So the exception is generated when mkfs is computing the size of the device.
It could be due to an unexpected value returned by one of the ioctls.
Try this:
# cd /../ocfs2-tools-1.2.1
# ./configure --enable-debug
# make all
# cd mkfs.ocfs2
# gdb ./mkfs.ocfs2
(gdb) set args -b 4K -C 32K -N 4 -L mail_data /dev/etherd/e0.12p1
(gdb) b ocfs2_get_device_sectsize
(gdb) b ocfs2_get_device_size
Set break point at ocfs2_get_device_sectsize() and ocfs2_get_device_size()
and run. See what the sectsize is. Then step thru the code in
get_device_size.
If this is too much, at least generate the coredump and make it available
for download.
Please let me know the results.
Thanks
