.SH NAME
gfs2_convert - Convert a GFS1 filesystem to GFS2

.SH SYNOPSIS
.B gfs2_convert
[\fIOPTION\fR]... \fIDEVICE\fR

.SH DESCRIPTION
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 
\fBfsck.gfs2\fP 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 \fBNOTES\fP section below for more information.

.SH EXAMPLE
.TP
gfs2_convert /dev/vg0/lvol0
This will convert the Global File System on the block device
"/dev/vg0/lvol0" to gfs2 format.

.SH NOTES
If gfs2_convert is interrupted for some reason other than a conversion 
failure, DO NOT run \fBfsck.gfs2\fP 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.
