Hej, I am using Suse 9.1 and have build (finally) my Raid-5 volume using the raidtools. When I write large amounts of data to the array (i.e. 50 GB) in a cp or mv operation, it always stops in the middle of the copy. It waits. There are no kernel messages, no errors, it just waits. The strange part is that after I do a "more /proc/mdstat" my cp/mv operation continues. Performance is descent with approx. 20-30MB/s writes and 80MB/s reads. You can see the rest of my setup in a previous post: http://marc.theaimsgroup.com/?l=linux-raid&m=108738559332187&w=2 Has anybody seen this before? Alwin P.S. I am using two Maxtor 200GB IDE disks and two identical disks but with SATA interface. My box is a Dell 400SC and I run Suse 9.1 with the default kernel. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
