Re: [ceph-users] mkfs.ext4 hang on RBD volume

Can you ensure that you have the "admin socket" configured for your librbd-backed VM so that you can do the following when you hit that condition: ceph --admin-daemon objecter_requests That will dump out any hung IO requests between librbd and the OSDs. I would also check your librbd logs to

Re: [ceph-users] mkfs.ext4 hang on RBD volume

We are using librbd on a host with CentOS 7.2 via virtio-blk. This server hosts the VMs on which we are doing our tests. But we have exactly the same behaviour than #9071. We try to follow the thread to the bug 8818 but we didn't reproduce the issue with a lot of DD. Each time we try with

Are you using krbd directly within the VM or librbd via virtio-blk/scsi? Ticket #9071 is against krbd. On Mon, Jan 16, 2017 at 11:34 AM, Vincent Godin wrote: > In fact, we can reproduce the problem from VM with CentOS 6.7, 7.2 or 7.3. > We can reproduce it each time with

In fact, we can reproduce the problem from VM with CentOS 6.7, 7.2 or 7.3. We can reproduce it each time with this config : one VM (here in CentOS 6.7) with 16 RBD volumes of 100GB attached. When we launch in serial mkfs.ext4 on each of these volumes, we allways encounter the problem on one of

FYI, our ipv6 is lagging a bit behind ipv4 (and the red hat nameservers may take a bit to catch up), so you may see the old site for just a little bit longer. On Mon, Jan 16, 2017 at 10:03 AM, Patrick McGarry wrote: > Ok, the new website should be up and functional. Shout
