Including LKML on this one as it may be a partition size limit? Sdc1 is
not 11TB.

For the second time in two weeks, a system restart has resulted in a
truncated filesystem on my server. The server is running 64bit SuSE with a
fibrechannel connection to a Promise VTrak M500f. The array is populated
with Hitachi 1TB drives. The filesystem should be ~12TB but is only 1.8TB
after the system is brough online.
I have tried to collect the relevant information for diagnosing the
problem. I sought help on #xfs and was referred to the mailing list for
help.
If you can think of any other useflul information please let me know.
