MergerFS Migrate Pool to New System

  • Hi all,

    Union Filesystem Plugin: I have a MergerFS pool setup as follows:

    /dev/sde1                    1.9T  2.0G  1.9T   1% /srv/dev-disk-by-label-WD2TBTwo
    /dev/sdb1                    1.9T  2.0G  1.9T   1% /srv/dev-disk-by-label-WD2TBOne
    /dev/sdc1                    3.7T  1.3T  2.4T  36% /srv/dev-disk-by-label-SGT4TBTwo
    /dev/sda1                    3.7T  1.3T  2.4T  36% /srv/dev-disk-by-label-SGT4TBOne

    SDC1 is parity...the other 3 are inside a MergerFS pool. So I have a motherboard replacement that needs to take place...which means I'll have to reinstall OMV on the system drive. Since MergerFS spans data across drives, what's the proper way to take a pool that was on one system and get it up and running on the other system without losing data?

    Has anyone ever done this before? Am I over-complicating things?
