So, I have been using the lvm mirror target on CentOS 5.1 (2.6.18-53.1.21.el5xen) for some time now; it works great for most things, and gives me much more flexibility than putting my PVs on md devices. The other day I tried to create a snapshot: lvcreate -s -L 100M -d hydra_domU/test -n test_snap it returned: Snapshots and mirrors may not yet be mixed. is the mirror target still under active development? or is it a problem with my setup? thanks. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
