Hi all, I'm new to Luminous, when I use ceph-volume create to add a new filestore OSD, it will tell me that the journal's header magic is not good. But the journal device is a new LV. How to make it write the new OSD's header to the journal? And it seems this error message will not affect the creation and start of the OSD, but it complains the bad header magic in the log every time it boots. journal _open /var/lib/ceph/osd/ceph-1/journal fd 30: 21474836480 bytes, block size 4096 bytes, directio = 1, aio = 1 journal do_read_entry(3922624512): bad header magic journal do_read_entry(3922624512): bad header magic journal _open /var/lib/ceph/osd/ceph-1/journal fd 30: 21474836480 bytes, block size 4096 bytes, directio = 1, aio = 1 Should I care about this? Is the OSD using the journal with bad magic header normally? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
