I have a dual opteron SuSE 9 SLES machine running 2.6.9 kernel. The
machine has 2 3ware 9500-12 PCI-X SATA raid cards installed with 12
250 GB drives on each card.

I can create the partitions using parted & when I mount the two
partitions they show up correctly as 2.6 TB each and they seem to be
working perfectly. When I reboot the system I get the error:
kernel:XFS:size check 2 failed in the kernel log and the mount command
came back bad superblock on /dev/sdb1. I can no longer mount the
drives. I tried doing a xfs_repair to fix the drive and I can mount
it again, but it only shows up as 513GB after that. Then I have to go
into parted again to delete the partition and recreate it. Again it
works until I reboot wether or not I have it set to mount in the fstab
or to mount by hand later.

Basically this is what I am doing to create the partitions:

#parted /dev/sdb
#mkpart primary xfs 0.0 2622488.000
#print
Disk geometry for /dev/sdc: 0.000-2622488.000 megabytes
Disk label type: msdos
Minor Start End Type Filesystem Flags
1 0.031 525333.742 primary xfs type=83
#quit

then after the partition was created I did

# mkfs.xfs -f /dev/sdc1
meta-data=/dev/sdc1 isize=256 agcount=32,
agsize=20979885 blks
= sectsz=512
data = bsize=4096 blocks=671356320,
imaxpct=25
= sunit=0 swidth=0 blks,
unwritten=1
naming =version 2 bsize=4096
log =internal log bsize=4096 blocks=32768,
version=1
= sectsz=512 sunit=0 blks
realtime =none extsz=65536 blocks=0, rtextents=0

#mount /dev/sdc1 /scr3
#df -h
/dev/sdc1 2.6T 528K 2.6T 1% /scr3

I can mount and unmount this device repeatedly with no problems until
I reboot.

Thanks for the help.

Here is a small update.

I am pretty sure I am using parted correctly. I tried doing one
partition as ext3 and one as reiserfs just in case the problem was
with a bug in xfs. The ext3 partition works perfectly but the
reiserfs partition has the exact same problem of the partition table
being lost on reboot.

I'd rather not use ext3 because I've read that there are a lot of
performance problems in raid systems, but if I can't get the others to
work I may have to.
