(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 104 0 35532720 cciss/c0d0 104 1 34025638 cciss/c0d0p1 104 2 1 cciss/c0d0p2 104 5 1502046 cciss/c0d0p5 105 0 7325417080 cciss/c1d0 105 1 [B]882966102[/B] cciss/c1d0p1 AFTER major minor #blocks name 104 0 35532720 cciss/c0d0 104 1 34025638 cciss/c0d0p1 104 2 1 cciss/c0d0p2 104 5 1502046 cciss/c0d0p5 105 0 7325417080 cciss/c1d0 105 1 [B]7325417046[/B] cciss/c1d0p1 So, any idea what I could do ?
