Hi All,
And further to my last email, does anyone have any experience of using ceph-deploy with storage configured via multipath, please?
Currently, we deploy new OSDs with:
ceph-deploy disk zap ceph-sn1.example.com:sdb
ceph-deploy --overwrite-conf config pull ceph-sn1.example.comceph-deploy osd prepare ceph-sn1.example.com:sdb
I note that these are not the full path to the device node on the storage host, e.g.:
ceph-deploy disk zap ceph-sn1.example.com:/dev/sdb
Does ceph-deploy accept the full path, and if so, should providing a path via the device mapper also work? e.g.:
ceph-deploy disk zap ceph-sn1.example.com:/dev/
mapper/disk1
The above usage is correct, you *could* hit this issue http://tracker.ceph.com/issues/19489 and there is a fix for that here https://github.com/ceph/ceph/pull/16123
