Red Hat Bugzilla – Bug 214621
Allow gfs2_edit to view, print and edit gfs(1) file systems
Last modified: 2009-04-16 18:45:35 EDT
Description of problem:
The current gfs_edit program does not have any capabilities to
print GFS structures or any of the new gfs2_edit features. It would
be nice to allow gfs2_edit be able to distinguish between a gfs1 and
gfs2 file system and be able to view, edit, and print gfs1 data
structures such as the superblock, root directory, rgindex, journal
Version-Release number of selected component (if applicable):
RHEL5 beta 1 with latest cluster software from HEAD
Steps to Reproduce:
1. gfs2_edit /dev/gfs1_vg/gfs1_lvol
gfs2_edit treats a gfs1 fs as if it were gfs2.
gfs2_edit should flag the difference and allow printing of gfs1
data structures (i.e. superblock, directories, etc) when run on
a gfs1 file system.
I've already written changes to do this so I could use the print
function to help in debugging a customer issue involving a gfs1
file system. I just wanted this bugzilla record to document these
Created attachment 140685 [details]
Patch to allow gfs2_edit to operate on gfs1 file systems
Code was committed to cvs for HEAD and RHEL5 that's better than the
previous patch. The previous patch did not correctly identify and
show/print some of the inode information that's changed from gfs1.
Also added a 'c' command to toggle the color scheme. Also added a
few command and parameter synonyms like 'rgindex' for 'rindex' and
-help for -h.
This is much easier than trying to port the missing gfs2_edit
functionality to gfs_edit.
