Simple issue I cant find with the cache tier. Thanks for taking the time… Setup a new cluster with ssd cache tier. My cache tier is on 1TB ssd. With 2 replicas. It just fills up my cache until the ceph filesystem stops allowing access. I even set the target_max_bytes to 1048576 (1GB) and still d

Re: [ceph-users] Stat speed for objects in ceph

In librados getting a stat is basically equivalent to reading a small object; there's not an index or anything so FileStore needs to descend its folder hierarchy. If looking at metadata for all the objects in the system efficiently is important you'll want to layer an index in somewhere. -Greg On

[ceph-users] Stat speed for objects in ceph

Hi, As a general observation, the speed of calling stat() on any object in ceph is relatively slow. I'm probably getting a rate of about 10K per second using AIO, and even then it is really *really* bursty, to the point where there could be 5 seconds of activity going in one direction, then the c

Hi, In fact, when you increase your pg number, the new pgs will have to peer first and during this time, a lot a pg will be unreachable. The best way to upgrade the number of PG of a cluster (you 'll need to adjust the number of PGP too) is : - Don't forget to apply Goncalo advices to keep yo
