  1. [SOLVED] TRIM SSDs

    I have read all posts marked with trim but am still a little confused. Currently I have two PE nodes. Both have PE installed to an SSD. One has two further SSDs for VM disk images (using LVM-thin, discard always on); the other has HDDs which are passed through directly to the respective VMs...
  2. [SOLVED] How does email work?

    As above really - email is working great, but I just don't understand how. As far as I can remember I didn't put in any SMTP settings during the Proxmox install... and I see no relevant config in postfix. Googling suggests that the Proxmox ISO install "makes it work out of the box" so I'm...
  3. Scheduling SMART email alerts

    On Proxmox 5, I appear to already be able to see SMART data via the webgui. Further I can send email from the CLI: echo "testing" | mail -s "test" me@privacy.net So I suspect that email smart alerts are already working. My question is if there's a way to test it? Or perhaps get a monthly SMART...
  4. [SOLVED] Presenting a CIFS share to a Container

    I have mounted a CIFs share in my proxmox host that presents files as owned by foo:users. Foo's id is 1002. I want to present this share to a unprivileged container, I'm assuming using a bind mount. The user in the container has id 1000:1000, and creates files like so. I have added the...

  6. Unprivileged Bind Mounts and multiple access

    Say I have 5 containers each running an application. For each I have bind mounted a directory: /mnt/container_data/container1 /mnt/container_data/container2 etc Where the application will contain all its application data. I now create a further container running a backup application. To that...
  7. Disadvantages of non-HA cluster?

    I have two nodes running at home. They each use local storage for images (backup, HA or fast migration aren't really necessary here), with each guests "manually" accessing a NAS for non transient data. I'm looking at running the two nodes in a cluster, if only to manage them from a single web...
  8. [SOLVED] Default file system?

    According to the documentation I've read and searched for, ext3 is supposedly the default filesystem for proxmox installations. However on installing 4.4-1, it seems that it actually uses ext4. Filesystem Type 1K-blocks Used Available Use% Mounted on udev devtmpfs 10240...
