Change in vdsm[master]: Enable VM migration to old vdsm's.
Dan Kenigsberg has posted comments on this change. Change subject: Enable VM migration to old vdsm's. .. Patch Set 2: (1 comment) Ayal, maybe I misunderstood the condition that worries you. If so, please re-explain it. I am a bit anxious to unbreak migration in ovirt-3.3 by promptly taking this patch. File vdsm/storage/blockSD.py Line 1035: try: Line 1036: os.symlink(imgPath, dst) Line 1037: except OSError as e: Line 1038: if e.errno == errno.EEXIST: Line 1039: self.log.debug(img run dir already exists: %s, dst) I tend to agree with Eduardo: the link source and destination contains the very same sdUUID. If someone called prepareImage() with sdUUID, we are bound to return a path to that domain, even though a newer image exists on another domain. In such a case, the bug exists higher in the stack, with whomever asked to prepare the image on the stale storage domain.

Patch Set 2: Code-Review-1 (1 comment) File vdsm/storage/blockSD.py Line 1035: try: Line 1036: os.symlink(imgPath, dst) Line 1037: except OSError as e: Line 1038: if e.errno == errno.EEXIST: Line 1039: self.log.debug(img run dir already exists: %s, dst) What? I have a stale link there to the wrong image dir (from a previous run VM which wasn't cleaned because host crashed or whatever) and since then user ran liveStorageMigration and moved the disk to a new sd. I think this is a bug. Also, this is not runVM context, we're in blockSD Please fix Line 1040: else: Line 1041: self.log.error(Failed to create img run dir: %s, dst) Line 1042: raise Line 1043: return dst -- To view, visit http://gerrit.ovirt.org/19825 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: comment Gerrit-Change-Id: Ia778ad743a11b4c1d212857d8f25c81eb4c0defe Gerrit-PatchSet: 2 Gerrit-Project: vdsm Gerrit-Branch: master Gerrit-Owner: Eduardo ewars...@redhat.com Gerrit-Reviewer: Ayal Baron aba...@redhat.com Gerrit-Reviewer: Dan Kenigsberg dan...@redhat.com Gerrit-Reviewer: Eduardo ewars...@redhat.com Gerrit-Reviewer: Gadi Ickowicz gicko...@redhat.com Gerrit-Reviewer: Yeela Kaplan ykap...@redhat.com Gerrit-Reviewer: oVirt Jenkins CI Server Gerrit-HasComments: Yes ___ vdsm-patches mailing list vdsm-patches@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-patches
Change in vdsm[master]: Enable VM migration to old vdsm's.
Eduardo has posted comments on this change. Change subject: Enable VM migration to old vdsm's. .. Patch Set 2: (1 comment) File vdsm/storage/blockSD.py Line 1035: try: Line 1036: os.symlink(imgPath, dst) Line 1037: except OSError as e: Line 1038: if e.errno == errno.EEXIST: Line 1039: self.log.debug(img run dir already exists: %s, dst) Stale link to where? There are not too many dst that can be there. Link to the image are created by other functions too and the net result is the same, linking the block image. This method is only called from vm.py. Running again the same VM, activating the dame SD/image, will result in the same link. In the case you described, you are talking about removing something that we don't know what is, assuming that is engine trying to run a VM with an image that is not (but was) in this SD. This is a serious engine bug, and it should be solved in the LSM. Having the same image UUID in two SDs, only engine can determine which is the correct one.
