Thanks aaron, very much for the continued help it provided a lit path in the darkness.... It has been two weeks of 50% trial and error and 50% iterative planned improvement. We tried everything aaron suggested and more; however, as aaron stated, HDD's are, after all, HDDs and we were never...

Thanks Aaron, so we increased out pg's to 128 based on the calculator and current percentage of us. Of course with the autoscaler it dropped it back down to 32. So we have set the autoscaler to warn and its overbalancing. after we will run more tests. We still see over 50% wa and some time as...

Ok i have confirmed that our switches can support 9214 bytes and have updated all the configs for the private network on all Ppve hosts. Thanks aaron for all the recommendations. We still do seem to have some good news and some bad. We still see iowa states at 3-12, then to 0 with the server...

It is actually doing a balance at the moment. its been going for about to hours: Recovery/ Rebalance: 96.31% (14.58 MiB/s - 1h 23m 28.7s left)

I did just check our old cluster and it is also at 1500, one noticeable difference ids there is 0/0 apply/commit latency where as the new cluster is between 20-60 with the average being around 30

latency all round is between .1 - .23 ms

I have asked if the provider switch support jumbo frames, our current net conf is at 1500

Thank you for the assistance i hope this helps. We provider did tell us that the ssd were enterprise/datacenter drives and it s reputable hosting provider, although the storage engineers had no real experience with ceph.

Hi Everyone, We have a constant write (4-10MBs, total) application with ~ 120 vm's and burned though ssd's in just under 2 years with our dedicated hosting provider so they recommended we got back to spindles. We have built 5 new servers as follows: high core count, 256G RAM, 480 SSD for the...

After running deep scrubs and enabling balancing all of the errors are now gone and the cluster is in good health. I'm still relatively sure this is not an OSB setup as I have read there may be better ways to organize buckets? but again my experience with ceph is hours old. I'm going to start...

Hi, We have the following servers mentioned below, they can not be changed as we are using MaaS and they are configured this way. I realize this is not optimal but would prefer to spend time on figuring out what can work with this hardware layout and how can we leverage what we have. I am not...
