openmpdk / kvceph Goto Github PK

From your documents, I found KV-PM983 SSDs were used in KVCeph testing.
But I only found PM983 SSDs from retail stores, I can't sure PM983 SSDs can support or not.
https://www.samsung.com/semiconductor/global.semi/file/resource/2019/05/Product_Brief_Samsung_PM983_NF1_NVMe_SSD_1806.pdf

I did the following commands. After executing the last command, the system stopped responding and died.

./bin/ceph osd pool create rbd 64
./bin/ceph osd pool application enable rbd rbd
./bin/rbd pool init rbd
./bin/ceph auth get-or-create client.rbd mon 'allow *' osd 'allow *'
//last command.
./bin/rbd create block-disk1 --size 10240 --image-feature layering --id rbd

Cephfs and object types are expected to be available for KVSSD. Is it possible to implement rbd on KVSSD?

I add the necessary information for debugging as follows:
