Hi I made first release of my snapshot storage that can hold unlimited number of snapshots and share data between them: http://people.redhat.com/mpatocka/patches/kernel/new-snapshots/ How-to-use is at the beginning of dm-multisnapshot.patch If you see some errors, report them. This storage uses btree with the key (chunk number, snapshot range). It uses log-structured storage, so that it is safe w.r.t. crash. TODO: - reclaim allocated space, allow deleting snapshots - writable snapshots Mikulas -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
