[ceph-users] waiting for 1 open ops to drain

I am using ceph 0.58 and kernel 3.9-rc2 and btrfs on my osds. I have an osd that starts up but blocks with the log message 'waiting for 1 open ops to drain'. This never happens, and I can't get the osd 'up'. I need to clear this problem. I have recently had an osd go problematic and I have recre

Hi there! What steps needs to be perform if we have totally lost a node. As I already understand from docs, OSDs must be recreated (disabled, removed and again created, right?) But what about MON and MDS? -- Igor Laskovy facebook.com/igor.laskovy Kiev, Ukraine ___

Dan, Sebastién, thanks for the hints. For Inktank: There's no doubt that setting the appropriate pg_num is a very important parameter to set, and due to the lack of a stable command to increase them, the workaround by Sébastien Han along with the advises by Dan van der Ster should be included in t

Igor, I am sure that I'm right in saying that you just have to create a new filesystem (btrfs?) on the new block device, mount it, and then initialise the osd with: ceph-osd -i --mkfs Then you can start the osd with: ceph-osd -i Since you are replacing an osd that already existed, the cluste

[ceph-users] pgs stuck unclean

Hello! I've deployed a test ceph cluster according to this guide: http://ceph.com/docs/master/start/quick-start/ The problem is that the cluster will never go to a clean state by itself. The corresponding outputs are the following: root@test-4:~# ceph health HEALTH_WARN 3 pgs degraded; 38 pgs

The MDS doesn't have any local state. You just need start up the daemon somewhere with a name and key that are known to the cluster (these can be different from or the same as the one that existed on the dead node; doesn't matter!). -Greg Software Engineer #42 @ http://inktank.com | http://cep

Yeah. If you run "ceph auth list" you'll get a dump of all the users and keys the cluster knows about; each of your daemons has that key stored somewhere locally (generally in /var/lib/ceph/ceph-[osd|mds|mon].$id). You can create more or copy an unused MDS one. I believe the docs include informa
