What I mean by my question is "I didn't see block.db or sdaa1 mentioned in the log. Maybe that is the problem." > > Now, re-reading the thread, you say that it sometimes does boot > normally? On this host right now we are unable to start the 6 OSDs with block.db on sdaa[1-6]. On another two hosts earlier today, we had this same problem, but after rebooting a couple times the OSDs started normally. We've rebooted this host with osd.48 and others a few times now but no such luck. > ceph-volume tries (in different ways) to ensure that the > devices > used are the correct ones.

If osd.48 comes up online, how does the > /var/lib/osd/ceph-48 looks? the same? As far as we can tell that partuuid is only applied to sdaa1: # blkid | grep 3381a121-1c1b-4e45-a986-c1871c363edc /dev/sdaa1: PARTLABEL="primary" PARTUUID="3381a121-1c1b-4e45-a986-c1871c363edc" We don't manage to bring osd.48 online, but comparing it to another osd that *is* up... nothing stands out as different. In case it helps, here's how we created these osds (nothing unusual...): dd if=/dev/zero of=/dev/sdaa bs=512 count=1 parted -s /dev/sdaa mklabel gpt parted -s -a optimal /dev/sdaa mkpart primary "0%" "16%" ceph-volume lvm create --bluestore --data /dev/sda --block.db /dev/sdaa1 Thanks for all your help! dan > > > > > > Here's the osd dir: > > > > # ls -l /var/lib/ceph/osd/ceph-48/ > > total 24 > > lrwxrwxrwx. 1 ceph ceph 93 Jun 7 16:46 block -> > > /dev/ceph-34f24306-d90c-49ff-bafb-2657a6a18010/osd-block-99fd8e36-fc4d-4bbc-83d9-f5e611cde4b5 > > lrwxrwxrwx. 1 root root 10 Jun 7 16:46 block.db -> /dev/sdaa1 > > -rw-------. 1 ceph ceph 37 Jun 7 16:46 ceph_fsid > > -rw-------. 1 ceph ceph 37 Jun 7 16:46 fsid > > -rw-------. 1 ceph ceph 56 Jun 7 16:46 keyring > > -rw-------. 1 ceph ceph 6 Jun 7 16:46 ready > > -rw-------. 1 ceph ceph 10 Jun 7 16:46 type > > -rw-------. 1 ceph ceph 3 Jun 7 16:46 whoami > > > > # ls -l > > /dev/ceph-34f24306-d90c-49ff-bafb-2657a6a18010/osd-block-99fd8e36-fc4d-4bbc-83d9-f5e611cde4b5 > > lrwxrwxrwx. 1 root root 7 Jun 7 16:46 > > /dev/ceph-34f24306-d90c-49ff-bafb-2657a6a18010/osd-block-99fd8e36-fc4d-4bbc-83d9-f5e611cde4b5 > > -> ../dm-4 > > > > # ls -l /dev/dm-4 > > brw-rw----. 1 ceph ceph 253, 4 Jun 7 16:46 /dev/dm-4 > > > > > > --- Logical volume --- > > LV Path > > /dev/ceph-34f24306-d90c-49ff-bafb-2657a6a18010/osd-block-99fd8e36-fc4d-4bbc-83d9-f5e611cde4b5 > > LV Name osd-block-99fd8e36-fc4d-4bbc-83d9-f5e611cde4b5 > > VG Name ceph-34f24306-d90c-49ff-bafb-2657a6a18010 > > LV UUID FQkRxS-No7X-ajkP-5L3N-K22a-IXg6-QLceZC > > LV Write Access read/write > > LV Creation host, time p06253939y61826.cern.ch, 2018-03-15 10:57:37 +0100 > > LV Status available > > # open 0 > > LV Size <5.46 TiB > > Current LE 1430791 > > Segments 1 > > Allocation inherit > > Read ahead sectors auto > > -
