I’m at step 6. I updated/rebooted the host to complete “installing the new packages and restarting the ceph-osd daemon” on the first OSD host. All the systemctl definitions to start the OSDs were deleted, all the properties in /var/lib/ceph/osd/ceph-* directories were deleted. All the files in /var/lib/ceph/osd-lockbox, for comparison, were untouched and still present.
Peeking into step 7 I can run ceph-volume: # ceph-volume simple scan /dev/sda1 Running command: /usr/sbin/cryptsetup status /dev/sda1 Running command: /usr/sbin/cryptsetup status 93fb5f2f-0273-4c87-a718-886d7e6db983 Running command: /bin/mount -v /dev/sda5 /tmp/tmpF5F8t2 stdout: mount: /dev/sda5 mounted on /tmp/tmpF5F8t2.

If you are at Step 6 then it is *crucial* to understand that the tooling used to create the OSDs is no longer available and Step 7 *is absolutely required*. ceph-volume has to scan the system and give you the output of all OSDs found so that it can persist them in /etc/ceph/osd/*.json files and then can later be "activated". I didn't do anything to specific commands for just updating the ceph RPMs in this process. It is not clear if you are at Step 6 and wondering why OSDs are not up, or you are past that and ceph-volume wasn't able to detect anything. peter Peter Eisch Senior Site Reliability Engineer T 1.612.659.3228<tel:1.612.659.3228> [Facebook]<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.facebook.com%2FVirginPulse&data=02%7C01%7Cpeter.eisch%40virginpulse.com%7Ccb996f99f71d41410beb08d7106bece7%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636995928035433302&sdata=S3yV1H%2BF0hz5uqB0Ac4sdyEBKIttg18YqtRykeyf1oU%3D&reserved=0> [LinkedIn]<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fvirgin-pulse&data=02%7C01%7Cpeter.eisch%40virginpulse.com%7Ccb996f99f71d41410beb08d7106bece7%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636995928035433302&sdata=6GM0bMxnX1NAOj%2BIuSl0PvzP5zfEaD1ovEQmmphPpzc%3D&reserved=0> [Twitter]<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftwitter.com%2Fvirginpulse&data=02%7C01%7Cpeter.eisch%40virginpulse.com%7Ccb996f99f71d41410beb08d7106bece7%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636995928035443297&sdata=K%2FOGzFbm5318%2FXVPAllf2Rd%2Fvv7QkfW2W9wDuk%2FwsRU%3D&reserved=0> virginpulse.com<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.virginpulse.com%2F&data=02%7C01%7Cpeter.eisch%40virginpulse.com%7Ccb996f99f71d41410beb08d7106bece7%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636995928035443297&sdata=uSbgrsQuxX8JZg1%2BLc9vKvsoCKOwE1mQ4QEi6TqpBV8%3D&reserved=0> | virginpulse.com/global-challenge<https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.virginpulse.com%2Fen-gb%2Fglobal-challenge%2F&data=02%7C01%7Cpeter.eisch%40virginpulse.com%7Ccb996f99f71d41410beb08d7106bece7%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636995928035453291&sdata=in0gDTqunNVnWtV9CobiUJ4QGyIFgfehJl5%2B970soPs%3D&reserved=0> Australia | Bosnia and Herzegovina | Brazil | Canada | Singapore | Switzerland | United Kingdom | USA Confidentiality Notice: The information contained in this e-mail, including any attachment(s), is intended solely for use by the designated recipient(s).

Ceph used to use udev to detect the OSDs and then moved to lvm, which kind of OSDs are you running? Blustore or filestore? Which version did you use to create them? Cheers! El 24 jul 2019, a les 20:04, Peter Eisch <mailto:mailto<mailto:mailto>:peter.ei...@virginpulse.com<mailto:peter.ei...@virginpulse.com>> va escriure: Hi, I’m working through updating from 12.2.12/luminious to 14.2.2/nautilus on centos 7.6. The managers are updated alright: # ceph -s cluster: id: 2fdb5976-1234-4b29-ad9c-1ca74a9466ec health: HEALTH_WARN Degraded data redundancy: 24177/9555955 objects degraded (0.253%), 7 pgs degraded, 1285 pgs undersized 3 monitors have not enabled msgr2 ... I updated ceph on a OSD host with 'yum update' and then rebooted to grab the current kernel. Along the way, the contents of all the directories in /var/lib/ceph/osd/ceph-*/ were deleted. Thus I have 16 OSDs down from this. I can manage the undersized but I'd like to get these drives working again without deleting each OSD and recreating them. So far I've pulled the respective cephx key into the 'keyring' file and populated 'bluestore' into the 'type' files but I'm unsure how to get the lockboxes mounted to where I can get the OSDs running. The osd-lockbox directory is otherwise untouched from when the OSDs were deployed. Is there a way to run ceph-deploy or some other tool to rebuild the mounts for the drives? peter _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com<https://nam02.safelinks.protection.outlook.com/?url=http%3A%2F%2Flists.ceph.com%2Flistinfo.cgi%2Fceph-users-ceph.com&data=02%7C01%7Cpeter.eisch%40virginpulse.com%7Ccb996f99f71d41410beb08d7106bece7%7Cb123a16e892b4cf6a55a6f8c7606a035%7C0%7C0%7C636995928035463289&sdata=ik8alrbkhnw%2BfJQhPd5TKI0vptcrHrl8Gp59yzu3OPY%3D&reserved=0>
