How do you know you have a deadlock in ImageWatcher? I don't see that in the provided log. Can you provide a backtrace for all threads? On Sun, Feb 26, 2017 at 7:44 PM, Rajesh Kumar wrote: > Hi, > > We are using Ceph Jewel 10.2.5 stable release. We see deadlock with image >

[ceph-users] VM hang on ceph

2017-02-26 Thread Rajesh Kumar

Hi, We are using Ceph Jewel 10.2.5 stable release. We see deadlock with image watcher and VM becomes dead, at this point I can't ping the VM. Here are last few lines from qemu-rbd log. Has anyone seen this and is there a fix for it? 2017-02-26 11:05:54.647071 7faa927fc700 11 objectcacher
