Change in vdsm[master]: dump the core of a domain
by shaohef＠linux.vnet.ibm.com 19 Oct '15

19 Oct '15

ShaoHe Feng has uploaded a new change for review. Change subject: dump the core of a domain ...................................................................... dump the core of a domain libvirt support an API to dump the core of a domain on a given file for analysis when guest OS crash. There are two kind of dump files. one is QEMU suspend to disk image. the other is core file which like kdump file butcontains registers' value. It's helpful to support by VDSM to find root cause if a guest gets hang and kdump isn't set up in it. This would be a good RAS feature. Here's the definition of the new API: coreDump: This method will dump the core of a domain on a given file for analysis. Input parameter: vmId - VM UUID to - the core file named by the user flags - defined in libvirt.py VIR_DUMP_CRASH VIR_DUMP_LIVE VIR_DUMP_BYPASS_CACHE VIR_DUMP_RESET VIR_DUMP_MEMORY_ONLY Return value: success: return doneCode failure: return errCode including underlying libvirt error message.

Change in vdsm[master]: Added gluster tag support in getAllTasks()
by barumuga＠redhat.com 14 Oct '15

14 Oct '15

Hello Ayal Baron, Timothy Asir, Saggi Mizrahi, Federico Simoncelli, Dan Kenigsberg, I'd like you to do a code review. Please visit http://gerrit.ovirt.org/7579 to review the following change. Change subject: Added gluster tag support in getAllTasks() ...................................................................... Added gluster tag support in getAllTasks() If param tag is empty, all tasks including gluster tasks are returned, else tasks those tags are in param tag list are returned. As below verbs are not consumed by engine/RHS-C yet, its OK to differ in compatibility issue now. glusterVolumeRebalanceStart glusterVolumeRebalanceStatus glusterVolumeReplaceBrickStart glusterVolumeReplaceBrickStatus glusterVolumeRemoveBrickStart glusterVolumeRemoveBrickStatus Change-Id: I9c765cbfebb5ba22f0d21efa04c824ea4daf6432 Signed-off-by: Bala.FA <barumuga(a)redhat.com> --- M tests/gluster_cli_tests.py M vdsm/gluster/cli.py M vdsm/gluster/exception.py M vdsm/storage/taskManager.py 4 files changed, 367 insertions(+), 95 deletions(-) git pull ssh://gerrit.ovirt.org:29418/vdsm refs/changes/79/7579/1 diff --git a/tests/gluster_cli_tests.py b/tests/gluster_cli_tests.py index f442893..9c6357c 100644 --- a/tests/gluster_cli_tests.py +++ b/tests/gluster_cli_tests.py @@ -28,6 +28,7 @@ from gluster import cli as gcli except ImportError: pass +import xml.etree.cElementTree as etree class GlusterCliTests(TestCaseBase): @@ -115,3 +116,74 @@ def test_parsePeerStatus(self): self._parsePeerStatus_empty_test() self._parsePeerStatus_test() + + def _parseVolumeStatusAll_test(self): + out = """<?xml version="1.0" encoding="UTF-8" standalone="yes"?> +<cliOutput> + <opRet>0</opRet> + <opErrno>0</opErrno> + <opErrstr></opErrstr> + <volumes> + <volume> + <name>V1</name> + <id>03eace73-9197-49d0-a877-831bc6e9dac2</id> + <tasks> + <task> + <name>rebalance</name> + <id>12345473-9197-49d0-a877-831bc6e9dac2</id> + </task> + </tasks> + </volume> + <volume> + <name>V2</name> + <id>03eace73-1237-49d0-a877-831bc6e9dac2</id> + <tasks> + <task> + <name>replace-brick</name> + <id>12345473-1237-49d0-a877-831bc6e9dac2</id> + <sourceBrick>192.168.122.167:/tmp/V2-b1</sourceBrick> + <destBrick>192.168.122.168:/tmp/V2-b1</destBrick> + </task> + </tasks> + </volume> + <volume> + <name>V3</name> + <id>03eace73-1237-1230-a877-831bc6e9dac2</id> + <tasks> + <task> + <name>remove-brick</name> + <id>12345473-1237-1230-a877-831bc6e9dac2</id> + <BrickCount>2</BrickCount> + <brick>192.168.122.167:/tmp/V3-b1</brick> + <brick>192.168.122.168:/tmp/V3-b1</brick> + </task> + </tasks> + </volume> + </volumes> +</cliOutput>""" + tree = etree.fromstring(out) + status = gcli._parseVolumeStatusAll(tree) + self.assertEquals(status, + {'12345473-1237-1230-a877-831bc6e9dac2': + {'bricks': ['192.168.122.167:/tmp/V3-b1', + '192.168.122.168:/tmp/V3-b1'], + 'taskType': 'remove-brick', + 'volumeId': + '03eace73-1237-1230-a877-831bc6e9dac2', + 'volumeName': 'V3'}, + '12345473-1237-49d0-a877-831bc6e9dac2': + {'bricks': ['192.168.122.167:/tmp/V2-b1', + '192.168.122.168:/tmp/V2-b1'], + 'taskType': 'replace-brick', + 'volumeId': + '03eace73-1237-49d0-a877-831bc6e9dac2', + 'volumeName': 'V2'}, + '12345473-9197-49d0-a877-831bc6e9dac2': + {'bricks': [], + 'taskType': 'rebalance', + 'volumeId': + '03eace73-9197-49d0-a877-831bc6e9dac2', + 'volumeName': 'V1'}}) + + def test_parseVolumeStatusAll(self): + self._parseVolumeStatusAll_test() diff --git a/vdsm/gluster/cli.py b/vdsm/gluster/cli.py index 95de106..1f464f6 100644 --- a/vdsm/gluster/cli.py +++ b/vdsm/gluster/cli.py @@ -84,6 +84,55 @@ raise ge.GlusterCmdFailedException(rc=rv, err=[msg]) +class TaskType: + REBALANCE = 'rebalance' + REPLACE_BRICK = 'replace-brick' + REMOVE_BRICK = 'remove-brick' + + +def _parseVolumeStatusAll(tree): + """ + returns {TaskId: {'volumeName': VolumeName, + 'volumeId': VolumeId, + 'taskType': TaskType, + 'bricks': BrickList}, ...} + """ + tasks = {} + for el in tree.findall('volumes/volume'): + volumeName = el.find('name').text + volumeId = el.find('id').text + for c in el.findall('tasks/task'): + taskType = c.find('name').text + taskId = c.find('id').text + bricks = [] + if taskType == TaskType.REPLACE_BRICK: + bricks.append(c.find('sourceBrick').text) + bricks.append(c.find('destBrick').text) + elif taskType == TaskType.REMOVE_BRICK: + for b in c.findall('brick'): + bricks.append(b.text) + elif taskType == TaskType.REBALANCE: + pass + tasks[taskId] = {'volumeName': volumeName, + 'volumeId': volumeId, + 'taskType': taskType, + 'bricks': bricks} + return tasks + + +@exportToSuperVdsm +def volumeStatusAll(): + command = _getGlusterVolCmd() + ["status", "all"] + try: + xmltree, out = _execGlusterXml(command) + except ge.GlusterCmdFailedException, e: + raise ge.GlusterVolumeStatusAllFailedException(rc=e.rc, err=e.err) + try: + return _parseVolumeStatusAll(xmltree) + except: + raise ge.GlusterXmlErrorException(err=out) + + def _parseVolumeInfo(out): if not out[0].strip(): del out[0] @@ -300,11 +349,15 @@ command.append("start") if force: command.append("force") -

Change in vdsm[master]: [WIP] Implement a process to do dangerous IO in C
by smizrahi＠redhat.com 23 Jun '14

23 Jun '14

Saggi Mizrahi has uploaded a new change for review. Change subject: [WIP] Implement a process to do dangerous IO in C ...................................................................... [WIP] Implement a process to do dangerous IO in C This replaces the process pool with a process that can serve multiple requests written in C. This implementation is much more scalable and lightweight. Should solve bugs related to running out of helpers, logging getting suck, python forking deadlocking, running out of memory and other things as well. The communication between VDSM and the IOProcess is done with json objects. The IOProcess starts with 3 thread: 1. requestReader - reads requests from the pipe, builds a DOM representation of it and queues it up for handling 2. responseWriter - gets response DOMs from the queue converts them to a JSON string and send it over the pipe 3. requestHandler - pops requests from the queue and provisions threads for handling them. Currently we I just allocate a new thread per request. If there is ever a need to have a thread pool this is where the load balancing is going to sit. Each request gets the are as a JsonNode and returns a response that is a JsonNode as well. Most exported functions are pretty trivial and are a good example on how to write new ones. Unlink the ProcessPoolHelper, high level commands sit of the OopWrapper and are run from the client side instead of being implemented in C on the IOProcess side.

Change in vdsm[master]: Move fencing logic out of API.py
by smizrahi＠redhat.com 23 Jun '14

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.
