So I'd like now to reduce the size of the snapshot for being able to create a second one. man lvreduce says: Shrinking snapshot logical volumes (...) is supported as well. Ok, that's fine. But normally, before shrinking a lv, the file system has to be reduced. But does the snapshot have a fs ? I never ran a mkfs.xxxx on it. Can I just reduce the size without doing anything before ? Or do I have to provide a -r to lvreduce ? > > Thanks for any information. The (non-thinly-provisioned) snapshot fills up from beginning to end. If it says it is 50% full, you should be able to reduce its size by roughly half. Be sure to leave a good margin of space for snapshots to use, as they will become invalid if they are overfilled. brassow _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
