[ovirt-users] engine.log is looping with Volume XXX contains a apparently corrupt brick(s).

[Nico]

Hi 

Recently, i built a small oVirt platform with 2 dedicated servers and
GlusterFS to synch the VM storage. 

oVirt Setup is simple: 

ovirt01 : Host Agent (VDSM) + oVirt Engine 

ovirt02 : Host Agent (VDSM) 

Version : 

ovirt-release35-005-1.noarch 

ovirt-engine-3.5.4.2-1.el7.centos.noarch 

vdsm-4.16.26-0.el7.centos.x86_64 

vdsm-gluster-4.16.26-0.el7.centos.noarch 

glusterfs-server-3.7.4-2.el7.x86_64 

GlusterFS Setup is simple, 2 bricks in replicate mode. 

It was done in shell; not using oVirt GUI, and then it was added in
STORAGE as a new DOMAIN; Type:DATA GlusterFS V3 

# gluster volume info 

Volume Name: ovirt 

Type: Replicate 

Volume ID: 043d2d36-dc2c-4f75-9d28-96dbac25d07c 

Status: Started 

Number of Bricks: 1 x 2 = 2 

Transport-type: tcp 

Bricks: 

Brick1: ovirt01:/gluster/ovirt 

Brick2: ovirt02:/gluster/ovirt 

Options Reconfigured: 

performance.readdir-ahead: on 

nfs.disable: true 

auth.allow: IP_A, IP_B 

network.ping-timeout: 10 

storage.owner-uid: 36 

storage.owner-gid: 36 

server.allow-insecure: on 

the data are reachable on the 2 nodes through a moint point that oVirt
created when i configured the Storage with the GUI: 

localhost:/ovirt 306G 216G 78G 74%
/rhev/data-center/mnt/glusterSD/localhost:_ovirt 

I created 7 VM on this shared storage and all is working fine. I can do
Live migration; all is working. 

But when i check /var/log/ovirt/engine.log on ovirt01, there are error
in loop every 2 seconds: 

2015-10-11 17:29:50,971 INFO

(DefaultQuartzScheduler_Worker-29) [34dbe5cf] Volume ovirt contains a
apparently corrupt brick(s). Hence will not add it to engine at this
point. 

I played a lot with oVirt at first it was running on a single node; in
Local Datacenter; then i added a second node, move the first host to a
new datacenter; migrated the images VM etc; with some pain at some very
moment and now all looks fine but i prefer to double check. 

So, i want to know if there is a real issue with ovirt/gluster setup
that i don't see, any info are welcome because i'm a bit worried to see
these message in LOOP on the log. 

Thanks in advance; 

Regards 

Nico
