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

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!!! IMPORTANT: ONCE SHARDING IS ENABLED, IT CANNOT BE DISABLED !!! Best Regards,Strahil Nikolov? On Mon, Jun 5, 2023 at 13:55,

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.

Hi everybody Regarding the issue with mount, usually I am using this systemd service to bring up the mount points: /etc/systemd/system/glusterfsmounts.service [Unit] Description=Glustermounting Requires=glusterd.service Wants=glusterd.service After=network.target network-online.target glusterd.service [Service] Type=simple RemainAfterExit=true ExecStartPre=/usr/sbin/gluster volume list

On oVirt / Redhat Virtualization, the following Gluster volumes settings are recommended to be applied (preferably at the creation of the volume) These settings are important for data reliability, ( Note that Replica 3 or Replica 2+1 is expected ) performance.quick-read=off performance.read-ahead=off performance.io-cache=off performance.low-prio-threads=32 network.remote-dio=enable

Try turn off this options: performance.write-behind performance.flush-behind --- Gilberto Nunes Ferreira (47) 99676-7530 - Whatsapp / Telegram Em sex., 2 de jun. de 2023 ?s 07:55, Guillaume Pavese < guillaume.pavese at interactiv-group.com> escreveu: > On oVirt / Redhat Virtualization, > the following Gluster volumes settings are recommended to be applied > (preferably at

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 all, At some point recently my customers can no longer see GPFS snapshots under the Windows Previous Versions tab. It simply says "No previous versions available". If a fileset is exported with the flag "force user = root" then Previous Versions *are* displayed. [2016/07/06 10:07:35.602080, 3] ../source3/smbd/vfs.c:1322(check_reduced_name) check_reduced_name:

Hi, I have a ZFS dataset that has sync writes disabled (setting sync=disabled) which means that it will only do async writes, and sync requests get converted to async writes. The ZFS dataset is hosted on a single Samsung 840 Pro 512GB SATA SSD. I have this same dataset served as a Samba share, using Proxmox VE 6. Samba version 4.9.5-Debian (Buster), protocol SMB3_11. Kernel version 5.0.15. To

Hi, I have rebuilt samba3x SRPM in Centos 5.5. The resultings RPM's are nearly in triple size of the original RPMs. I have installed and checked the binary files are stripped. What can result in such difference in RPM sizes? I have not changed anything on built and install sections of spec file.

Hi All, I am facing issues restarting the gluster volume. When I start the volume after stopping it, the gluster fails to start the volume Below is the message that I get on CLI /root> gluster volume start _home volume start: _home: failed: Commit failed on localhost. Please check the log file for more details. Logs says that it was unable to start the brick [2013-08-08

I know nothing about ZFS, but that sounds like a mighty dangerous > setting for production deployments. Yes, you are correct - sync writes will flush to RAM, just like async, will stay in RAM for

Hello, We have a cluster with two nodes, "sg" and "br", which were running GlusterFS 9.1, installed via the Ubuntu package manager. We updated the Ubuntu packages on "sg" to version 9.6, and now have big problems. The "br" node is still on version 9.1. Running "gluster volume status" on either host gives "Error : Request timed out". On

Hello, I am using the vfs_gpfs samba module to map ACLs through samba. It works fine on files, but directory ACLs are ignored. Ex: getfacl /sb/share/myplace/ file: sb/share/myplace/ owner: root group: root user::rwx user:afrankel:rwx group::--- mask::rwx other::--- When I try to access this folder in Windows, I get permission denied. The same permissions on a files, I can open it / modify it

Dear R-list, I am wondering how to perform a bootstrap in R for the weighted time dependent Cox model? (Andersen?Gill format, with multiple observations from each patients) to obtain the bootstrap standard error of the treatment effect. Below is an example dataset. Would 'censboot' be appropriate to use in this context? Any suggestions/references/direction to R-package will be highly

Hi All, I'm having a frustrating time exporting a GPFS Independent Writer AFM fileset through Samba. Native GPFS directories exported through Samba seem to work properly, but when creating an export which points to an AFM IW fileset, I get "Access Denied" errors when trying to create files from an SMB client and even more unusual "Failed to enumerate objects in the container:
