. The convert process is irreversible and anyerror encountered during the conversion can result in the abrupttermination of the program and consequently an unusable filesystem.See NOTES
section below for more information.
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 makingchanges.
- 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 convertedfilesystem 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 therewon't be enough space available to fit all the GFS2 filesystem data structures. In such cases, the size of all the journals is reduced uniformlysuch that everything fits in the available space.
