hello
one of our OSD crashed, unfortunately it had a a unreplicated pool
(size = 1).
i want to recover as much as possible using raw files, i've tried using
this tool
https://raw.githubusercontent.com/smmoore/ceph/4eb806fdcc02632bf4ac60f302c4e1ee3bef6363/rbd_restore.sh
but i don't found any file rb.0.1938.f8e1ca65f7a.*
# rbd -p cinder-simple info volume-e1dbb182-24b1-4729-a398-e494fe037678
rbd image 'volume-e1dbb182-24b1-4729-a398-e494fe037678':
size 300 GB in 76800 objects
order 22 (4096 kB objects)
block_name_prefix: rbd_data.1938f8e1ca65f7a
format: 2
features: layering
i beth on disk structure has changed, can anybody shed some light on how
is it now? i'm using plain XFS ceph 0.72.2 (emperor)
That script refers to format 1 rbd image object names (rb.x.y.z.*).
Just use the block_name_prefix reported by rbd info instead, in this
case rbd_data.1938f8e1ca65f7a, and it should work fine.
