  • I just snapshot the parent lxc. The data itself isn’t part of the container at any level, so if I bung up compose yml or env, I can just flip it back. The only real benefit is that all my backups are in the same place in the same format.

    Like I’m not actually opposed to managing docker in one unit, I just haven’t got there yet and this has worked so far.

    If I were to move to a single platform for several docker, what would you suggest? For admin and backups?

    I use individual lxc for each docker compose so I don’t have to revert 8 services at once if I need to restore.

    I would also argue that an alpine lxc runs in 22mb ram by itself … Significantly smaller footprint on disk and in memory. But most importantly, lxc can actually share memory space effectively, one doesn’t need to reserve blocks of ram.





  • So I went to the demo and I have a few questions:

    • Couldn’t figure out how to use 3d in demo (not critical)
    • developer discord link on github is expired
    • distinction between “public” and “shared” trails isn’t clear
    • “Completion Status” for trails… what does this mean?
    • Couldn’t import a trail in demo:
    haystack-mountain-101522-105940.gpx
    {"message":"TypeError: Cannot read properties of null (reading 'id')"}
    

    I am actually really impressed with what you have so far, and I’d love to start using this!





  • Are you having trouble reading context?

    No, I’m not applying 2005 security, I’m saying NFS hasn’t evolved much since 2005, so throw it in a dedicated link by itself with no other traffic and call it a day.

    Yes, iscsi allows the use of mounted luns as datastores like any other, you just need to use the user space iscsi driver and tools so that iscsi-ls is available. Do not use the kernel driver and args. This is documented in many places.

    If you’re gonna make claims to strangers on the internet, make sure you know what you’re talking about first.





  • Your workload just won’t see much difference with any of them, so take your pick.

    NFS is old, but if you add security constraints, it works really well. If you want to tune for bandwidth, try iSCSI , bonus points if you get zfs-over-iSCSI working with tuned block size. This last one is blazing fast if you have zfs at each and you do Zfs snapshots.

    Beyond that, you’re getting into very tuned SAN things, which people build their careers on, its a real rabbit hole.
