This is because partition typecode GUID is just not supported on MBR partition. If your journals live on an MBR disk you'll have to add some custom udev rules yourself. This is what I did: [root@ceph-10-206-123-182 ~]# cat /etc/udev/rules.d/70-persisnent-ceph-journal.rules KERNEL=="sdc5", SUBSYSTEM=="block", ATTRS{model}=="KINGSTON SV300S3", OWNER="ceph", GROUP="ceph" KERNEL=="sdc6", SUBSYSTEM=="block", ATTRS{model}=="KINGSTON SV300S3", OWNER="ceph", GROUP="ceph" Cheers, -K. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
