2 node HA fail-over storage configuration possible using Rclone?

What is the problem you are having with rclone?

The problem is not directly related to rclone, but a proper setup of rclone might ofer the solution! Please allow me to elaborate shortly and ask if there is something I can do to make this work. Thank you in advance for any help!

What I'm trying to achieve: Gluster replication (or rsync or maybe a different bi-sync solution) between a local ZFS folder on Server1 and a Rclone-Pcloud VFS folder (the tested working command used for mounting is pasted below) on Server2. The end goal is to have some sort of HA storage with off-site fail-over. Is this feasible?

Problem: I didn't manage to mount the Rclone VFS folder into Gluster on Server2 (I even tried to mount --bind 2 separate folders, one for Rclone and one for Gluster and it almost worked!!! I can elaborate further about what I tried if it's useful), but I suspect it might be possible if I (would be smart enough to) configure rclone properly. If Gluster is not the way to go, what else could I try to achieve this 2 server HA solution?

Many thanks for any help!

Run the command 'rclone version' and share the full output of the command.

rclone v1.62.2

  • os/version: debian 11.7 (64 bit)
  • os/kernel: 5.15.107-2-pve (x86_64)
  • os/type: linux
  • os/arch: amd64
  • go/version: go1.20.2
  • go/linking: static
  • go/tags: none

Which cloud storage system are you using? (eg Google Drive)


The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone mount pcloud-crypt: /SSD-ZFS/rclone-pcloud/mount --config /root/.config/rclone/rclone.conf --vfs-cache-mode full --vfs-cache-max-size 500G --cache-dir /SSD-ZFS/rclone-pcloud/cache --allow-other

instead of DIY HA why not to use proven open source solution like ceph?

Is it possible to somehow "tie" Rclone to Ceph for off-site storage? If so, I'll certainly try this out!!

What I ideally want is to have a large local storage (current hardware: 4 HDDs in ZFS mirrored configuration totaling about 20Tb) on Server1 and remote Rclone storage (using about 500Gb VFS cache of a 1Tb SSD to 10Tb off-site storage) on a very small & light Server2, everything bisynced so that I could shutdown any node (for maintenance or reduced power consumption etc) and everything would continue to work flawlessly!

I will give Ceph a second look to see if such a configuration, or similar, is possible!
Thank you and please allow some follow-up questions if I won't know how to achieve this with Ceph.

Out of the box you can tie Ceph to any S3 cloud

On first glance, I should use at least 3 nodes... I assume there are ways to circumvent these requirements, but before I dive into this completely new territory, would you mind to sketch out a possible working Ceph scenario using the hardware I already have (Server1 with 4 identical HDDs, Server2 with 1Tb SSD for caching to online storage using rclone or something native to Ceph)?

You will find plenty of resources on Internet, e.g.:

Good opportunity to do some research and learning:)

Well, it seems to me that Ceph cannot do what is outlined in this thread. Furthermore, if I would properly implement it, it would mean a lot more new hardware to buy, route that I, sadly, cannot take. Anyway, thank you for your suggestion.

Is the problem highlighted in this thread, namely creating a Gluster brick out of a Rclone mount, related to this other thread regarding the lack of xattr: https://forum.rclone.org/t/questions-regarding-extended-attributes/10553? If so, are there any news in this regard? Will something like this be possible in the future using rclone or rather not?

Thanks for any help!
