gfs2_convert(8) System Manager's Manual 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 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.
OPTIONS
-h Help.
This prints out the proper command line usage syntax.
-q Quiet. Print less information while running.
-n No to all questions.
-V Print program Version information only.
Print out the current version name.
-v Verbose operation.
Print more information while running.
-y Yes to all questions.
By specifying this option, gfs2_convert will not prompt before making changes.
EXAMPLE
gfs2_convert /dev/vg0/lvol0
This will convert the Global File System on the block device "/dev/vg0/lvol0" to gfs2 format.
