14 gfs2_convert is used to convert a filesystem from GFS1 to GFS2. It is
15 required that the GFS1 filesystem be checked and fixed for errors using
16 gfs_fsck and that the filesystem be backed up before attempting to con‐
17 vert it. The convert process is irreversible and any error encountered
18 during the conversion can result in the abrupt termination of the pro‐
19 gram and consequently an unusable filesystem. See NOTES section below
20 for more information.

26 This prints out the proper command line usage syntax.
27
28 -q Quiet. Print less information while running.
29
30 -n No to all questions.
31
32 -V Print program Version information only.
33
34 Print out the current version name.
35
36 -v Verbose operation.
37
38 Print more information while running.
39
40 -y Yes to all questions.

42 By specifying this option, gfs2_convert will not prompt before
43 making changes.

47 gfs2_convert /dev/vg0/lvol0
48 This will convert the Global File System on the block device
49 "/dev/vg0/lvol0" to gfs2 format.

53 If gfs2_convert is interrupted for some reason other than a conversion
54 failure, DO NOT run gfs2_fsck on this partially converted filesystem.
55 When this occurs, reissue the gfs2_convert command on the partially
56 converted filesystem to complete the conversion process.
57
58 The GFS2 filesystem does not support Context-Dependent Path Names
59 (CDPNs). gfs2_convert identifies such CDPNs and replaces them with
60 empty directories with the same name. The administrator can use bind
61 mounts on these directories to get the same effect as CDPNs.
62
63 When converting full or nearly full filesystems, it is possible that
64 there won't be enough space available to fit all the GFS2 filesystem
65 data structures. In such cases, the size of all the journals is reduced
66 uniformly such that everything fits in the available space.
