Im thinking about replacing my NAS with #Glusterfs. But I’m not sure about one usecase. My NAS serves NFS storage to a KVM host. On the NFS are qcow images. The performance isn’t great but perfectly acceptable for what I do. Would that still work with Glusterfs or would the constant sync of data in the background be too much?

Resolution of at a least some of this issue... Having nfs-kernel-server export glusterfs seems to be part of the issue. Switching to nfs-ganesha fixed the errors on my Linux client and seems to have made some of the errors go away on MacOS, esp the worst ones, like copying a file but it's 0 bytes afterwards.

ARM cluster running Glusterfs. #glusterfs #cluster #arm

So I've been doing some #storage management, moving around my #GlusterFS bricks. It's been surprisingly problem-free... including seamlessly dealing with open files on the bricks.

But one #ProTip: putting a replica and arbiter on the same physical host is fine, until said host decides to crash in the middle of the night.

🏷️ #SelfHosting #Selfhosted #Outage

I managed to do something awesome today with Vagrant, Ansible, Docker, Traefik, and GlusterFS. I constructed a docker swarm with persistent volumes. I deployed a sample stack (bookstack) and then "shutdown" one of the docker hosts with part of the stack on it. There was a brief lag in the application, but then it continued on its merry way as if nothing had happened!! #docker #vagrant #ansible #traefik #glusterfs

Up next in my series on how and what I #SelfHost: #Storage

I've talked about my #UnRaid server before, my VMs run on there. The built-in docker is added to my Docker Swarm, so it gets assigned containers from the swarm to run.

I also run a #GlusterFS cluster of 3 nodes across the two laptop SSDs (plus one arbiter VM). I run things like my Docker Registry backed onto Gluster, so the images are still available if any one node is down. Overall, I find Gluster slow, and its broken on me a couple times, but it does what I need it to do.

Ultimately, if a docker container requires storage, it will usually get Gluster (and the container run on the laptops), unless it has special IO requirements. Things like SQLite databases will corrupt themselves on Gluster or NFS. So I use deployment placement constraints to hold some docker workloads on my UnRaid server.

In the past, I ran containers anywhere, and they would volume-mount NFS or CIFS to UnRaid, but I ran into a "Stale File Handle" problem -- where containers would randomly have their volumes fail under them, and it would corrupt databases, leave processes stuck in IOWait, etc. No matter what I did, what protocol I used, etc, it would always eventually have problems.

I also run #GarageHQ S3 on my UnRaid server, though I haven't found a great use for it yet. I really want to run #WeedFS, as I like the design and architecture, but likewise haven't found a use case.

🏷️ #SelfHosting

Does anyone know the current story with #GlusterFS and #Kubernetes?

Heketi is in "deep maintenance mode" and gluster-kubernetes is archived.

But what's the alternative? There's Kadalu, but that's not "on GlusterFS" it's kind of it's own GlusterFS.

What are folks using out in the world?

Thanks! 🙂

Starting to look into network booting my #RaspberriPi with #glusterFS storage sharing. This is going to be interesting. I sure wish I could get 3 more PI4 4GB models.

What to do with 4 old #raspberrypi and some old laptop disks of varying sizes?
Installed @Manjaro minimal and set static IP for each board.
Disable non-essential services.
Add #lvm and disks to each using USB to SATA cable.
Install #glusterfs, probe all servers, create a distributed replica volume and start it.
Add #keepalived for a virtual IP.
Install gluster-client on main PC, and mount volume using VIP.
Result - fault tolerant NAS
All that remains is to build a case for it and upgrade disks.

Estimados! Les comparto algunas notas y pruebas realizadas con el sistema de archivos distribuido #glusterfs sobre sistemas #gnu #linux... va muy bien, sencillo de configurar y muy adaptable!

Espero les guste y les resulte interesante!

Acá ando, escribiendo un artículo sobre cómo montar un sistema de archivos distribuido #glusterfs en #GNU #Linux ... pronto novedades en el blog de @juncotic :)

Hoy dicté mi 2º clase en maestría! -> Admin #GNU #Linux, gestión de procesos, usuarios y privilegios, shell #scripting, conf de redes, #fstab, #raid, #lvm, #nfs, #samba, y #glusterfs, seguridad e #iptables... y todo con ejemplos en la cloud #openstack de la U. Muy intensivo? :P

Acá pasando el feriado preparando mi primer clase de posgrado (maestría): jugando con el sistema de archivos distribuido #glusterfs con servidores y cliente #ubuntu montados en una cloud privada #OpenStack... habrá que escribir un artículo sobre esto en el blog de @juncotic :D

This week @opensuse Tumbleweed had three snapshots. The major version update of #glusterfs moved from version 7.1 to 9.1 🥳 https://news.opensuse.org/2021/05/14/mesa-kde-glusterfs-update-in-tw/

Hi #all
I need your knowledge. I'm searching a @Linux #PAM #authentication method against a local #distributed #blockchain. My goal is to enable all users to login at every workstation in my network without central Server. The blockchain part is needed for consistent passwd changes and locking out old users. The home will be shared via #glusterfs later in the project. @bsi @lughannover @Linuxkumpel @linuxtechmore
