next in thread | raw e-mail | index | archive | help
Hello,
I just upgraded my RELENG_5 box to RELENG_6. This machine has two drives
mirrored using gvinum. Everything was working well under 5.x, but when I
booted to 6.x I noticed only one drive was receiving transactions. I see no
error messages in my logs. Running 'gvinum list' produces the following
strange output:
2 drives:
D rootback State: up /dev/ad6s1h A: 92721/152625 MB
(60%)
D rootmain State: up /dev/ad4s1h A: 152625/152625 MB
(100%)

S backups.p0.s0 State: up D: rootmain Size: 20 GB
S backups.p1.s0 State: up D: rootback Size: 20 GB
As you can see the plexes for drive rootmain show zero size and zero subdisks.
The subdisks for drive rootmain, however, do show up and claim to have space.
I don't know if it matters, but these disks were originally setup with vinum
prior to the creation of gvinum. That being said, they have been running
with gvinum quite well under 5.x for a while.
Anyone have any ideas on whats going on here? Any help would be greatly
appreciated.
Thanks.
