Hello stable.
I've tried to make two journaled partitions on new GPT disk.
Partitions have GPT labels storage and backup:
gpart show -l ada1
=> 34 2930277101 ada1 GPT (1.4T)
34 8388608 1 (null) (4.0G)
8388642 2415919104 2 storage (1.1T)
2424307746 8388608 3 (null) (4.0G)
2432696354 497580781 4 backup (237G)
gjournal label /dev/gpt/storage /dev/gptid/3570dff6-9a73-11e0-ad0e-001e8c0ecc19
gjournal label /dev/gpt/backup /dev/gptid/58db2577-9a73-11e0-ad0e-001e8c0ecc19
newfs -J /dev/gpt/storage.journal
newfs -J /dev/gpt/backup.journal
Where 3570dff6-9a73-11e0-ad0e-001e8c0ecc19 is GPT UUID of ada1p1 and
58db2577-9a73-11e0-ad0e-001e8c0ecc19 is GPT UUID of ada1p3 partition.
This partitions have been added to fstab:
/dev/gpt/storage.journal /mnt/storage ufs async,rw 0 0
/dev/gpt/backup.journal /mnt/backup ufs async,rw 0 0
After reboot system doesn't wanna see gpt-labeled partitions
/dev/gpt/storage.journal and /dev/gpt/backup.journal (so, mount fails)
but has /dev/ada1p2.journal and /dev/ada1p4.journal instead.
How can I mount this partitions using GPT labels?

(amarat@ksu.ru already suggested an alternative that I believe works, but I thought I'd share my experience with this issue.) I ran into a similar problem with gmirror yesterday, but first my attempt at explaining why the above is happening. A geom(4) class "tastes" providers (e.g. ada1p2) in a certain order. When gjournal is tasting, it finds ada1p2 before gpt/storage, and creates ada1p2.journal. ada1p2 is then used, and gpt/storage is automatically removed. (Or alternatively, gjournal tastes before glabel, and there are no gpt/... labels when gjournal tastes providers; same result, though.) So to have the above work, glabel has to taste before gjournal, and gjournal has to taste the label device (gpt/xxx) before the real device (ada1p2). An alternative solution would be if gjournal creates a label itself, instead of adding ".journal" to the device name, for example /dev/journal/foo in the same way as gmirror creates /dev/mirror/foo. Then the journal device becomes independent of the device holding the data component, making it possible to mount /dev/journal/foo. Now back to gmirror. When I tried: gmirror label m1 /dev/gptid/xxx /dev/gptid/yyy it still showed up as using the actual devices. When I tried to hardcode the provider names: gmirror label -h m1 /dev/gptid/xxx /dev/gptid/yyy it said it labelled both /dev/gptid/... but the mirror failed to appear. But this does not matter for gmirror, since a device-independent mirror name is created in /dev/mirror regardless of the names of the components. The tasting order seems to be very important. Would it be possible to fix the above by changing so that labels are tasted before the "real" devices? Or does that create different problems? gjournal would perhaps find both gpt/xxx and ada1p2, resulting in a mess? I think the idea with labels is great, but whether it works or not seems pretty random to me as a user. (People with more geom knowledge than me, please correct all errors in the above :-) Perhaps labels are not tasted at all, like "real" providers are???) Bengt
