kata-irc-bot<bergwolf> Hello Kata wizards,  We have just release the latest stable 1.9.3 and cut RC 1.10.0-rc0.  The 1.9.3 stable release includes quite a few bug fixes most importantly the firecracker fix for CVE-2019-18960. All users are recommended to upgrade.  The 1.10.0-rc0 release candidate brings in even more changes, notably - cloud-hypervisor support - constraint kata host components at sandbox level - no more bridge network mode, tcfilter is the03:08
kata-irc-botdefault network mode now - nemu support is removed  We look forward to stabilizing it in the next few weeks. Kudus to all kata users and contributors!  Cheers, Tao03:08
kata-irc-bot<jiangzt> @manchenchen How is the test going?03:21
kata-irc-bot<simon.kaegi> Hi there, we're using 1.9.3 under K8s/containerd and it's generally working well for us however... on one of our hosts we install and mount a `gpfs` filesystem and in our pods create a hostPath volume. Sadly the path is not visible so the volume doesn't resolve and the pod is stuck. We're using more or less default settings for this particular install. Any suggestions?03:32

kata-irc-bot<graham.whaley> Hi @simon.kaegi - that's the IBM `gpfs` is it? I'm not sure we've seen anybody try to mount one of those into a Kata before (a search of github kata org returned nothing). It may be something that needs enabling or has discovered a gap - some info from the logs is going to be useful - I'll /cc @archana.m.shinde who might know which bits of which logs will help best. Thanks for raising the query!11:09

kata-irc-bot<simon.kaegi> Yes that's right re:gpfs. I'll try a few more things on my end and create the simplest version that illustrates the problem. I unfortunately (or maybe that's fortunately ;)) need to fully chase this down and so if there are gaps I'm happy to contribute. Any clues on where to start investigating are greatly appreciated.14:00
kata-irc-bot<graham.whaley> great @simon.kaegi. first, I'd probably enable all the debug in the kata config file, and then see if you can find any clues in the resulting logs for the failure.14:02
kata-irc-bot<graham.whaley> I don't know anything about `gpfs` - does it have any specific hardware requirements or distro dependancies? There are a couple of other IBM'ers (and RH folks) in the kata community, in case that might help. If you are not in touch with them already, shout, and we'll name and pull in ;)14:03

kata-irc-bot<simon.kaegi> Thanks @graham.whaley let me dig in and get some answers. Would it help to create an issue and continue the discussion there?14:26
kata-irc-bot<graham.whaley> @simon.kaegi np - absolutely, a github issue would be great (as we also then keep the history and can pull others in).14:28

kata-irc-bot<simon.kaegi> hrmm... actually when I went down to the simplest pod and tested things the mount worked just fine. Sorry it must be something like I get scheduled on the wrong node. But I can at least confirm gpfs mounts from the host work...16:33
kata-irc-bot<graham.whaley> cool, np!16:50
