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 per-node 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.
