[ovirt-users] Re: oVirt upgrade version from 4.2 to 4.3
I would recommend you to postpone your upgrade if you use gluster (without the API) , as creation of virtual disks via UI on gluster is having issues - only preallocated can be created.

[ovirt-users] Re: [ovirt-announce] Re: [ANN] oVirt 4.3.4 First Release Candidate is now available
Ok,
so it seems that Darell's case and mine are different as I use vdo.
Now I have destroyed Storage Domains, gluster volumes and vdo and recreated
again (4 gluster volumes on a single vdo).This time vdo has '--emulate512=true'
and no issues have been observed.
Gluster volume options before 'Optimize for virt':
Volume Name: data_fast
Type: Replicate
Volume ID: 378804bf-2975-44d8-84c2-b541aa87f9ef
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: gluster1:/gluster_bricks/data_fast/data_fast
Brick2: gluster2:/gluster_bricks/data_fast/data_fast
Brick3: ovirt3:/gluster_bricks/data_fast/data_fast (arbiter)

transport.address-family: inet
nfs.disable: on
performance.client-io-threads: off
cluster.enable-shared-storage: enable
Gluster volume after 'Optimize for virt':
Volume Name: data_fast
Type: Replicate
Volume ID: 378804bf-2975-44d8-84c2-b541aa87f9ef
Status: Stopped

network.ping-timeout: 30
performance.strict-o-direct: on
storage.owner-gid: 36
storage.owner-uid: 36
server.event-threads: 4

After that adding the volumes as storage domains (via UI) worked without any
issues.
Can someone clarify why we have now 'cluster.choose-local: off' when in oVirt
4.2.7 (gluster v3.12.15) we didn't have that ?I'm using storage that is faster
than network and reading from local brick gives very high read speed.

We should have the following options:
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.locking-scheme=granular cluster.shd-max-threads=8
cluster.shd-wait-qlength=1 features.shard=on user.cifs=off
By the way the 'virt' gluster group disables 'cluster.choose-local' and I think
it wasn't like that.
Any reasons behind that , as I use it to speedup my reads, as local storage is
faster than the network?

OK,
Can we summarize it:
1. VDO must 'emulate512=true'
2. 'network.remote-dio' should be off ?
As per this:
https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3/html/configuring_red_hat_openstack_with_red_hat_storage/sect-setting_up_red_hat_storage_trusted_storage_pool
We should have these:
quick-read=off
read-ahead=off
io-cache=off
stat-prefetch=off
eager-lock=enable
remote-dio=on
quorum-type=auto
server-quorum-type=server
I'm a little bit confused here.

According to the user reports, this configuration is not compatible with oVirt.
Was this tested?
Yes, this is set by default in all test configuration. We’re checking on the
bug, but the error is likely when the underlying device does not support 512b
writes. With network.remote-dio off gluster will ensure o-direct writes

Ok, setting 'gluster volume set data_fast4 network.remote-dio on' allowed me

[ovirt-users] Virtual office, how?
I'm trying to be able to create different virtual LANs, where, for example, I have 2 groups of pcs A and B belongs to network N1 C and D belongs to network N2 N1 and N2 with his own public IP. For example A: Local ip: 192.168.122.100 B: Local ip: 192.168.122.101 C: Local ip: 192.168.122.102 D: Local ip: 192.168.122.103 Where A and B has the same public ip, and C and D has the same public ip. Now, I want that A can ssh on B, but not on C or D. The same goes for C, where C can access to D via ssh but not to A or B I'm not sure if OVS solve this problem or not, or if this is not possible. Is this possible?

[ovirt-users] newbie questions about installation using synology NAS
I'm starting fairly fresh. Ovirt engine 4.3.3.7 on a host 2 nodes installed with ovirt-release-host-node-4.3.3.1 synology DS418 with 5 TB disks I've configured the master engine and am ready to add the nodes. My questions have to do with the order or steps . Do I need to mount /volume1/data/images/rhev from the DS418 on each of the nodes before I add them or do I just add the nodes, then define a domain using the NFS mounts from the DS418?

Hi Add your nodes to oVirt then add your storage. Don't try to manually control the storage, let oVirt do that.

Define the nodes and when you create your NFS storage domain - it will be automatically mounted on all hosts in the DC.
