On the same 3 SCSI disks, I can create a RAID0 set, and run repeated bonnies on it. On these disks, if I then make a RAID5 set, it starts making the /dev/md0, and then dies, flooding my console with scsi bus reset error messages. The higher the chunksize I use, the later this happens, but I can't get RAID5 to work. It's a dual celeron 550 box, 2.2.13 patched, AHA2940, and 3 SCSI2 (but 5 MB/sec) 420 MB Seagate disks. Something about SCSI bus activity, either breaking the drives or the card driver? Any ideas? I have some interesting bonnie runs, if people care. -- Edward Schernau http://www.schernau.com Network Architect mailto:[EMAIL PROTECTED] Rational Computing Providence, RI, USA, Earth
