[ceph-users] Pool shard/stripe settings for file too large files?

Yes, I actually changed it back to the default after reading somewhat 
about it (https://github.com/ceph/ceph/pull/15520). I wanted to store 
5GB and 12GB files, that makes recovery not to nice. I thought there was 
a setting to split them up automatically like with rbd pools.

If you're running luminous you may need to increase osd_max_object_size. 
This snippet is from the Luminous change log.

"The default maximum size for a single RADOS object has been reduced 
from 100GB to 128MB. The 100GB limit was completely impractical in 
practice while the 128MB limit is a bit high but not unreasonable. If 
you have an application written directly to librados that is using 
objects larger than 128MB you may need to adjust osd_max_object_size"
