Hi, I wanted to modify several RAID1 partitions (changing the preferred minor), which requires to mdadm --stop /dev/md? before. This worked well except with the RAID device which contained an LVM physical volume. I could not stop that contains an pv, even after vgchange -a n and vgexport. The RAID device is still busy. How could I make LVM to release the underlying device (without destroying the contents)? regards Hadmut -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
