Hi !
(I'm on Ubuntu 7.10 64 bits)
I have array of 12 750gb disks in hardware Raid 6 that gives me a 7Tb
partition. I tried to format it in ext3, but it took too much time, so I
tried in Reiserfs, but the partition were lost on reboot, and now i'm
trying XFS.
So I created the partition with parted, because fdisk can't do more that
2tb partitions.
It's ok, I can do what I want but...
on reboot, there is a Superblock problem, something like that. When I
check with xfs_check :
xfs_check: unexpected XFS SB magic number 0x00000000
xfs_check: read failed: Invalid argument
xfs_check: data size check failed
cache_node_purge: refcount was 1, not zero (node=0x681420)
xfs_check: cannot read root inode (22)
bad superblock magic number 0, giving up
So, I tried to delete the partition with parted, to recreate a new one.
No problem. But when I mount the new partition, all the data that were
on my deleted partition are there !!! That's of course not a problem,
but I'm wondering if there's a way to have this partition work directly
without having to delete and recreate it ?
I checked the /proc/partition before and after doing parted :
BEFORE
major minor #blocks name

105 0 7325417080 cciss/c1d0
105 1 [B]7325417046[/B] cciss/c1d0p1
So, any idea what I could do ?
Thanks a lot
