In this case I can figure out what the message is, but really, we're all pattern matching animals and the specific strings in /usr/include/asm-generic/errno.h are what we know. > no space left on device, but: > > 2012-09-04 18:46:38.242840 mon.0 [INF] pgmap v2883: 576 pgs: 512 acti= ve+clean, > 64 active+recovering; 1250 MB data, 14391 MB used, 844 MB / 15236 MB = avail; > 36677/215076 degraded (17.053%) > > there is space left? Only 844 MB available, with the pseudo-random placement policies, means you practically are out of space. It looks like you had only 15GB to begin with, and with typical replication, that's <5GB usable space. That is dangerously small for any real use; Ceph currently does not cope very well with running out of space. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
