* 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.

* group-virt: To minimize 'split-brain' enable quorum under virt profileHarshavardhana2013-11-221-0/+2
| | | | | | | | | | | | | | | | | | 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 ---------------- Change-Id: Ic2adb5856ce3c2589476e872e988cae6eeb9b25e BUG: 1032080 Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/6340 Reviewed-by: Vijay Bellur <vbellur@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>
* 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.

* Added virt group file - template for 'group' setKrishnan Parthasarathi2012-12-111-0/+6
- This sample file contains the set of volume options that are associated with volumes that would be used to store VMs. - To enable the set of options present in this file one must do the following, - # cp extras/group-virt.example /var/lib/glusterd/groups/<group-name> # gluster volume set <volume-name> group <group-name> Change-Id: I8848d3d222ce114900db885aeef2f20c83ece28c BUG: 851237 Signed-off-by: Krishnan Parthasarathi <kparthas@redhat.com> Reviewed-on: http://review.gluster.org/4232 Reviewed-by: Anand Avati <avati@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>
