Not sure if this is XFS related or softare RAID0 or what, 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, 220.127.116.11-64.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

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:
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.
