[ceph-users] Ceph-objectstore-tool import failure

I was able to bring a server back online for a short time and perform an export of the incomplete PGs I originally posted about last week. The export showed the files it was exporting and then dropped them all to a PGID.export file. I then SCP'ed the four PGID.export files to a server where I

Re: [ceph-users] Ceph-objectstore-tool import failure

It's not simply a zip. I recently went through an incomplete pg incident as well. I'm not sure why your import is failing, but I do know that much. Here's a note in slack from our effort to reverse the export. I'm hoping to explore this a bit more in the next week. Data frames appear to have the

[ceph-users] Have I configured erasure coding wrong ?

I followed the announcement of Luminous and erasure coding when I configured my system. Could this be the reason why my pool overloads when I push to much data at it ? root@pve:/#  ceph osd erasure-code-profile get ec-42-profile crush-device-class=hdd crush-failure-domain=osd crush-root=default

There are some documented issues with bluestore and jemalloc. At the moment, I would avoid it. On Jan 13, 2018 5:43 PM, "Marc Roos" wrote: > > I was thinking of enabling this jemalloc. Is there a recommended procedure > for a default centos7 cluster? > > > >

I regularly read the opposite here, and was thinking of switching to ec. Are you sure about what is causing your poor results. http://ceph.com/community/new-luminous-erasure-coding-rbd-cephfs/ http://ceph.com/geen-categorie/ceph-pool-migration/ ___

I was thinking of enabling this jemalloc. Is there a recommended procedure for a default centos7 cluster? ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

Re: [ceph-users] Switching a pool from EC to replicated online ?

didnt test with luminous i am still using kraken. but for normal RBD workload using EC with cache tier does not give give good results at all this pool has been running for few months with real users and while in testing it seems somehow ok and usable (still slow) in real workset it is very

Re: [ceph-users] Switching a pool from EC to replicated online ?

You cannot change a pool between EC and replicated. There is no migration path between the two without creating a new pool. You can't even change the EC profile of an EC pool after it's created. On Sat, Jan 13, 2018, 7:00 PM mofta7y wrote: > didnt test with luminous i am
