It works fine on two channels, but when I configure the system to use the second controller it will not find the disks on the second controller. My working configuration is: /dev/hde /dev/hdf /dev/hdg /dev/hdh My non-working config is: /dev/hde /dev/hdg /dev/hdi /dev/hdk Where hde-hdh are on my PCI promise controller, and hdi-hdl are on my onboard HighPoint 366 controller. (The same array worked on just the Highpoint 366 controller as well) System info Linux-2.6.8.1 non-SMP. The following is my /etc/raidtab (which is set up for the non-working config, but works with the working config...) raiddev /dev/md0 raid-level 5 nr-raid-disks 4 persistent-superblock 1 parity-algorithm left-symmetric chunk-size 128 device /dev/hde raid-disk 0 device /dev/hdg raid-disk 1 device /dev/hdi raid-disk 2 device /dev/hdk raid-disk 3 Any ideas? Thanks, Nate
