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.
