I've just tried your "dd" command on a couple of boxen.  Both succeeded.



The systems were
1:
Disk: IDE
System Ram: 256MB
CPU: (1) Pentium III (copermine) 1GHz
Kernel: Linux version 2.4.23-rc4-xfs
XFS: SGI-XFS CVS-2003-11-24_06:00_UTC with ACLs, realtime, no debug enabled

2:
Disk: Hardware raid-5, "Adaptec Raid Controller 1.1-3"
System Ram: 2GB
CPU: (2) Intel(R) Xeon(TM) CPU 2.80GHz -- acting as 4 processors
Kernel: Linux version 2.4.23-rc4-xfs
XFS: SGI-XFS CVS-2003-11-24_06:00_UTC with ACLs, realtime, no debug enabled

Hello,

that was a discusion about 3ware driver. It has resulted in XFS bug most
probably.

With kernel 2.4.22 or 2.4.23 (SGI XFS snapshot-2.4.23-2003-12-01_00:33_UTC with
no debug enabled)
dd if=/dev/zero of=/file_on_xfs_partition bs=448k count=23405

lockup whole server. xfs partition on SCSI disc. It happen when file becomes
about 5GB of size.

First I've discovered it with iozone benchmark and 10GB file..

2.4.20 kernel with IDE disc seems to be OK as well as 2.6.0 kernel on the same
configuration as 2.4.23 kernel was.

Generally not with such a small rev difference. You could try the latest driver, and firmware in the 7.7. The driver source is on the Red Hat drivers disk. You should be able to drop in the .c, and .h in drivers/scsi, and recompile.

PS- Personally I'd suspect an XFS bug. Try reiserfs. I've been running 2.4.23pres, and 2.4.23 on hundreds of 3ware of numerous different types. With no issue with the prior firmware release.
There are a lot of people, running RAID5 3ware's w/ Terrabyte arrays.  I
don't want to say it is not an XFS bug, but I find that highly suspect.
Well, with ext3 parition iozone program finishes OK. So it looks like some XFS
bug.
FWIW have you sent this on to the XFS list?

thanks,
 Joshua
