Hi,

a colleague recently tried to grow a 16 TB filesystem (x86, 32bit) on
top of lvm2 to 17TB. (I am not even sure if that's supposed work with
linux-2.6, 32bit)

used kernel seems to be debian sarge's 2.6.8

xfs_growfs seemed to succeed (AFAIK..)

however, the fs shut down:

and finally, xfs_repair stops at

bad primary superblock: inconsistent file geometrie information

found candidate secondary superblock...
superblock read failed, offset 10093861404672, size 2048, ag 0, rval 29

thanks in advance,
