vdsm log showing the error
Version of vdsm used: vdsm-4.17.0-33.git92f3d7f.el7ev.x86_64 Text of the original post to users at ovirt.org @ 14-12-2015 12:00 I have reinstalled my test environment have come across an old error, see BZ 988299, Bad volume specification {u'index': 0,. At the end of that BZ there is mentioning of a problem with '_' in the name of the volume and a patch is mentioned but the code has since been change quite a bit and I can't find if that still applies. It look like it doesn't because I have a gluster volume with the name gv_ovirt_data01 and it look like it gets translated to gv__ovirt__data01 and then I can't start any VMs Weird thing, I CAN import VMs from the export domain to this gluster domain. Followup mail: I have just done the following on 2 servers which also hold the volumes with '_' in it: mkdir -p /gluster/br-ovirt-data02 ssm -f create -p vg_`hostname -s` --size 10G --name lv-ovirt-data02 --fstype xfs /gluster/br-ovirt-data02 echo /dev/mapper/vg_`hostname -s`-lv-ovirt-data02 /gluster/br-ovirt-data02 xfs defaults 1 2 >>/etc/fstab semanage fcontext -a -t glusterd_brick_t /gluster/br-ovirt-data02 restorecon -Rv /gluster/br-ovirt-data02 mkdir /gluster/br-ovirt-data02/gl-ovirt-data02 chown -R 36:36 /gluster/ Added a replicated volume on top of the above, started it, added a Storage Domain using that volume, moved a disk to it, and started the VM, works! In vdsm-4.16.X it isn't a problem because I have one hosted-engine setup with that version and a underscore in the volume name. The command to check for gluster volumes is different though: /usr/sbin/gluster --mode=script volume info --xml and in vdsm-4.17.X its: /usr/sbin/gluster --mode=script volume info --remote-host=st01.nieuwland.nl gv__ovirt__data01 --xml Hi Joop, The code that fails seems to be related to a patch (https://gerrit.ovirt.org/44061) that isn't merged to any branch. Actually, this patch wasn't tested nor verified. Basically, there should be no issues with volume names that include underscores in their names. Is vdsm-4.17.X build that you tried a private build? Can you try same scenarios using a stable branch? Thanks! It looks like a private build was indeed used. Can't replicate it at the moment so this can be closed Joop |
