Not perfectly sure what you mean with latest maintenance release. However, I just synched again the SLES 11 updates from: https://nu.novell.com/repo/\$RCE/SLES11-Updates/sle-11-x86_64/ however, no new multipath-tools or kernel update is available. Do you know which version is supposed to work? regards Sebastian -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
