Disk is virtio, alright! Because I need live migration and HA. With IDE/SATA there is no way to do that, AFAIK! 2015-10-29 11:07 GMT-02:00 Luis G. Coralle : > Disk virtio too? > > 2015-10-29 10:03 GMT-03:00 Gilberto Nunes : > >> I alredy

Re: [PVE-User] I try hard but...

I use NFSv4, and I've never had any problems. You have to hand modify the storage config file. I've used Ubuntu NFS servers with DRBD, and more recently, Synology boxes (again with DRBD). I also bond my network links for 2GB bandwidth. I'm not sure why Proxmox doesn't support NFSv4 out of

I didn't use OCFS, eithet XFS or EXT4. No need for OCFS unless you're dual primary. Maybe OCFS is doing something weird for you? Gerald On 2015-10-29 06:50 AM, Gilberto Nunes wrote: That's precisely my scenario... I have DRBD + OCFS and a gigaethernet cable link the two server. The server

Re: [PVE-User] I try hard but...

It could be, but it could be also that with IDE or SATA the performance is not the same as well with Virtio, or am I wrong??? 2015-10-29 12:14 GMT-02:00 Lindsay Mathieson : > > On 29 October 2015 at 23:09, Gilberto Nunes > wrote: > >>

Even with local storage? I thought that was one of the limitations of a node with that kind of setup. On Oct 29, 2015 10:14 AM, Lindsay Mathieson wrote: > > > On 29 October 2015 at 23:09, Gilberto Nunes > wrote: >> >> Disk is virtio,

Re: [PVE-User] I try hard but...

At least as of ~v3.4, you can live migrate IDE but not SATA. I've run into this a few times myself when I configured SATA CD-ROMs for some reason. -Adam On 15-10-29 09:14 AM, Lindsay Mathieson wrote: On 29 October 2015 at 23:09, Gilberto Nunes

[PVE-User] mixed linux bridges and openvswitch

Was working on implementing OVS within my 4 node cluster. Things did not go as planned (do they ever?) for reasons other than the issue below. Anyway, my condition is I'm down to going backwards and have 3 of the 4 nodes configured with linux bridge configuration vmbr0 and vmbr1 Node 3

Re: [PVE-User] mixed linux bridges and openvswitch

Ok works for me. So with this logic I should be able to shut down said machine, remove nics, migrate to other host. Then restart, replace nics/drivers. I think I have tried this, but just sounding off right now. Bit puzzled why vmbr0 worked on both.. just affected vmbr1. On 10/29/2015
