September 26, 20214 yr So far I've figured out that /boot is the USB flash drive so changes to files on it are persistent. It looks like all of the other ones are dynamic so changes to files are lost. Are there any others that are persistant?
September 26, 20214 yr Off the top of my head for a stock install, the flash drive on /boot, array disks in /mnt/disk(X), named pools in /mnt, docker image in /var/lib/docker, VM image in /etc/libvirt. Pretty much anything else is user added, like /mnt/disks/* and /mnt/remotes/* for Unassigned devices. Use the df command to see what all is available. Since /boot is FAT, there are restrictions because FAT doesn't honor all permissions. The mount points are available at different times based on what is started and what isn't, so if you need access without the array started you are limited.
