[ceph-users] CloudRuntimeException: Failed to create storage pool

Hello, I have created a ceph cluster with one admin server, one monitor and two osd's. The setup is completed. But when trying to add the ceph as primary storage of cloudstack, I am getting the below error in error logs. Am I missing something ? Please help. 2017-02-20

yes, https://www.sebastien-han.fr/blog/2014/08/25/ceph-mix-sata-a nd-ssd-within-the-same-box/ is enough don't test on your production env. before you start, backup your cursh map. ceph osd getcrushmap -o crushmap.bin below's some hint: ceph osd getcrushmap -o crushmap.bin crushtool -d

Re: [ceph-users] Rbd export-diff bug? rbd export-diff generates different incremental files

Hi Jason, Thanks for the reply. We are not sure this issue is only occurring on cloned images. We think it would be a generic synchronization issue. Our production/test setup are all based on Hammer, so we don’t have a chance to touch Jewel. But we will try Jewel latter. We don’t use cache

Re: [ceph-users] Jewel + kernel 4.4 Massive performance regression (-50%)

Hello, Just a quick update since I didn't have time for this yesterday. I did a similar test as below with only the XFS node active and as expected results are opposite: 3937 IOPS 3.16 3595 IOPS 4.9 As opposed to what I found out yesterday: --- Thus I turned off the XFS node and ran the test

Re: [ceph-users] Experience with 5k RPM/archive HDDs

Hi, again, as I said, in normal operation everything is fine with SMR. They perform well in particular for large sequential writes because of the on platter cache (20 GB I think). All tests we have done were with good SSDs for OSD cache. Things blow up during backfill / recovery because the

Thanks! Seems non-standard, but it works. :) C. Anyone know what's wrong? You can clear these by setting them to zero. John Everything is Jewel 10.2.5. Thanks! Chad. ___ ceph-users mailing list ceph-users@lists.ceph.com

Re: [ceph-users] Rbd export-diff bug? rbd export-diff generates different incremental files

AFAIK, that fix is scheduled to be included in Hammer 0.94.10 (which hasn't been released yet). Is this issue only occurring on cloned images? Since Hammer is nearly end-of-life, can you repeat this issue on Jewel? Are the affected images using cache tiering? Can you determine an

Hi, everyone. I read the source code. Could this be a case: a "WRITE" op designated to OBJECT X is followed by a series of Ops at the end of which is a "READ" op designated to the same OBJECT that come from the "rbd EXPORT" command; although the "WRITE" op modified the ObjectContext of OBJECT

Re: [ceph-users] Rbd export-diff bug? rbd export-diff generates different incremental files

Could this be a synchronization issue in which case multi clients visiting the same object, one client(the vm/qemu) is updating the object while another client(ceph rbd export/export-diff execution) is reading the content of the same object? How do Ceph make sure the consistency in this case?
