Hello, I'm quite new to ceph, so please forgive my ignorance. Yesterday, I've deployed small test cluster (3 nodes, 2 SATA + 1 SSD OSD / node) I enabled MDS server and created cephfs data + metadata pools and created filesystem. However upon mount requests, I'm getting following error: [Apr20 10:09] libceph: mon0 10.0.0.1:6789 feature set mismatch, my 2b84a042aca < server's 102b84a042aca, missing 1000000000000 This two threads seem related to me: http://www.spinics.net/lists/ceph-users/msg17406.html ("protocol feature mismatch" after upgrading to Hammer) and http://www.spinics.net/lists/ceph-users/msg17445.html (crush issues in v0.94 hammer) but I'm using 0.94.1 on all nodes (and 3.18.11) kernel and am still getting those errors, which to my understanding I shouldn't be.. What should I check please? In case it could help, my crushmap can be checked here: http://nik.lbox.cz/download/ceph/crushmap.txt with best regards nik -- ------------------------------------- Ing.
