I should add, we are not using cephadm. From: Bruno Canning Sent: 23 May 2024 11:36 To: ceph-users@xxxxxxx Subject: Pacific 16.2.15 and ceph-volume no-longer creating LVM on block.db partition Hi Folks, After recently upgrading from 16.2.13 to 16.2.15, when I run: ceph-volume lvm create --data /dev/sda --block.db /dev/nvme0n1p1 to create a new OSD after replacement of a failed disk, ceph-volume no-longer creates a volume group/logical volume on the block.db partition*. This is the old behaviour we saw whilst running Octopus but we have not seen this since our upgrade to Pacific until now. Any ideas why this is happening? Nothing is jumping out of the release notes, but they do mention a lot of work was done on the LVM code in ceph-volume since 16.2.13. Is this now a configuration setting somewhere? Background: Our storage nodes are 60 HDDs per chassis with two 2TB NVMe drives, each containing 30 partitions used as block.db storage, one partition and one HDD per OSD. We are running Ubuntu 20.04 and Ceph Pacific 16.2.15, just upgraded from 16.2.13. We are using the official Ubuntu packages. *so /var/lib/ceph/osd/ceph-1090/block.db points to /dev/nvme0n1p1 and not /dev/ceph-11992480-4ea6-4c1a-80b0-e025a66539b2/osd-db-52655aa3-9102-4d92-8a63-f2c93eed984f which would be on /dev/nvme0n1p1 ---------------------------------------------------------------------- The Wellcome Sanger Institute is operated by Genome Research Limited, a charity registered in England with number 1021457 and a company registered in England with number 2742969, whose registered office is Wellcome Sanger Institute, Wellcome Genome Campus, Hinxton, CB10 1SA. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
