* extras: Enable direct-io options in group virtKrutika Dhananjay2019-10-081-1/+2
| | | | | | | | | | | | | 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"Krutika Dhananjay2018-09-211-0/+3
| | | | | | | | | | | | | 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 profileKrutika Dhananjay2017-07-101-1/+0
| | | | | | | | | | | | | | | 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 virtKrutika Dhananjay2017-02-171-2/+7
| | | | | | | | | | | | | | | | | | | 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.exampleVijay Bellur2016-04-091-8/+8
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | Quorum as default is necessary when storing virtual machine images.

* group-virt: Change profile to include remote-dio and exclude posix-aio.Vijay Bellur2013-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | remote-dio enables filtering O_DIRECT in the client xlator. This has been found to be useful for improving performance when there are multiple VMs talking to an image store. Aggregated throughput results for a single thread iozone run from multiple VMs and a single host can be seen below: ------------------------------------------------- No. of VMs | remote-dio on | remote-dio off | ------------------------------------------------- 2 | 400 MB/s | 202 MB/s | 4 | 650 MB/s | 410 MB/s | -------------------------------------------------- posix-aio has not been found to improve performance consistently with VM image workload. Hence not including that in the default virt profile.
