hi, folks! I'm testing cache tier for erasure coded pool and with
RBD image on it. And now I'm facing a problem with full cache pool
and object are not evicted automatically, Only if I run manually
rados -p cache cache-flush-evict-all*
client side is:
superuser@share:~$ uname
Hi,
you need to set the max dirty bytes and/or max dirty objects as these 2
parameters will default to 0 for your cache pool.
ceph osd pool set cache_pool_name target_max_objects x
ceph osd pool set cache_pool_name target_max_bytes x
The ratios you already set (dirty_ratio = 0.4 and
Thanks a lot to /*Be-El*/ from #ceph (irc://irc.oftc.net/ceph)
The problem is resolved after setting 'target_max_bytes' for cache pool:
*$ ceph osd pool set cache target_max_bytes 1840*
Because setting only 'cache_target_full_ratio' to 0.7 - is not
sufficient for cache tiering agent,
