You don't need to do it manually, there is a an option in Admin portal
-> Storage -> Volumes -> Select Volume -> "three dots in upper right"
-> Optimize for Virt Store

[ovirt-users] Re: For data integrity make sure that the server is configured with Quorum (both client and server Quorum)

2021-01-21 Thread tommy 
I get the current setting:

 

[root@gluster1 ~]# gluster volume info all

 

Volume Name: volume1

Type: Disperse

Volume ID: 237f7379-cd03-44ef-af39-f6065d01d520

Status: Started

Snapshot Count: 0

Number of Bricks: 1 x (2 + 1) = 3

Transport-type: tcp

Bricks:

Brick1: gluster1:/data/glusterfs/myvolume/mybrick1/brick

Brick2: gluster2:/data/glusterfs/myvolume/mybrick1/brick

Brick3: gluster3:/data/glusterfs/myvolume/mybrick1/brick

Options Reconfigured:

transport.address-family: inet

nfs.disable: on

 

 

Then I enable the quorum on the server side:

 

[root@gluster1 ~]# gluster volume set all cluster.server-quorum-ratio 51%

volume set: success

[root@gluster1 ~]#

[root@gluster1 ~]# gluster volume set volume1 cluster.server-quorum-type server

volume set: success

[root@gluster1 ~]#

 

 

Now, the configure is :

 

[root@gluster1 ~]# gluster volume info volume1

 

Volume Name: volume1

Type: Disperse

Volume ID: 237f7379-cd03-44ef-af39-f6065d01d520

Status: Started

Snapshot Count: 0

Number of Bricks: 1 x (2 + 1) = 3

Transport-type: tcp

Bricks:

Brick1: gluster1:/data/glusterfs/myvolume/mybrick1/brick

Brick2: gluster2:/data/glusterfs/myvolume/mybrick1/brick

Brick3: gluster3:/data/glusterfs/myvolume/mybrick1/brick

Options Reconfigured:

cluster.server-quorum-type: server

transport.address-family: inet

nfs.disable: on

cluster.server-quorum-ratio: 51%

[root@gluster1 ~]#

 

 

I want know ,the server quorum is about setting the percen of numbers of the 
active-connected nodes,  no matter what type of the volumes , is this right ?

 

But if I use the client quorum, the the type of volumes now mounting is acting, 
only duplicated type volume can use the client quorum, is this right ?
