example alignment issue

In FreeBSD-12.2R the "zpool list -v" alignment is weird. It seems to align each pool individually, but not across pools. The output was aligned more correctly with FreeBSD-12.1.

Example output attached.

Issue still present in freebsd 13.0-RELEASE.
Comment 2 Yuri Pankov freebsd_committer freebsd_triage 2021-04-13 22:37:52 UTC 
Can you provide the output from 13.0-RELEASE?  I have noticed only the following issue with per-vdev health: https://github.com/openzfs/zfs/pull/11899.

Yuri, it does at first look indeed seem like the issue is now limited to per-vdev health, whereas before it was much much worse. Great news indeed!

Output from a system with FreeBSD-13.0:

NAME        SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
zbuild      464G   137G   327G        -         -     5%    29%  1.00x    ONLINE  -

zroot       228G  3.73G   224G        -         -     2%     1%  1.00x    ONLINE  -

I do have a different system with two pools with vdevs with very different lengths, which I haven't yet upgraded. Here is an example of the FreeBSD 12.2 output from that system for a comparison:

Finally got around to upgrading the freebsd 12.2 system with many vdevs with a variety of name lengths, to freebsd 13.0.

Confirmed that only the health column is misaligned now. Great!
Comment 5 Yuri Pankov freebsd_committer freebsd_triage 2021-04-16 23:38:54 UTC 
The PR I mentioned above is merged in openzfs, though I am not sure if/when it will be merged to stable/13.
Comment 6 Mark Linimon freebsd_committer freebsd_triage 2025-10-30 14:59:16 UTC 
^Triage: is this still a problem on supported versions of FreeBSD?
Comment 7 elij 2026-05-05 22:37:22 UTC 
No, this has been fixed (using FreeBSD 15).
