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.
