Hi. I have got the same issue (filesystems read-only) when provisioning CentOS 6.5 as node host (installed base OS and added vdsm package). multipathd shows wwids file reaed-only. Cant't write wwid. Fore some reason filesystem gets corrupted when installing vdsm. Regards.

We need assistance watching time for the speakers, and helping with video for the devroom. Please contact Joe Brockmeier (jzb at redhat.com) for more information here. ------------------------- Details: READ CAREFULLY ------------------------- This year at FOSDEM there will be a one-day devroom to focus on IaaS projects. If your project is related to IaaS, we would love to see your submissions. Please note that we expect more proposals than we can possibly accept, so it is vitally important that you submit your proposal on or before the deadline. Late submissions are unlikely to be considered. All slots are 40 minutes, with 30 minutes planned for presentations, and 10 minutes for Q&A. All presentations *will* be recorded and made available under Creative Commons licenses. Please indicate when submitting your talk that your presentation will be licensed under the CC-By-SA-4.0 or CC-By-4.0 license when submitting the talk and that you agree to have your presentation recorded.

yappi rpm
by Saggi Mizrahi 27 Oct '14

27 Oct '14

As those of you that have been developing VDSM might know some time ago yappi profiling support was added to VDSM. This was a good idea but yappi has no fedora\el RPMs which forced each developer to find and download yappi from around the internet. Also, I personally don't like using disutils as there is no clean uninstall options (oddly enough). I am currently in the process of getting yappi into fedora. There are f21 RPMs (should work with older fedora and el) for you downloading/testing pleasure [1] Also, if you can, please help the package review process [2] [1] https://smizrahi.fedorapeople.org/yappi/ [2] https://bugzilla.redhat.com/1155495

Using libgfapi on Gluster Storage Domains
by Federico Simoncelli 23 Oct '14

23 Oct '14

Hi everyone, if you want to try and use the libgfapi support included in qemu when accessing volumes on gluster storage domains you can try to apply this patch: http://gerrit.ovirt.org/33768 As far as I know Jason Brooks already tried it and he reported a positive feedback. What has been tested so far is: - qemu uses libgfapi to access the disks on gluster storage domains - hotplug of disks on gluster storage domains works as expected (libgfapi) - hotunplug works as expected (no failure when removing a disk that is using libgfapi) - live snpashots work as expected - disks of vms started before this patch are not affected (they won't use libgfapi since there's no way to do an hot swap) One major flow that is yet untested is live storage migration. Remember that you may need to do some special configuration on your gluster volumes (most notably the allow-insecure ports option) as described here: http://www.ovirt.org/Features/GlusterFS_Storage_Domain Please try and test the patch if you're interested and report your feedback. Thanks, -- Federico

how (inefficient) does vdsm import sparse disks in local storage(file based) data domain?
by Sven Kieske 23 Oct '14

23 Oct '14

Hi, I might be totally mistaken, so please tell me first if I understand the process: when vdsm imports a template from an export domain to local storage, according to my "ps" output, vdsm copies sparse templates using "dd": vdsm 14378 0.3 0.0 59032 4424 ? S<l 14:43 0:05 \_ /usr/bin/qemu-img convert -t none -f raw /rhev/data-center/d6ec1bb0-43ce-4e09-9a7a-e54f9779af64/4ed22092-e961-4e04-b77b-2648ad21f83a/image vdsm 17291 0.0 0.0 8344 608 ? D< 15:14 0:00 \_ /bin/dd iflag=direct if=/rhev/data-center/mnt/$REDACTED:_home_iso/e7b8f2e2-b9f7-493c-96b5-33bfb091d0ba/dom_md/metadata bs=4096 count=1 If this is correct I have some questions regarding this behaviour: I understand that "dd" is "rock solid" works everywhere and for maybe every storage/format combination and thus was maybe chosen to do the work. But if I'm right and I have a 100 GB sparse disk which actually uses just 1 GB "dd" will copy the whole 100 GB over network, which is really not efficient at all. So here's my proposal (if I do not have any mistakes in the above): at least make a: tar -cpSvf disk.tar /path/to/disk and than "dd" this over the network, because tar _can_ handle sparse files. Of course any other more efficient mechanism would be okay too. If my observation is right, and the project think it's worth to implement such a thing I would create an RFE for this and I also would like to help code this (in my leisure time). PS: I did observe this behaviour on ancient ovirt 3.3 with vdsm version: vdsm-4.13.4-0.el6.x86_64 but I didn't see anything in release notes which changed this behaviour. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
