[Gluster-users] Two VMS as arbiter...

Well...
I do the follow:

gluster vol create VMS replica 3 arbiter 1 pve01:/DATA/brick1
pve02:/DATA/brick1.5 pve01:/DATA/arbiter1.5 pve02:/DATA/brick2 pv
e01:/DATA/brick2.5 pve02:/DATA/arbiter2.5 force

And now I have:
gluster vol info

Volume Name: VMS
Type: Distributed-Replicate
Volume ID: 1bd712f5-ccb9-4322-8275-abe363d1ffdd
Status: Started
Snapshot Count: 0
Number of Bricks: 2 x (2 + 1) = 6
Transport-type: tcp
Bricks:
Brick1: pve01:/DATA/brick1
Brick2: pve02:/DATA/brick1.5
Brick3: pve01:/DATA/arbiter1.5 (arbiter)
Brick4: pve02:/DATA/brick2
Brick5: pve01:/DATA/brick2.5
Brick6: pve02:/DATA/arbiter2.5 (arbiter)
Options Reconfigured:
cluster.quorum-count: 1
cluster.quorum-reads: false
cluster.self-heal-daemon: enable
cluster.heal-timeout: 10
storage.fips-mode-rchecksum: on
transport.address-family: inet
nfs.disable: on
performance.client-io-threads: off

This values I have put it myself, in order to see if could improve the time
to make the volume available, when pve01 goes down with ifupdown
cluster.quorum-count: 1
cluster.quorum-reads: false
cluster.self-heal-daemon: enable
cluster.heal-timeout: 10

Nevertheless, it took more than 1 minutes to the volume VMS available in
the other host (pve02).
Is there any trick to reduce this time ?

Thanks
