proxmox on sdcard

[efeu]

Hi,
I want to try installing proxmox on sdcard. Because of the lesser lifetime of sdcards compared to HDDs or SSDs I want to make as less writes on it as possible, so I'm thinking of setting mountpoints of /var and /tmp to other disks. Any other directories which should be mounted somewhere else, or any suggestions on doing that?

Regards

I would suggest making /tmp a tmpfs and mounting /var on a "real" disk.

all of the other folders should rarely be written to, except for when installing upgrades.

Mount filesystem with "noatime/nodiratime", have plenty of RAM for i/o-buffers, avoid any small writes, etc.

But anyway, I do not recommend this. SD-cards are not designed for frequent r/w access, and Proxmox (better said Debian) was not designed having this (running from SD-card) in mind. ESXi is different: it just loads OS-image from "disk" (be it hd/ssd/usb/sd or whatever) and then runs fully from memory...
