Re: 7Tb XFS partition lost on reboot

Ok, sorry for the mix-up.
You were right, the problem was about the partition table.
Actually, even if it was a gpt partition table, it was corrupted. I 
seems to be a ubuntu parted problem. I had to rebuild pared from the 
sources and when I ran it, it said :

# ./parted
GNU Parted 1.8.8
Using /dev/cciss/c1d0
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print                                                           
print
Warning: /dev/cciss/c1d0 contains GPT signatures, indicating that it has 
a GPT
table.  However, it does not have a valid fake msdos partition table, as it
should.  Perhaps it was corrupted -- possibly by a program that doesn't
understand GPT partition tables.  Or perhaps you deleted the GPT table, 
and are
now using an msdos partition table.  Is this a GPT partition table?
Yes/No? yes                                                              
yes
Model: Compaq Smart Array (cpqarray)
Disk /dev/cciss/c1d0: 7501GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End     Size    File system  Name     Flags
 1      17.4kB  7501GB  7501GB  xfs          primary      



So I deleted the existing partition and recreated a new one. I found 
back all my data on this new partition, and on reboot there is no 
problem anymore.

Thanks a lot for your help ! :)
