  2. Migration hooks

    Hello, I'm using quite a few hooks in proxmox to do some additional stuff. Are there any migration related hooks available (I could not find any in the documentation or the perl code but maybe I'm missing something) ? My own use case would be the following: - when an LXC migration starts, make...
  3. SoHo-Cluster - Tips and Knowledge appreciated

    I probably miss interpreted the replies, and I'm going to stop here as our discussion is really floating away from the initial question. If you feel that L2ARC is populated by write requests, I suggest you to read https://blogs.oracle.com/brendan/entry/test especially the end. For sure data...

  6. SoHo-Cluster - Tips and Knowledge appreciated

    Hi, well as I said it's a test cluster for now - running of-site on some rented servers. Two identical for the sheepdog part and third low end one. Like always "production ready" is a little bit personal, but I can only say that I had much more issues with DRBD9 than with sheepdog once it...
  7. SoHo-Cluster - Tips and Knowledge appreciated

    Hi, I've been using DRBD on a 2 node cluster, but given the recent changes (and having had some issues with the linbit repos not being really up-to-date with the latest pve kernel) I'm now evaluating sheepdog.
