vinum (root on vinum too) throw_rude_remark crash: endless loop

[Dmitry Morozovsky]

Dear colleagues,

experimenting with vinum stripes and mirrors, I'd stuck myself with the
following:

panic: throw_rude_remark: called without config lock

(from vinumconfig.c:throw_rude_remark:103)


The system before this panic has two 160G drives with two vinum partitions on
each (one for mirrored root and one for the rest with swap between); these were
ad0 and ad2.

For the experiments, I'd added ad1 and ad3 disks, created adXh there, added
drives via vinum config, and then 1+0 vinum drive; however, I *did* forgot
adding /dev/ad{1,3}h to /boot/loader.conf. After reboot I got the panic message
mentioned above.

Adding missed partitions at loader stage did not help.

So, I'm stuck a bit. Even when I unload kernel modules and tries to load kernel
thru synthetic ad0a I got:

ok unload
ok load kernel
/kernel text=0x10042f data=0x19704+0x16e28 syms=[0x4+0x1e870+0x4+0x23e87]
ok boot -s -a

mountroot> ufs:/dev/ad0s1a
Mounting root from ufs:/dev/vinum/r
no such device 'vinum'
setrootbyname failed
ffs_mountroot: can't find rootvp
Root mount failed: 6
panic: Root mount failed, startup aborted.

AS you can see

Any clues to revive a system? Kernel boot log follows.

Sincerely,
D.Marck                                     [DM5020, MCK-RIPE, DM3-RIPN]
