Gluster users - May 2015 - Debian Jessie (8) qemu-kvm VM and glusterfs as backend storage

Hi,

Are there any issues with debian8 and glusterfs?


Got this setup:
1. promox 3.4
2. gluster 3.5.3 both server and client (I use gluster repo on proxmox
server)
3. HA gluster volume

What I'm trying to do:
task: create a VM with debian 8, using glusterfs HA volume over 1G network
as a place for VM disk file
result:
a) using raw file format - installation process takes ages (6 hours), but
when finished, VM looks weird: packages installations go slowly (downloads
fast, but installs slow). Same time getting files over internet gives me
usual speed (around 96MB/s, yes, I'm on 1G connection)
b) Using qcow format installation process randomly stops at random step:
getting packages from the repository or installing packages after
donwnloaded them ...

c) If i convert VM  with RAW file format to template and then create a VM
using this template, but selecting qcow format, VM runs smoothly.

Meanwhile, there are lots of VMs on the same gluster storage (debian7,
centos6, ubuntu) running without any problems.

I've started topic on proxmox forum, but devs saying, it should be upto
glusterfs :(

Any advice or experiences?


PS
installing deb8 on local storage goes well, without any problems.
installing deb7 on the same setup (same VM even, just another virtual
driver) is ok.

Best regards,
Roman.

Hey,


Seems like the problem exists.

I've got 4 instances of proxmox. I've started to update glusterfs some
day
to the latest (3.5.3) but I've done the server side and forgot about client
side. One of proxmox instances was replaced today and installed the 3.5.3
client. So the problem is between 3.5.3 server and 3.5.3 client. then I've
updated glusterfs on other proxmox node and had same problem with d8
install.

There is just no go with debian 8 install and qcow file format. If I use
raw file format for kvm, installation takes ages.

Need fix asap, as this is you stable gluster version... we are running this
on in production.
