Hi,
I have a new empty cluster, v0.56.3 - Ubuntu 12.04 with kernel 3.4.36
I have just run mkcephfs and inject the crushmap
(http://pastebin.com/F1nYKZZR)
I have modified the rulesets, sice I want to distribute the data on a
per-room basis
This is the osd tree: http://pastebin.com/JsEsWjTx
I have another machine to mount the Cephfs and re-export it via Samba.
If I run the command "ceph osd crush tunables optimal" or "ceph osd
crush tunables bobtail" on my cluster, the mount fails with "mount error
5 = Input/output error" and in syslog I have
libceph: mon0 192.168.21.11:6789 feature set mismatch, my 8a < server's
204008a, missing 2040000
libceph: mon0 192.168.21.11:6789 socket error on read
Otherwise, if I run "ceph osd crush tunables default" the mount success.
Is advisable to run "ceph osd crush tunables bobtail" on a Bobtail cluster?
Thanks
