August 2019 - Dev - lists.ceph.io

by Brad Hubbard

Hello all, For the last couple of weeks I've been doing Coverity scans and posting them with the results from the other static analysis I do each week [1] I wanted to bring everyone up to speed on the current status and why I'm doing it this way. Quite some time ago now I took over the task of running the Coverity scans but in January last year they stopped working with the version that Coverity shipped and they have not worked since then with any publicly available version. this coincided with our move to C++11 and my investigation led me to believe that the version of Coverity current at teh time lacked support for c++1*. My company does have a subscription however and that gives us access to several versions which are not publicly available. I tested with various versions and found one that works and that is what I'm using to do the scans currently. Unfortunately Coverity's website (dashboard) does not support the uploading of results gathered with any version other than what they ship publicly so we are stuck with the HTML results I generate and host. I will be creating bug reports for the errors seen during scanning with the publicly available version (which is a *later* version than the working version) but how much priority they will be given I have no idea. Previous attempts to contact support have fallen on deaf ears so I'm not overly optimistic but we shall see. It has taken considerable time and effort to get to this point but various individuals have stated the importance of having these results available so it has been, and remains, a priority for me as do the other weekly scans I perform.

Can I remove cephfs_data pool when using cephFS mode (mimic 13.2)

by Valentin Bajrami

Hi everyone, When I started setting up a test cluster, I created a cephfs_data pool since I thought I was going to use the replicated type for the pool. This turned out not to be to most ideal choice when it comes to usable disk space. So I decided to create another erasure coded pool with k=2;m=2 which I did. Please see the attached log file. I also attached the output of the pools from the dashboard. The problem is this. Whenever an OSD needs to be brought down, the cluster is going to rebalance and enter the degraded mode. The rebalance of the cluster takes a while since all the PG's need to be redistributed. Now I could use something like: |ceph osd ||set| |noout && ceph osd ||set| |norebalance| However, I want to be able to have the cluster recovered much faster but cephfs_data pool which has a lot of PG's which I cannot reduce (not able in mimic) is keeping the cluster busy. This pool isn't used for storing any data and I am not sure if I can remove this pool without effecting the th-ec22 EC pool. Anyone any thoughs on this? In case I provided insufficient or missing information, please let me know. I'd gladly share those with you. -- Met vriendelijke groeten, Kind regards Valentin Bajrami Target Holding

CDM today!

by Sage Weil

1630 UTC / 12:30 ET / 9:30 PT https://bluejeans.com/908675367 Agenda: - [Josh] Unified osd admin commands. You can talk to daemons with 'ceph daemon <name> ...' and 'ceph tell <name> ...', but the command sets are annoyingly disjoint. - [Junior] progress module progress. Lots of work has been going into making good progress events (progress bars for interesting cluster events). Status update and discussion of next steps. - [Adam] RADOS client refactor. An effort to refactor librados, partly/primarily to support boost::asio for RGW, is nearing completion. Status update, review of goals, overview of design, performance, etc. Sorry for the late notice on this one! Hope to see you all in a few hours. sage

intermittend problem with the new ceph::mutex

by Willem Jan Withagen

Hi Kefu, Can you take a look at: http://cephdev.digiware.nl:8180/jenkins/job/ceph-master/3614/consoleFull And see if you can figure out why fails. It does so on and off when run from jenkins. If I use ctest from the commandline it just completes with no errors. Or I expect some extra debugging stuff possible in the Class, given some of the names in the backtrace.... Thanx, --WjW
