Hi, That would be dangerous. I would hope that the resource groups would be ignored, but I've never done it. I wouldn't be surprised if you had gfs2_edit segfault for some of it. At the very least, you would be turning all your journal blocks to appear like dinodes, as well as all the extended attributes, directory leaf blocks, etc., which will confuse fsck.gfs2. The fsck.gfs2 will do a much better job if you only change the dinode blocks from 0 to 3. You would be much better off writing a loop that first checked the block's current type, with -p <block number> blocktype, and only change its bit to 3 if it is type 4 (dinode). Also, the script would take a very long time, because it's going to invoke gfs2_edit a trillion and a half times. Writing a program to do this once would be quicker.
