OK.

# libtool gdb parted
(gdb) set args [the lv device]
(gdb) run
(parted) CTRL-C
(gdb) break _ext2_resize
(gdb) break ext2_resize_fs
(gdb) cont
(parted) resize ...
(gdb) print *(fs->geom)
(gdb) print *geom
(gdb) cont
(gdb) tbreak 111
(gdb) print fs->sb.s_blocks_count
(gdb) cont
(gdb) tbreak 111
(gdb) print fs->sb.s_blocks_count
(gdb) cont

[repeat until bored]

(gdb) cont
(parted) quit

Thanks,
