主 题 ：[ceph-users] using devices class when creating a pool
Hi All,
I'm trying to use the devices class feature while creating the pool, but no luck.
I see the following section in the CRUSH map, but I can't find any documentation showing how to use it!
# devices
device 0 osd.0 class hdd
device 1 osd.1 class hdd
device 2 osd.2 class ssd
.
.
.
How to create a pool using certain filters (e.g. storage class, buckets, rack, etc...)?
Regards,
Bishoy Mikhael
