Does GFS 6.1 have any superblock backups a la ext2/3? If so, how

Unfortunately, no.
If that is the case, then is it safe to assume that fs_sb_format will
always be bytes 0x1001a and 0x100b on a gfs logical volume, and that that
is the only location on the lv that it is stored? I see
#define GFS_FORMAT_FS (1309) /* Filesystem (all-encompassing) */
and that is the location that where I see 0x051d (1309) stored.
Yes .. in theory (since I don't have the source code in front of me at
this moment).
Thinking to hand patch it, don't you ? ... There is a header file (I
think it is gfs_ondisk.h) that describes the super block layout.
