Hi I think I hit the same issue with the journal partitions when upgrading our cluster to Jewel and Ubuntu 16.04.
Our solutions to this issue was the change the GUID partition ID/type of the CEPH journal partition to the official one by hand. Afterwards udev changes the raw journal partitions the correct owner/groups at boot. The GUID for a CEPH journal partition should be "45B0969E-9B03-4F30-B4C6-B4B80CEFF106" I haven't been able to find this info in the documentation on the ceph site but there are some info on wikipedia https://en.wikipedia.org/wiki/GUID_Partition_Table I hope this helps you enough to resolve you issue :) Kind regards Brian Lagoni DevOps System administrator, Engineering Tools Unity Technologies On 10 June 2016 at 04:20, 한승진 <yongi...@gmail.com> wrote: > Hi Cephers, > > I hava a ceph cluster Jewel on Ubuntu 16.04. > > What I am wondering is Whenever I reboot the OSD nodes, the OSD init > service is failed. > > The reason why is that the owner not changed in journal partition. > > I have btrfs file system and the devices are sdc1,sdd1,sde1.. and so on. > They are also linked with journal device which are sdb1,sdb2,sdb3..and so > on. > > btrfs devices are all belong to ceph:ceph when OSDs are activating. > > root@cephnode01:~# ll /dev/sdc1 /dev/sdd1 /dev/sde1 > brw-rw---- 1 ceph ceph 8, 33 Jun 10 10:48 /dev/sdc1 > brw-rw---- 1 ceph ceph 8, 49 Jun 10 10:44 /dev/sdd1 > brw-rw---- 1 ceph ceph 8, 65 Jun 10 10:44 /dev/sde1 > > However, journal devices are not belong to ceph user and group. > > brw-rw---- 1 root disk 8, 17 Jun 10 11:02 /dev/sdb1 > brw-rw---- 1 root disk 8, 18 Jun 10 11:00 /dev/sdb2 > brw-rw---- 1 root disk 8, 19 Jun 10 10:57 /dev/sdb3 > > Is it a bug of ceph? > > > Thank you > > > > _______________________________________________ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > >
