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. It is required that the GFS1 filesystem be checked and fixed for errors
       using fsck.gfs2 and that the filesystem be backed up before attempting to convert it. The convert process is  irreversible  and	any  error
       encountered  during  the conversion can result in the abrupt termination of the program and consequently an unusable filesystem.  See NOTES
       section below for more information.

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.

NOTES

       If gfs2_convert is interrupted for some reason other than a conversion failure, DO NOT run gfs2_fsck on this partially  converted  filesys-
       tem.  When this occurs, reissue the gfs2_convert command on the partially converted filesystem to complete the conversion process.

       The GFS2 filesystem does not support Context-Dependent Path Names (CDPNs).  gfs2_convert identifies such CDPNs and replaces them with empty
       directories with the same name. The administrator can use bind mounts on these directories to get the same effect as CDPNs.

       When converting full or nearly full filesystems, it is possible that there won't be enough space available to fit all the  GFS2	filesystem
       data structures. In such cases, the size of all the journals is reduced uniformly such that everything fits in the available space.
