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 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)
