Change in vdsm[master]: vm: allow live snapshot to any volume descendant
by Federico Simoncelli 23 Jun '14

23 Jun '14

Federico Simoncelli has uploaded a new change for review. Change subject: vm: allow live snapshot to any volume descendant ...................................................................... vm: allow live snapshot to any volume descendant When a live snapshot fails qemu might not be using the newly-created leaf and the volume cleanup is at management discrection (sometime too risky or even impossible). In this particular situation (active layer not being the volume leaf) a subsequent live snapshot would have failed as the baseVolumeID was not the expected one. This patch relaxes the volumes checks allowing a live snapshot on the volume leaf even when it's not the direct descendant of the current active layer. Similarly also the check in hotunplugDisk has been relaxed so that it's now possible to hotunplug a disk with a failed live snapshot.

Change in vdsm[master]: Move fencing logic out of API.py

23 Jun '14

Saggi Mizrahi has uploaded a new change for review. Change subject: Move fencing logic out of API.py ...................................................................... Move fencing logic out of API.py API.py should not contain logic. In this patch I also: - Separate the `status` action to a different function because it does something completely different from the other action and has different logic. - Refactor for better code reusability readability. - Use real exception internally and have the API layer translate them to actual exceptions. - Don't support port strings in methods, just in the interface. - Don't support string booleans in the methods, just in the interface. - Added shutdownEvent to ClientIF so there is a public standard way of inspecting vdsm shutdown. - Make the fencing logic use betterPopen Change-Id: I944c6548a42612f705a410fb4290215451bca035 Signed-off-by: Saggi Mizrahi <smizrahi(a)redhat.com> --- M vdsm.spec.in M vdsm/API.py M vdsm/Makefile.am M vdsm/clientIF.py 4 files changed, 25 insertions(+), 72 deletions(-) git pull ssh://gerrit.ovirt.org:29418/vdsm refs/changes/90/7190/1 diff --git a/vdsm.spec.in b/vdsm.spec.in index 23afd6b..f122cb5 100644 --- a/vdsm.spec.in +++ b/vdsm.spec.in @@ -558,6 +558,7 @@ %{_datadir}/%{vdsm_name}/caps.py* %{_datadir}/%{vdsm_name}/clientIF.py* %{_datadir}/%{vdsm_name}/API.py* +%{_datadir}/%{vdsm_name}/fenceAgent.py* %{_datadir}/%{vdsm_name}/hooking.py* %{_datadir}/%{vdsm_name}/hooks.py* %{_datadir}/%{vdsm_name}/libvirtev.py* diff --git a/vdsm/API.py b/vdsm/API.py index ae04e01..5826d81 100644 --- a/vdsm/API.py +++ b/vdsm/API.py @@ -19,12 +19,9 @@ # import os -import signal import copy -import subprocess import pickle import time -import threading import logging from vdsm import utils @@ -40,6 +37,7 @@ from vdsm.define import doneCode, errCode, Kbytes, Mbytes import caps from vdsm.config import config +import fenceAgent import supervdsm @@ -981,82 +979,32 @@ agent is one of (rsa, ilo, drac5, ipmilan, etc) action can be one of (status, on, off, reboot).""" - def waitForPid(p, inp): - """ Wait until p.pid exits.
