Hello,
What kind of topology do you have between your replicas ? Maybe you have
a congestion between them which results as a timeout on file creation.
While on the topic I would love to know where is the mounting command of
glusterfs into PVE architecture ?
It can be very useful to tweak the mounting options like relatime or
atime to increase performance.
Regards

Hi there,
I'm having several problems with using gluster as a storage. I'm using a
gluster replica 2 between two buildings, the connection is 10Gb.
I can access gluster and write so far so good. But when using proxmox the
problems arise...
I cannot upload iso files (I think I've readed on the forum that its a bug) and
in fact it's a minor issue.
The problem comes when I want to create a VM. It takes a long time (I guess
depending the hard disk size) and if I try to access via ssh when it is trying
to create the VM, when I cd to the glusterfs mountpoint it seems to be stalled
(I cannot do a double-tab for autocomplete the name, for instance).
After a while, the GUI shows,
TASK ERROR: create failed - unable to create image: got lock timeout - aborting
command
I can create the VM on a local storage (I didn't try a NFS share, iSCSI or
another network destination) flawlessly, and then move the disk to the gluster
storage without problems.
I can even mount via FUSE the gluster and the I CAN create the VM on it (but it
is considered then a local storage and I cannot do a live migration, etc).
So, there is any problem with replicas? I tried on a distributed-only gluster
on the lab and it worked perfect, but on my client's house I'm facing this...
Any idea?
I can post any log if you want, but I would also know your experience with this
scenario. I have quite experience with gluster, so I'm pretty sure that this
gluster is working as it should.
Thank you everyone,
Angel Docampo
