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
       fsck.gfs2  on  this  partially  converted  filesystem.   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.

                                                                                  gfs2_convert(8)
