I could not report a bug in bug tracer (I am not allowed to or I just couldn't find appropriate button?) so I send it here. There is a problem on debian squeeze with kernel 2.6.32 and ceph kernel module. Ceph version 0.24.1-1~bpo60+1. I can not mount filesystem on client machine: client: # mount -t ceph 10.1.0.15:/ /ceph # mount: 10.1.0.15:/: can't read superblock mon0 log: 2011-01-18 12:08:23.534637 7ff675d6d710 -- 10.1.0.15:6789/0 >> 10.1.0.29:0/1783749524 pipe(0xd5b000 sd=8 pgs=0 cs=0 l=0).accept peer addr is really 10.1.0.29:0/1783749524 (socket is 10.1.0.29:48987/0) 2011-01-18 12:10:27.338512 7ff675d6d710 -- 10.1.0.15:6789/0 >> 10.1.0.29:0/4142445380 pipe(0xd5d260 sd=8 pgs=0 cs=0 l=0).accept peer addr is really 10.1.0.29:0/4142445380 (socket is 10.1.0.29:44569/0) mon console: # ceph -s 2011-01-18 12:50:54.083205 pg v287: 528 pgs: 528 active+clean; 0 KB data, 27640 KB used, 2021 MB / 2048 MB avail 2011-01-18 12:50:54.084113 mds e6: 1/1/1 up {0=up:creating}, 1 up:standby 2011-01-18 12:50:54.084188 osd e9: 2 osds: 2 up, 2 in 2011-01-18 12:50:54.084286 log 2011-01-18 12:46:59.375405 osd0 10.1.0.15:6801/14921 285 : [INF] 3.1p0 scrub ok 2011-01-18 12:50:54.084432 mon e1: 2 mons at {0=10.1.0.15:6789/0,1=10.1.0.27:6789/0} -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
