Hi loic, Back on this issue... Using the epel package, I still get " prepared-only " disks, e.g : /dev/sdc : /dev/sdc1 ceph data, prepared, cluster ceph, journal /dev/sdc2 /dev/sdc2 ceph journal, for /dev/sdc1 Looking at udev output, I can see that there is no "ACTION=add" with ID_PART_ENTRY_TYPE= 4fbd7e29-9d25-41b8-afd0-062c0ceff05d , only a "change" action. This was on a previously prepared disk, which I zapped. When I start "partx -u /dev/sdc" , then and only then the kernel sees the new partitions, and it also sees the old ones disappeared too - see the part udev log attached. In this log are only the events that udev saw right when I ran 'partx -u' : nothing before, and nothing after. This still looks like it's not "partx -a" that should be used on this system when running ceph-disk prepare, but "partx -u".. ? And off course, after the "partx -u" is run, the disk is activated. This is what I have : [root@ceph1 ~]# rpm -qf /usr/sbin/partx util-linux-2.23.2-16.el7.x86_64 [root@ceph1 ~]# cat /etc/redhat-release CentOS Linux release 7.0.1406 (Core) [root@ceph1 ~]# rpm -qi ceph Name : ceph Epoch : 1 Version : 0.80.5 Release : 8.el7 Architecture: x86_64 Install Date: Tue 28 Oct 2014 12:28:41 PM CET Group : System Environment/Base Size : 39154515 License : GPL-2.0 Signature : RSA/SHA256, Sat 23 Aug 2014 08:02:08 PM CEST, Key ID 6a2faea2352c64e5 Source RPM : ceph-0.80.5-8.el7.src.rpm Build Date : Fri 22 Aug 2014 02:36:05 AM CEST Build Host : buildhw-08.phx2.fedoraproject.org Regards _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
