Failed GEOM mirror on 2.7.2 install

[RebusCom]

On a router that had 2.5.2 installed in a mirrored configuration, I performed a memstick install of 2.7.2, choosing the Auto ZFS install selecting mirror with the two SSD's selected. Install went fine but the GUI shows both drives healthy but no mirror. Both drives show under consumer information with the same sizes for each partition on each drive, but I see no way to reconstruct the mirror. Is this a reporting bug or a nonfunctional mirror?

Newer versions use ZFS Mirror instead of GEOM Mirror, if I understand correctly.
I think that if you also mirror Swap, then it uses GEOM mirror only for the Swap partition along with the ZFS Mirror

Use SSH or Diagnostics / Command Prompt and enter "zpool status", it should return something like below

NAME        STATE     READ WRITE CKSUM
pfSense     ONLINE       0     0     0
  mirror-0  ONLINE       0     0     0
    ada0p4  ONLINE       0     0     0
    ada1p4  ONLINE       0     0     0

Excatly that ^.

When you install as ZFS you select mirror at install and it creates a zpool mirrored on both drives. That is not a geom mirror so it's not shown as such there.

That is the case. I am not mirroring the Swap, btw. Thanks. So I guess the next step is to figure out if the status dashboard can be revised to display ZPOOL status. Any Widgets available or in the works?

There is a ZFS widget in Plus but it doesn't specifically show mirror status. There isn't yet a gui method to add/remove disks from the mirror.
