gfs2_convert(8)
NAME
gfs2_convert - Convert a GFS1 filesystem to GFS2
SYNOPSIS
gfs2_convert [OPTION]... DEVICE
DESCRIPTION
gfs2_convert is used to convert a filesystem from GFS1 to GFS2. Do not
attempt to convert a GFS1 filesystem which is not clean - the process
of conversion will reinitialise the journals. We highly recommend that
fsck.gfs is run successfully before attempting to convert a filesystem.
Many of the on-disk structures are identical between GFS1 and GFS2, so
the conversion process updates the journals, a few items of incompatible metadata (mostly indirect pointers and inodes) and adds the pernode directories required by the gfs2meta filesystem. The conversion
process is performed in-place and does not require any extra disk space
so that it is possible to successfully convert a GFS1 filesystem that
is completely full.
Always ensure you have a complete backup of the data on any filesystem
before starting the conversion process.
