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.
