Using glusterfs for virtual machines with qcow2 images
Hi Chris, here is a link to the settings needed for VM storage: https://github.com/gluster/glusterfs/blob/03592930239c3b43cbbdce17607c099ae075fd6d/extras/group-virt.example#L4 You can also ask in ovirt-users for real-world settings.Test well before changing production!!!

Using glusterfs for virtual machines with qcow2 images
Chris: Whilst I don't know what is the issue nor the root cause of your issue with using GlusterFS with Proxmox, but I am going to guess that you might already know that Proxmox "natively" supports Ceph, which the Wikipedia article for it says that it is a distributed object storage system. Maybe that might work better with Proxmox? Hope this helps. Sorry that I wasn't able

We use qcow2 with libvirt based kvm on many small clusters and have found it to be exremely reliable though maybe not the fastest, though some of that is most of our storage is SATA SSDs in a software RAID1 config for each brick.

Using glusterfs for virtual machines with qcow2 images
Hi, we'd like to use glusterfs for Proxmox and virtual machines with qcow2 disk images. We have a three node glusterfs setup with one volume and Proxmox is attached and VMs are created, but after some time, and I think after much i/o is going on for a VM, the data inside the virtual machine gets corrupted. When I copy files from or to our glusterfs directly everything is OK, I've

Centos 8 and xfs_quota
Folks I'm trying to use xfs_quota to keep track of disk space usage for my users. The documentation states that I should specify "uquota" as an option on the mount data in /etc/fstab. Yet, I cannot find the entry in fstab that corresponds to the Logical Volume that ends up being mounted on /home1. The system in question was installed on a single disk system. Later, after

[EXT] [Glusterusers] Using glusterfs for virtual machines with qco
Hi Gilberto, hi all, thanks a lot for all your answers. At first I changed both settings mentioned below and first test look good. Before changing the settings I was able to crash a new installed VM every time after a fresh installation by producing much i/o, e.g. when installing Libre Office. This always resulted in corrupt files inside the VM, but researching the qcow2 file with the

Hi Gluster users, We are seeing 'error=No space left on device' issue and hoping someone might could advise?

Gluster rebalance taking many years
Hi, This value is an ongoing rough estimate based on the amount of data rebalance has migrated since it started. The values will cange as the rebalance progresses. A few questions: 1. How many files/dirs do you have on this volume? 2. What is the average size of the files? 3. What is the total size of the data on the volume? Can you send us the rebalance log? Thanks, Nithya On 30

Help on aggregate method
Dear R experts, I would really appreciate if you had an idea on how to use more efficiently the aggregate method: More specifically, I would like to calculate the mean of certain values on a data frame,? grouped by various attributes, and then create a new column in the data frame that will have the corresponding mean for every row. I attach part of my code: matchMean <-
