Hi Im trying to mount a ceph rdb on a ubuntu 12.04 LTS with kernel 3.8.0 While our ceph cluster is healty running on
0.67.4 I’m not able to map the rbd device The command: rbd map archiveadmin --pool rbd --name client.admin --log-to-stderr rbd: add failed: (5) Input/output error In syslog: Oct 30 10:48:13 ceph00 kernel: [ 135.945476] Key type ceph registered Oct 30 10:48:13 ceph00 kernel: [ 135.945483] libceph: loaded (mon/osd proto 15/24, osdmap 5/6 5/6) Oct 30 10:48:13 ceph00 kernel: [ 135.954829] rbd: loaded rbd (rados block device) Oct 30 10:48:13 ceph00 kernel: [ 135.956200] libceph: mon0 10.100.214.11:6789 feature set mismatch, my 40002 < server's 40040002, missing 40000000 Oct 30 10:48:13 ceph00 kernel: [ 135.956400] libceph: mon0 10.100.214.11:6789 socket error on read Where does this mismatch come from? I thought I have upgrade all ceph packets everywhere to 0.67.4, or is the kernel too old? Regards Andi |
