Tried to take snapshot on an already existing up+replaying image from Slave Node. for i in {1..25}; do rbd snap create test/liver1@snappy$i --cluster slave; done Actual results: Snapshot is getting created on the Slave Node. rbd -p test --image liver1 snap ls --cluster slave 120 snappy1 11111 MB Expected results: Snapshot should never get created on Slave Node. Additional info: This happened to me twice, mostly the 1st iteration is going through.
