Re: [ceph-users] ceph 9.2.0 mds cluster went down and now constantly crashes with Floating point exception

Hi, In my attempt to retry, I ran 'ceph mds newfs' because removing the fs was not working (because the mdss could not be stopped). With the new fs, I could again start syncing. After 10-15min it all crashed again. The log now shows some other stacktrace. -9> 2016-02-05 15:26:29.015197

Hi Zoltan, thanks for the answer. Because replacing hdfs:// with ceph:// and use CephFs doesn't work for all haddop componentes out of the box (unless in my tests), for example I had issues with Hbase, then with Yarn, Hue, etc (I'm using the cloudera distribution but I also tried with

Re: [ceph-users] cls_rbd ops on rbd_id.$name objects in EC pool

It seems like the cache tier should force promote when it gets an op the backing pool doesn't support. I think using the cache-pin mechanism would make sense. -Sam On Fri, Feb 5, 2016 at 7:53 AM, Jason Dillaman wrote: > #1 and #2 are awkward for existing pools since we

Re: [ceph-users] cls_rbd ops on rbd_id.$name objects in EC pool

#1 and #2 are awkward for existing pools since we would need a tool to inject dummy omap values within existing images. Can the cache tier force-promote it from the EC pool to the cache when an unsupported op is encountered? There is logic like that in jewel/master for handling the proxied

[ceph-users] Unified queue in Infernalis

I saw the following in the release notes for Infernalis, and I'm wondering where I can find more information about it? * There is now a unified queue (and thus prioritization) of client IO, recovery, scrubbing, and snapshot trimming. I've tried checking the docs for more details, but didn't have

[ceph-users] CFQ changes affect Ceph priority?

Not sure how many folks use the CFQ scheduler to use Ceph IO priority, but there’s a CFQ change that probably needs to be evaluated for Ceph purposes. http://lkml.iu.edu/hypermail/linux/kernel/1602.0/00820.html This might be a better question for the dev list. Warren Wang This email and any

Cullen, We operate a cluster with 4 nodes, each has 2xE5-2630, 64gb ram, 10x4tb spinners. We've recently replaced 2xm550 journals with a single p3700 nvme drive per server and didn't see the performance gains we were hoping for. After making the changes below we're now seeing significantly better

Re: [ceph-users] Unified queue in Infernalis

I believe this is referring to combining the previously separate queues into a single queue (PrioritizedQueue and soon to be WeightedPriorityQueue) in ceph. That way client IO and recovery IO can be better prioritized in the Ceph code. This is all before the disk queue. Robert LeBlanc Sent from
