Is this XFS problem or something else? : xfs_trans_read_buf error 5 buf count 4096

["Bond Masuda" <bm007@cox.net>]

Not sure if this is XFS related or not, but this seems to be reoccurring. 

The hardware is:

Dell Inspiron 530, Q6600 quad core, 4GB Ram, 2x750GB SATA HDD

I have Fedora 8/64bit installed, using XFS for "/", ext3 for "/boot". The
two identical 750GB drives are striped to create a 1.4TB "md1" device, which
is mounted as "/". Kernel is from Fedora8, 2.6.24.4-64.fc8.

During the install, everything seemed to work fine. I was able to use the
system without any problems for about 2 days. Then I reboot, and the md1
device running XFS shows the following error messages:

I/O error in filesystem ("md1") meta-data dev md1 block 0x15d048574120008
("xfs_trans_read_buf") error 5 buf count 4096
attempt to access beyond end of device
md1: rw=0, want=98239738096517136, limit=2927780864

The above message repeats several times, but the system manages to boot to
runlevel 3. I can login, but almost any command triggers that message which
has flooded the logs. here is xfs_info on "/":

meta-data=/dev/root			isize=256	agcount=32,
agsize=11436608 blks
	   =					sectsz=512	attr=1

blks, lazy-count=0

At first, I thought perhaps something wrong with the disks so I had them
replaced. Reinstalled Fedora8 as before, then again, 2 days later (I don't
know if the 2 day time period is coincidental or not), I reboot, and the
exact same problem occurred. Since I've gone through 4 brand new 750GB HDD
now, (Seagate diagnostics show all the disks to be fine in both occurances,
but I replaced them anyway) I'm feeling that this is not a hardware issue,
but software related.

A search on google seems to show others with possibly similar issues:

http://ubuntuforums.org/archive/index.php/t-568309.html

Is that related? Other google searches show a pattern of this problem only
with >1TB XFS partitions, but that's just what I found googling.

I'm considering re-installing again, but using ext3 for "/" to see if the
problem reoccurs, in hopes of "isolating" the issue. Not sure if it is
related to XFS, the software stripe md1, or something else (but I don't
think it's HDD related now).

Thanks for any info or assistance. Though the system isn't really usable,
(many commands fail, but does boot to runlevel 3 and permits me to login)
I'll leave it as is for today so let me know if there's other info I can try
to gather that would be useful.

Any help would be appreciated.
