Objet: [ovirt-users] Re: Disk (brick) failure on my stack

I'm not sure about the GUI (but I think it has the option) , but under command line you got several options.


1. Use gluster's remove-brick replica 2 (with flag force)
and then 'add-brick replica 3'
2. Use the old way 'replace-brick'

If you need guidance, please provide the 'gluster volume info <VOLUME>' .

Best Regards,

yesterday I had a disk failure on my stack of 3 Ovirt 4.4.1 node

on each server I have 3 Bricks (engine, data, vmstore)

brick data 4X600Gig raid0. /dev/gluster_vg_sdb/gluster_lv_data mount /gluster_bricks/data
brick engine 2X1TB raid1 /dev/gluster_vg_sdc/gluster_lv_engine mount /gluster_bricks/engine
brick vmstore 2X1TB raid1 /dev/gluster_vg_sdc/gluster_lv_vmstore mount /gluster_bricks/vmstore

Everything was configured by the gui (hyperconverge and hosted-engine)

It is the raid0 of the 2nd server who broke.

all VMs were automatically moved to the other two servers, I haven't lost any data.

the host2 is now in maintenance mode.

I am going to buy 4 new SSD disks to replace the 4 disks of the defective raid0.

When I'm going to erase the faulty raid0 and create the new raid with the new disks on the raid controler, how do I add in ovirt so that they resynchronize with the other bricks data?
