Options for sharing accumulated VPS storage space as a single volume?
One way or another I ended up with a very reasonable (quite sure it's still single digits) number of VPN's. Most of them got more storage space than needed, but a couple could use some more space.
Is there a 'best' way to create some JBOD-like storage on one of my VPS out of left over bits of other VPS's?
I love SSHFS and use it to bolt all kinds of things together. It gives separate directories for each mount point, so with 5 VPS's that have 2 GB left, I can create 5 separate directories on the 6th server. Is there a way to homogenize those into a single 10 GB directory or volume?
I hardly have any experience with NFS or iSCSI, I think those won't be happy with the relatively high latency between hosts. Would an open source S3 storage framework work? Would Ceph or Gluster give what I look for?
The storage is mostly needed for Nextcloud. It doesn't need to be very fast. All VPS's run Debian.
