All, I am using Fedora core 1 as os and on board Fasttrak PDC20267 as RAID controller. It works fine with upto 80GB disks(I am using RAID1), but when I try to make an array with two 160GB disks the pdcraid module is not being loaded. The array is being created from RAID BIOS level (using ctrl+F). Here is some output- [root@~ root]# insmod pdcraid Using /lib/modules/2.4.22-1.2115.nptlsmp/kernel/drivers/ide/raid/pdcraid.o /lib/modules/2.4.22-1.2115.nptlsmp/kernel/drivers/ide/raid/pdcraid.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg [root@~ root]# dmesg | less Promise Fasttrak(tm) Softwareraid driver 0.03beta: No raid array found Any clue? Thanks in advance -Nabendu
