As you can see it updated the changes. BUT glabel didn't get informed about the changes:
FreeBSD [~]# glabel status
Name Status Components
gptid/2fed8e3d-f4f9-11e0-beaf-000fa30711f1 N/A ada0p1
gpt/RootFS N/A ada0p2
[...]
gpt/Storage N/A ada2p1
gptid/9e34e5b5-f747-11e0-b222-000fa30711f1 N/A ada2p1
[...]
As you can see it still has outdated label-information "Storage" instead of "New-Name"
FreeBSD [~]# ls -lach /dev/gpt/
total 1
dr-xr-xr-x 2 root wheel 512B 15 Okt 13:26 .
dr-xr-xr-x 11 root wheel 512B 15 Okt 15:26 ..
[...]
crw-r----- 1 root operator 0, 114 15 Okt 15:26 RootFS
crw-r----- 1 root operator 0, 173 15 Okt 18:06 Storage
[...]
BUT the funny thing is that glabel gets the changes ONLY AFTER I rebooted the machine.
glabel after reboot:
FreeBSD [~]# glabel status
Name Status Components
[...]
gpt/RootFS N/A ada0p2
gpt/New-Name N/A ada2p1
[...]
>Fix:
a simple restart would fix the problem
OR restart the device by i.e.:
FreeBSD [~]# true > /dev/ada2
Which in my opinion should be done auomatically after label change - as it was in previous RELEASE. Otherwhise what's the use of a framework if user still has to interact while expecting framework apps to communicate among each other.
