Hi,
I would like to ask if anybody knows how to handle the gwcli status below.
- Disks state in gwcli shows as "Unknowm"
- Clients still mounting the "Unknown" disks and seems working normally.
Two of the rbd disks show "Unknown" instead of "Online" in gwcli.
.

performance.)
Since Ceph Octopus no longer fully supports CentOS 7. I am targeted to
migrate the Ceph cluster from CentOS 7 to CentOS 8 or Ubuntu.

Hi,
I had configured a cache tier with max object counts 500k. But no evict
happens when the object counts hit the configured maximum.
Anyone experienced this issue? What should I do?
$ ceph health detail
HEALTH_WARN 1 cache pools at or near target size
CACHE_POOL_NEAR_FULL 1 cache pools at or
everyone especially Eugen.

Hi,
The numbers of object counts from "rados df" and "rados ls" are different
in my testing environment. I think it maybe some zero bytes or unclean
objects since I removed all rbd images on top of it few days ago.
How can I make it right / found out where are those ghost objects? Or i
should

Hi,
I had configured a cache tier with below parameters:
cache_target_dirty_ratio: 0.1
cache_target_dirty_high_ratio: 0.7
cache_target_full_ratio: 0.9
The cache tier did improved the performance much. And I am targeted to keep
the cache tier with only 10% of dirty data. Remaining data ( 80% )
