Danti, Have you considered using something other than drbd for VM disk storage? Glusterfs for example is really good for that. You may want to give it a try. You should look at enabling sharding from the get-go to speed up heals when a node goes down. I would not use Glusterfs for a file server as it's performance is abysmal dealing with lots of small files. I would definitively use DRBD for a file server as it is great in handling lots of small files whereas Glusterfs is horrible. But for VMs, I think gluster offers many niceties, easy to setup, good performance, no need to deal with GFS2, etc. HTH, Diego ________________________________ From: drbd-user-bounces at lists.linbit.com <drbd-user-bounces at lists.linbit.com> on behalf of Gionatan Danti <g.danti at assyoma.it> Sent: Friday, August 25, 2017 3:37:41 PM To: Digimer Cc: drbd-user at lists.linbit.com Subject: Re: [DRBD-user] DRBD Dual Primary + GFS2 for redundant KVM hosts Il 25-08-2017 14:34 Digimer ha scritto: > > Our Anvil! project (https://www.alteeve.com/w/Build_an_m2_Anvil!) is > basically this, except we put the VMs on clustered LVs and use gfs2 to > store install media and the server XML files. > > I would NOT put the image files on gfs2, as the distributed locking > overhead would hurt performance a fair bit. Hi, I contemplated using an active/active lvm-based configuration, but I would really like to use files as per VM disks. So, do you feel GFS2 would be inadequate for VM disk storage? What if a node crashes/reboots? Will GFS2 continue to work?
