Re: Luminous OSD: replace block.db partition

[Igor Fedotov <ifedotov@xxxxxxx>]

Konstantin,

one should resize device  before using bluefs-bdev-expand command.

So the first question should be what's the backend for block.db - simple device partition, LVM volume, raw file?

LVM volume and raw file resizing is quite simple, while partition one might need manual data movement to another target via dd or something.

Thanks,

Igor

Hello - I have created an OSD with 20G block.db, now I wanted to change the
block.db to 100G size.
Please let us know if there is a process for the same.

PS: Ceph version 12.2.4 with bluestore backend.

You should upgrade to 12.2.11+ first! Expand your block.db via `ceph-bluestore-tool bluefs-bdev-expand --path /var/lib/ceph/osd/ceph-<osd.id>`
