| Doc Text: |
After the gfs2_grow, gfs2_tool, gfs2_jadd, or gfs2_quota utilities cleaned up the /etc/mtab file, the file's permissions were changed from the default of 644 to 600. As a consequence, non-root processes could not read /etc/mtab. This update fixes the code that cleans up the /etc/mtab file so that it no longer modifies the /etc/mtab file's permissions. As a result, processes are able to access the /etc/mtab file as expected.
