Proxmox

Sometimes, servers can become unresponsive and you may be unable to connect to them, particularly when they are overloaded. For such cases, most Intel PCs include a watchdog timer in the event the computer gets stuck and needs to do a hard reboot. Proxmox, however, disables all hardware watchdog drivers and enables softdog by default. In this short post, we'll quickly enable and test the Intel TCO watchdog in Proxmox.

One cannot use swap files on BTRFS and ZFS mirrors (or any other RAID levels), they require separate partitions. For high-availability and to ensure a drive failure doesn't result in a system crash, we need to create mirrored partitions and create our swap partition on top of that.

According to the XMRig documentation, enabling hugepages results in a typical hash rate increase of 20-30% for most algorithms with an up-to-50% increase in hash rate for RandomX algorithms. However, to run XMRig in an unprivileged container, we must reserve the pages on the Proxmox host ahead of time.

Debian 12, on which Proxmox 8 is based, has the correct driver in the non-free repository. However, that driver doesn't support the CUDA Toolkit in the non-free repository so it must be installed via run file downloaded from NVIDIA's website. In this post we'll go over installing the NVIDIA Tesla Driver 470 and CUDA Toolkit 11.4.
