Neil, Thanks for the reply. Software Raid is linked directly into the kernel and not a module. I notice using make menuconfig on 2.4.21 there is no specific autodetect option as with earlier kernels, and presume this is no longer necessary. All options under Multi-Device support are linked in, as is Reiserfs which I am using on the array. dmesg shows that autodetection is taking place but it does not appear to find anything. raidstart --all seems to bring it up, as do the initscripts if I reconfigure raidtools2. Any suggestions welcome. regards, Darryl -- _________________________________________________________ - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
