Is downgrade supported? There are 2 aspects for that: - QE scenario as shown above - Customers that upgrade a zstream VDSM that brings out a problem in their setup, they may want to downgrade it. I have instructed Dafna to open this BZ just to bring up the discussion and get PM's response. I think that a GSS KB is enough. Should it be tested by QE ? Andrew ? Miki ? (In reply to comment #2) > There are 2 aspects for that: > - QE scenario as shown above > - Customers that upgrade a zstream VDSM that brings out a problem in their > setup, they may want to downgrade it. The problem is more complicated then that, since if the customer used re-install the host to upgrade the host then there may be other packaged that may have been upgraded including libvirt. Roll back should be done for all in this case or old VDSM may not work properly - right? I need answer here. I don't think this should be supported. Downgrade should be done using full bootstrap procedure. Barak, please assign to me when we have some answer. I think this should not be supported. |
Created attachment 611428 [details] logs Description of problem: I am testing upgrade from 3.0 cluster to 3.1 after upgrading the vdsm I decided to downgrade and rerun the vdsm upgrade so I ran yum downgrade vdsm when vdsm came back up it cannot communicate with libvirt with the below error: MainThread::ERROR::2012-09-10 16:06:06,512::vdsm::74::vds::(run) Traceback (most recent call last): File "/usr/share/vdsm//vdsm", line 72, in run serve_clients(log) File "/usr/share/vdsm//vdsm", line 40, in serve_clients cif = clientIF.clientIF(log) File "/usr/share/vdsm/clientIF.py", line 92, in __init__ self._libvirt = libvirtconnection.get() File "/usr/share/vdsm/libvirtconnection.py", line 94, in get conn = libvirt.openAuth('qemu:///system', auth, 0) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 102, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: authentication failed: Failed to collect auth credentials Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. install vdsm vdsm-4.9-113.3.el6_3.x86_64 2. upgrade to 4.9.6-32.0.el6_3 3. restart vdsm 4. run yum downgrade vdsm Actual results: when vdsm starts we cannot comunicate to libvirt with: authentication failed: Failed to collect auth credentials Expected results: we should be able to connect to libvirt Additional info: attaching vdsm logs and libvirt_password files. I tried restarting libvirt/vdsm and the host. looking at cd /etc/pki/vdsm/keys/ I can see two files: libvirt_password.rpmnew libvirt_password.rpmsave both have the correct password.
