PG calculate for cluster with a huge small objects

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello.

We have a cluster, 32 OSD, 80Tb usage space, FireFly 0.80.9 release.

This cluster we use for RBD and RadosGW Object storage witch our Openstack.

The data pools (Volumes, compute, images) are fine, but .rgw pool use 101Mb space and
have _462446_ objects. Average size an object in this pool is just 4.2k.

If we just will be increase PG/PGP num for this pool we stuck to limit a PGP number per
OSD after some time.

What we will do? Count of objects are increasing, space - a few.

What we living witch cluster of huge small size objects? Any suggestion?
