extras: disable lookup-optimize in virt and block groups (#2254)

2021-03-17T09:59:54+00:00

lookup-optimize doesn't provide any benefit for virtualized
environments and gluster-block workloads, but it's known to cause
corruption in some cases when sharding is also enabled and the volume
is expanded or shrunk.

For this reason, we disable lookup-optimize by default on those
environments.

extras: Modify group 'virt' to include network-related options

2020-05-04T09:00:57+00:00

This is needed to work around an issue seen where vms running on
online hosts are getting killed when a different host is rebooted
in ovirt-gluster hyperconverged environments. Actual RCA is quite
lengthy and documented in the github issue. Please refer to it
for more details.

extras: Enable direct-io options in group virt

2019-09-11T09:27:29+00:00

Direct-io options are currently enabled in the ovirt-gluster
installation through cockpit ui whereas all the other optimizations in
gluster for virt are enabled through the group-virt option using
'volume-set' command. For the sake of completeness and to avoid any
confusion, it would be better to set the o-direct gluster options also
as part of group virt.

extras: Add new options to group "virt"

2018-09-19T10:19:27+00:00

In some of the recent performance tests on gluster-as-vm-image-store
use-case, it has been observed that sometimes the lone fuse thread can
hit near-100% CPU utilization and become a performance bottleneck.
Enabling client-io-threads (in addition to bumping up epoll threads on
server and client side) has shown to be helpful in getting around this
bottleneck and pushing more IOPs.

extras: Enable stat-prefetch in virt profile

2017-07-06T08:55:09+00:00

In the internal testing that was done, stat-prefetch did help
reduce the number of stats coming from qemu hitting the disk,
and thereby improved performance.

extras: Add more options to group virt

2017-02-09T10:26:04+00:00

Apart from some of the option configurations already listed
in the group-virt.example file, we also recommend that the
users set certain other options added by this patch for
VM use-case. This also helps Gluster-oVirt users in configuring
virt options for new volumes at the click of a button as opposed
to setting them manually through volume-set command.

extras: Add namespace for options in group-virt.example

2016-04-09T01:59:53+00:00

Commit 23ccabbeb7 introduced a new key "disperse.eager-lock" which
causes a conflict with key "cluster.eager-lock" when option is used
without the qualifying namespace. group-virt.example which gets
installed as /var/lib/glusterd/ groups/virt contains options without
namespace qualifiers. This patch adds the appropriate namespace to all
options in group-virt.example.

group-virt: To minimize 'split-brain' enable quorum under virt profile

2013-11-22T09:37:33+00:00

Quorum as default is necessary when storing virtual machine images. It
would be necessary to enable both server and client quorum

Currently defaulted values are:
----------------
server-quorum-type=server
quorum-type=auto
----------------
