The problem is a geom design point. When you have multiple aliases that you can open, the others are removed from the filesystem view when one is opened. It looks like from the above that the mirror-0 was created with the diskid, so that's the device that zfs opens, leaving the ada2 devices removed.

No I really didn't use diskids for pool creation. Those diskids are too long to type. :) That's why I explicitly post about commands I used:

I understand that "some" aliases are hidden when other style of aliases were used but I never see ada0pX missing even if gpt labels are used.

Also partition p4 prepared for swap was not used by any name style / alias so I expect to see it there but it is not there. ANd the behavior is the exact opposite - when I now tried to create swap with diskids, /dev/gpt/ directory was instantly created a populated with gpt label aliases:

# gmirror label -F -h gmGswap0 /dev/diskid/DISK-Z3010G8Vp4 /dev/diskid/DISK-Z302YC90p4

# ll /dev/gpt/
total 0
crw-r-----  1 root  operator   0xf9 Nov 28 23:22 swapC90
crw-r-----  1 root  operator  0x115 Nov 28 23:22 swapG8V



This is normal example from another machine with similar setup:

# ls -1 /dev/ada*
/dev/ada0
/dev/ada0p1
/dev/ada0p2
/dev/ada0p3
/dev/ada1
/dev/ada1p1
/dev/ada1p2
/dev/ada1p3
/dev/ada2
/dev/ada2p2
/dev/ada3
/dev/ada3p2

# ls -1 /dev/gpt/
boot0
boot1
disk0tank0
disk1tank0
ssd0tank1
ssd1tank1
swap0
swap1

# zpool list -v

As you can see there are aliases in /dev/gpt/, there are partitions for /dev/adaX devices and the pools are made of gpt labels.
This is what I expect from the system in my first post.

I will try to disable disk_ident as suggested by Freddie Cash.
