Hi,
I have a fibre channel attached JBOD storage system that contains
multiple FC connected disk drives that I am trying to use with 3 OSD
servers, running on older HP hardware as a test system for ceph. I am
finding that ceph-deploy and ceph-disk seems to have issues with non
/dev/sdX devices. Issues include:
1. I had to modify ceph-disk to not exit when it saw the root device
/dev/cciss/c0d0.
2. I could not get multipath devices to work with ceph-deploy or
ceph-disk, but they only seem to work with /dev/sdX devices. These
tools do not seem to like device names like: /dev/disk/by-id/
dm-uuid-mpath-3600a0b800019b33600001a0251dfba6e
3. As all 3 of my systems sees all the FC disks, they all try to mount
all the OSD disks, which corrupts the local XFS file systems. Is there
a black/white list available to say which disks can be mounted on which
server. As my system is just a simple jbod, I cannot mask LUNs.
Thanks!
Eric
