I'm benchmarking this, using some 50 'dd if=file[1..50] of=/dev/null' to simuate my application. This will work for a few seconds, giving me pretty good i/o speed, but then all the processes go defunct and stay like that some minutes (i really don't know how long). I tried to do the bechmark with the individual drives, and no problem there... Anyone have a clue? Configuration: - Promise 133 TX2 (20269 manually patched in. Just made som defines to alias it to the 20268) - 2 WD1200BB drives (hde and hdg) /etc/raidtab: raiddev /dev/md0 raid-level 0 nr-raid-disks 2 persistent-superblock 0 chunk-size 4096 device /dev/hde raid-disk 0 device /dev/hdg raid-disk 1 -- Roy Sigurd Karlsbakk, MCSE, MCNE, CLS, LCA Computers are like air conditioners.
