Export Domain Lock File
by Nicholas Vaughan 15 May '18

15 May '18

Hi, Is there a lock file on the Export Domain which stops it being mounted to a 2nd instance of oVirt? We have a replicated Export Domain in a separate location that we would like to mount to a backup instance of oVirt for DR purposes. Thanks in advance. Nick

Gluster quorum
by Demeter Tibor 15 May '18

15 May '18

Dear Ovirt Users, I've followed up the self-hosted-engine upgrade documentation, I upgraded my 4.1 system to 4.2.3. I upgaded the first node with yum upgrade, it seems working now fine. But since upgrade, the gluster informations seems to displayed incorrect on the admin panel. The volume yellow, and there are red bricks from that node. I've checked in console, I think my gluster is not degraded: root@n1 ~]# gluster volume list volume1 volume2 [root@n1 ~]# gluster volume info Volume Name: volume1 Type: Distributed-Replicate Volume ID: e0f568fa-987c-4f5c-b853-01bce718ee27 Status: Started Snapshot Count: 0 Number of Bricks: 3 x 3 = 9 Transport-type: tcp Bricks: Brick1: 10.104.0.1:/gluster/brick/brick1 Brick2: 10.104.0.2:/gluster/brick/brick1 Brick3: 10.104.0.3:/gluster/brick/brick1 Brick4: 10.104.0.1:/gluster/brick/brick2 Brick5: 10.104.0.2:/gluster/brick/brick2 Brick6: 10.104.0.3:/gluster/brick/brick2 Brick7: 10.104.0.1:/gluster/brick/brick3 Brick8: 10.104.0.2:/gluster/brick/brick3 Brick9: 10.104.0.3:/gluster/brick/brick3 Options Reconfigured: transport.address-family: inet performance.readdir-ahead: on nfs.disable: on storage.owner-uid: 36 storage.owner-gid: 36 performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.stat-prefetch: off performance.low-prio-threads: 32 network.remote-dio: enable cluster.eager-lock: enable cluster.quorum-type: auto cluster.server-quorum-type: server cluster.data-self-heal-algorithm: full cluster.locking-scheme: granular cluster.shd-max-threads: 8 cluster.shd-wait-qlength: 10000 features.shard: on user.cifs: off server.allow-insecure: on Volume Name: volume2 Type: Distributed-Replicate Volume ID: 68cfb061-1320-4042-abcd-9228da23c0c8 Status: Started Snapshot Count: 0 Number of Bricks: 3 x 3 = 9 Transport-type: tcp Bricks: Brick1: 10.104.0.1:/gluster2/brick/brick1 Brick2: 10.104.0.2:/gluster2/brick/brick1 Brick3: 10.104.0.3:/gluster2/brick/brick1 Brick4: 10.104.0.1:/gluster2/brick/brick2 Brick5: 10.104.0.2:/gluster2/brick/brick2 Brick6: 10.104.0.3:/gluster2/brick/brick2 Brick7: 10.104.0.1:/gluster2/brick/brick3 Brick8: 10.104.0.2:/gluster2/brick/brick3 Brick9: 10.104.0.3:/gluster2/brick/brick3 Options Reconfigured: nfs.disable: on performance.readdir-ahead: on transport.address-family: inet cluster.quorum-type: auto network.ping-timeout: 10 auth.allow: * performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.stat-prefetch: off performance.low-prio-threads: 32 network.remote-dio: enable cluster.eager-lock: enable cluster.server-quorum-type: server cluster.data-self-heal-algorithm: full cluster.locking-scheme: granular cluster.shd-max-threads: 8 cluster.shd-wait-qlength: 10000 features.shard: on user.cifs: off storage.owner-uid: 36 storage.owner-gid: 36 server.allow-insecure: on [root@n1 ~]# gluster volume status Status of volume: volume1 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick 10.104.0.1:/gluster/brick/brick1 49152 0 Y 3464 Brick 10.104.0.2:/gluster/brick/brick1 49152 0 Y 68937 Brick 10.104.0.3:/gluster/brick/brick1 49161 0 Y 94506 Brick 10.104.0.1:/gluster/brick/brick2 49153 0 Y 3457 Brick 10.104.0.2:/gluster/brick/brick2 49153 0 Y 68943 Brick 10.104.0.3:/gluster/brick/brick2 49162 0 Y 94514 Brick 10.104.0.1:/gluster/brick/brick3 49154 0 Y 3465 Brick 10.104.0.2:/gluster/brick/brick3 49154 0 Y 68949 Brick 10.104.0.3:/gluster/brick/brick3 49163 0 Y 94520 Self-heal Daemon on localhost N/A N/A Y 54356 Self-heal Daemon on 10.104.0.2 N/A N/A Y 962 Self-heal Daemon on 10.104.0.3 N/A N/A Y 108977 Self-heal Daemon on 10.104.0.4 N/A N/A Y 61603 Task Status of Volume volume1 ------------------------------------------------------------------------------ There are no active volume tasks Status of volume: volume2 Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick 10.104.0.1:/gluster2/brick/brick1 49155 0 Y 3852 Brick 10.104.0.2:/gluster2/brick/brick1 49158 0 Y 68955 Brick 10.104.0.3:/gluster2/brick/brick1 49164 0 Y 94527 Brick 10.104.0.1:/gluster2/brick/brick2 49156 0 Y 3851 Brick 10.104.0.2:/gluster2/brick/brick2 49159 0 Y 68961 Brick 10.104.0.3:/gluster2/brick/brick2 49165 0 Y 94533 Brick 10.104.0.1:/gluster2/brick/brick3 49157 0 Y 3883 Brick 10.104.0.2:/gluster2/brick/brick3 49160 0 Y 68968 Brick 10.104.0.3:/gluster2/brick/brick3 49166 0 Y 94541 Self-heal Daemon on localhost N/A N/A Y 54356 Self-heal Daemon on 10.104.0.2 N/A N/A Y 962 Self-heal Daemon on 10.104.0.3 N/A N/A Y 108977 Self-heal Daemon on 10.104.0.4 N/A N/A Y 61603 Task Status of Volume volume2 ------------------------------------------------------------------------------ There are no active volume tasks I think ovirt can't read valid informations about gluster.

Ovirt Cpu pinning and Oracle database license with hardware partitioning.

Ovirt supports CPU pinning. So can I use this virtualizer to do partitioning hardware to save Oracle database licenses? Has any of you already done it?

Re: Scheduling a Snapshot of a Gluster volume not working within Ovirt
by Mark Betham 15 May '18

15 May '18

Hi Sahina, Many thanks for your response and apologies for my delay in getting back to you. > How was the schedule created - is this using the Remote Data Sync Setup under Storage domain? Ovirt is configured in ‘Gluster’ mode, no VM support. When snapshotting we are taking a snapshot of the full Gluster volume. To configure the snapshot schedule I did the following; Login to Ovirt WebUI From left hand menu select ‘Storage’ and ‘Volumes' I then selected the volume I wanted to snapshot by clicking on the link within the ‘Name’ column From here I selected the ‘Snapshots’ tab From the top menu options I selected the drop down ‘Snapshot’ From the drop down options I selected ‘New’ A new window appeared titled ‘Create/Schedule Snapshot’ I entered a snapshot prefix and description into the available fields and selected the ‘Schedule’ page On the schedule page I selected ‘Minute’ from the ‘Recurrence’ drop down Set ‘Interval’ to every ’30’ minutes Changed timezone to ‘Europe/London=(GMT+00:00) London Standard Time’ Left value in ‘Start Schedule by’ at default value Set schedule to ‘No End Date’ Click 'OK' Interestingly I get the following message on the ‘Create/Schedule Snapshot’ page before clicking on OK; Frequent creation of snapshots would overload the cluster Gluster CLI based snapshot scheduling is enabled. It would be disabled once volume snapshots scheduled from UI. What is interesting is that I have not enabled 'Gluster CLI based snapshot scheduling’. After clicking OK I am returned to the Volume Snapshots tab. From this point I get no snapshots created according to the schedule set. At the time of clicking OK in the WebUI to enable the schedule I get the following in the engine log; 2018-05-14 09:24:11,068Z WARN [org.ovirt.engine.core.dal.job.ExecutionMessageDirector] (default task-128) [85d0b16f-2c0c-464f-bbf1-682c062a4871] The message key 'ScheduleGlusterVolumeSnapshot' is missing from 'bundles/ExecutionMessages' 2018-05-14 09:24:11,090Z INFO [org.ovirt.engine.core.bll.gluster.ScheduleGlusterVolumeSnapshotCommand] (default task-128) [85d0b16f-2c0c-464f-bbf1-682c062a4871] Before acquiring and wait lock 'EngineLock:{exclusiveLocks='[712da1df-4c11-405a-8fb6-f99aebc185c1=GLUSTER_SNAPSHOT]', sharedLocks=''}' 2018-05-14 09:24:11,090Z INFO [org.ovirt.engine.core.bll.gluster.ScheduleGlusterVolumeSnapshotCommand] (default task-128) [85d0b16f-2c0c-464f-bbf1-682c062a4871] Lock-wait acquired to object 'EngineLock:{exclusiveLocks='[712da1df-4c11-405a-8fb6-f99aebc185c1=GLUSTER_SNAPSHOT]', sharedLocks=''}' 2018-05-14 09:24:11,111Z INFO [org.ovirt.engine.core.bll.gluster.ScheduleGlusterVolumeSnapshotCommand] (default task-128) [85d0b16f-2c0c-464f-bbf1-682c062a4871] Running command: ScheduleGlusterVolumeSnapshotCommand internal: false.

I had spent some time troubleshooting the issue but felt it worthwhile to ensure I had a clean platform, void of any potential issues which may be there due to some of the previous work carried out. The platform was rebuilt and data re-ingested. It is probably worth mentioning that this environment will become our new production platform, we will be migrating data and services to this new platform from our existing Gluster storage cluster. The date for the migration activity is getting closer so available time has become an issue and will not permit another full rebuild of the platform without impacting delivery date. > > After the rebuild with both storage clusters online, available and managed within the Ovirt platform I conducted some basic commissioning checks and I found no issues.

At this point the data re-ingestion was started and the new data was synchronised by the Geo-replication. > > The first step in bringing the snapshot schedule online was to validate that snapshots could be taken outside of the scheduler. Taking a manual snapshot via the OVirt portal worked without issue. Several were taken on both primary and secondary clusters. At this point a schedule was created on the primary site cluster via the Ovirt portal to create a snapshot of the storage at hourly intervals. The schedule was created successfully however no snapshots were ever created. Examining the logs did not show anything which I believed was a direct result of the faulty schedule but it is quite possible I missed something. > > How was the schedule created - is this using the Remote Data Sync Setup under Storage domain? > > > I reviewed many online articles, bug reports and application manuals in relation to snapshotting. There were several loosely related support articles around snapshotting but none of the recommendations seemed to work. I did the same with manuals and again nothing that seemed to work. What I did find were several references to running snapshots along with geo-replication and that the geo-replication should be paused when creating. So I removed all existing references to any snapshot schedule, paused the Geo-repl and recreated the snapshot schedule. The schedule was never actioned and no snapshots were created. Removed Geo-repl entirely, remove all schedules and carried out a reboot of the entire platform. When the system was fully back online and no pending heal operations the schedule was re-added for the primary site only.
