It's a little unclear what you're asking… but if I understand you correctly, you've read somewhere that `rbd lock` is to be depreciated? Where abouts did you read this? The documentation still shows it being available, and does not discuss depreciation or replacement of the feature: http://docs.ceph.com/docs/master/man/8/rbd/#commands I ask because I'm looking to try and set up a couple of my VMs as HA VMs that can migrate between my two VM hosts, and for this purpose, having the ability to detect when the other node is "up" would be really handy to prevent data corruption. I'm not sure what happens to the lock when the client that requested it dies either… Ideally it should die with the client, but something tells me it hangs around. Again, the documentation does not say. Could someone clarify the status of this? -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.
