Hi ceph-users,
Hoping that this is something small that I am overlooking, but could use the
group mind to help.
Ceph 12.2.2, Ubuntu 16.04 environment.
OSD (0) is an 8TB spinner (/dev/sda) and I am moving from a filestore journal
to a blocks.db and WAL device on an NVMe partition (/dev/nvme0n1p5).
I have an OSD that I am trying to convert to bluestore and running into some
trouble.
Started here until the ceps-volume create statement, which doesn’t work.
http://docs.ceph.com/docs/master/rados/operations/bluestore-migration/
<http://docs.ceph.com/docs/master/rados/operations/bluestore-migration/>
Worth mentioning I also flushed the journal on the nvme partition before nuking
the OSD.
> $ sudo ceph-osd -i 0 --flush-journal
So I first started with this command:
> $ sudo ceph-volume lvm create --bluestore --data /dev/sda --block.db
> /dev/nvme0n1p5 --osd-id 0
Pastebin to the ceph-volume log: https://pastebin.com/epkM3aP6
<https://pastebin.com/epkM3aP6>
However the OSD doesn’t start.
Pastebin to ceph-osd log: https://pastebin.com/9qEsAJzA
<https://pastebin.com/9qEsAJzA>
I tried restarting the process, by deleting the LVM structures, zapping the
disk using ceph-volume.
This time using prepare and activate instead of create.
> $ sudo ceph-volume lvm prepare --bluestore --data /dev/sda --block.db
> /dev/nvme0n1p5 --osd-id 0
> $ sudo ceph-volume lvm activate --bluestore 0
> 227e1721-cd2e-4d7e-bb48-bc2bb715a038
Also ran the enable on the ceph-volume systemd unit per
http://docs.ceph.com/docs/master/install/manual-deployment/
<http://docs.ceph.com/docs/master/install/manual-deployment/>
> $ sudo systemctl enable ceph-volume@lvm-0-227e1721-cd2e-4d7e-bb48-bc2bb715a038
Same results.
Any help is greatly appreciated.
Thanks,
Reed
