Re: [ceph-users] CoreOS Cluster of 7 machines and Ceph

Sorry for the late reply - been traveling. I'm doing exactly that right now, using the ceph-docker container. It's just in my test rack for now, but hardware arrived this week to seed the production version. I'm using separate containers for each daemon, including a container for each OSD. I've

Re: [ceph-users] Crashing OSDs (suicide timeout, following a single pool)

With regards to this export/import process, I've been exporting a pg from an osd for more than 24 hours now. The entire OSD only has 8.6GB of data. 3GB of that is in omap. The export for this particular PG is only 108MB in size right now, after more than 24 hours. How is it possible that a

Re: [ceph-users] Crashing OSDs (suicide timeout, following a single pool)

Nice catch. That was a copy-paste error. Sorry it should have read: 3. Flush the journal and export the primary version of the PG. This took 1 minute on a well-behaved PG and 4 hours on the misbehaving PG i.e. ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-16 --journal-path

Re: [ceph-users] what does the 'rbd watch ' mean?

That command is used for debugging to show the notifications sent by librbd whenever image properties change. These notifications are used by other librbd clients with the same image open to synchronize state (e.g. a snapshot was created so instruct the other librbd client to refresh the image's

[ceph-users] Required maintenance for upgraded CephFS filesystems

Hi, If you do not have a CephFS filesystem that was created with a Ceph version older than Firefly, then you can ignore this message. If you have such a filesystem, you need to run a special command at some point while you are using Jewel, but before upgrading to future versions. Please see the

Re: [ceph-users] CephFS: slow writes over NFS when fs is mounted with kernel driver but fast with Fuse

It should be noted that using "async" with NFS _will_ corrupt your data if anything happens. It's ok-ish for something like an image library, but it's most certainly not OK for VM drives, databases, or if you write any kind of binary blobs that you can't recreate. If ceph-fuse is fast (you
