This should work, I test that frequently. Are the /dev/dm-xx mounted/accessed by anything else? (And, because of a bug, I'm hoping you're running SLES9 SP1 with a kernel updated to post-SP1, because that one was broken with DM/md stacking due to an oversight... But then, you'd have seen an oops already ;-) SP2 will bring much improved DM multipath, too. Actually, in the future you may want to annoy the Novell / SUSE support organization with questions about SLES9 kernels, because they are fairl= y different from mainline ;-) Sincerely, Lars Marowsky-Br=E9e --=20 High Availability & Clustering SUSE Labs, Research and Development SUSE LINUX Products GmbH - A Novell Business -- Charles Darwin "Ignorance more frequently begets confidence than does knowledge" - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
