Restricted access to /teuthology on teuthology.front.sepia.ceph.com

by Patrick Donnelly

Hi folks, As many of you are aware, RAM/CPU is particularly scarce on teuthology.front.sepia.ceph.com which means that any log viewing of QA results can cause swapping and general slowness. At today's Ceph Infrastructure Weekly call [1], I proposed only allowing root, www-data, and teuthworker access to /teuthology so that others would be forced to look at logs on other beefier development machines like senta [2], vossi [3], your personal workstation [4], or even some temporary locked node [5]. The current plan is to proceed barring some reasonable justification not to. There are a few to-do items to make it happen laid out in the minutes. Until then, admins of teuthology would appreciate it if you already start moving your log viewing to other machines without waiting for a technical barrier to be set up.

arrow submodule version

by Casey Bodley

hey Gal and Eric, in today's standup, we discussed the version of our apache arrow submodule. it's currently pinned at 6.0.1, which was tagged in nov. 2021. the centos9 builds are using the system package libarrow-devel-9.0.0. arrow's upstream recently tagged an 11.0.0 release as far as i know, there still aren't any system packages for ubuntu, so we're likely to be stuck with the submodule for quite a while. how do guys want to handle these updates? is it worth trying to update before the reef release?

Re: [ceph-users] Re: Debian/bullseye build for reef

by Josh Durgin

We weren't targeting bullseye once we discovered the compiler version problem, the focus shifted to bookworm. If anyone would like to help maintaining debian builds, or looking into these issues, it would be welcome: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1030129 https://tracker.ceph.com/issues/61845 On Mon, Aug 21, 2023 at 7:50 AM Matthew Darwin <bugs(a)mdarwin.ca> wrote: > Thanks for the link to the issue.

"issue pool application warning even if pool is empty" change

by Ilya Dryomov

Hello, What was the motivation for the "issue pool application warning even if pool is empty" change [1]? This didn't occur to me what I saw the PR, but it basically makes it impossible to create a pool without HEALTH_WARN popping up. The reason is that pool creation and pool application enablement are separate monitor commands: there is no way to create a pool and enable an application on a pool atomically. And this is why this health check has always been limited to in-use pools (also pointed out by Greg when it was being introduced [2]). [1] https://github.com/ceph/ceph/pull/47560 [2] https://github.com/ceph/ceph/pull/15763#discussion_r123084421 Thanks, Ilya

bluestore_compression_min_blob_size vs. bluestore_compression_min_blob_size_<type>

by Tony Liu

Hi, With Pacific and afterwards, which of the following two settings takes precedence? bluestore_compression_min_blob_size (default 0) bluestore_compression_min_blob_size_<type> (default 8192) I'd assume the more specific setting takes precedence? What's this "blob"? Is it write block? Then, there is no compression for 4K write block? I was not able to find it out from doc, hope someone could help to clarify. Thanks! Tony

rbd export with export-format 2 exports all snapshots?

by Tony Liu

Hi, Say, source image has snapshot s1, s2 and s3. I expect "export" behaves the same as "deep cp", when specify a snapshot, with "--export-format 2", only the specified snapshot and all snapshots earlier than that will be exported. What I see is that, no matter which snapshot I specify, "export" with "--export-format 2" always exports the whole image with all snapshots. Is this expected? Could anyone help to clarify? Thanks! Tony

rbd export-diff/import-diff hangs

by Tony Liu

Hi, I'm using rbd import and export to copy image from one cluster to another. Also using import-diff and export-diff to update image in remote cluster. For example, "rbd --cluster local export-diff ... | rbd --cluster remote import-diff ...". Sometimes, the whole command is stuck. I can't tell it's stuck on which end of the pipe. I did some search, [1] seems the same issue and [2] is also related. Wonder if there is any way to identify where it's stuck and get more debugging info. Given [2], I'd suspect the import-diff is stuck, cause rbd client is importing to the remote cluster. Networking latency could be involved here? Ping latency is 7~8 ms. Any comments is appreciated! [1] https://bugs.launchpad.net/cinder/+bug/2031897 [2] https://stackoverflow.com/questions/69858763/ceph-rbd-import-hangs Thanks! Tony
