I have a number of machines in Azure, all booting from ZFS and, until
the weekend, running 10.3 perfectly happily.
I started upgrading these to 11. The first went fine, the second would
not boot. Looking at the boot diagnistics it is having problems finding the
root pool to mount. I see this is the diagnostic output:
storvsc0: <Hyper-V IDE Storage Interface> on vmbus0
Solaris: NOTICE: Cannot find the pool label for 'rpool'
Mounting from zfs:rpool/ROOT/default failed with error 5.
Root mount waiting for: storvsc
(probe0:blkvsc0:0:storvsc1: 0:<Hyper-V IDE Storage Interface>0): on
vmbus0
storvsc scsi_status = 2
(da0:blkvsc0:0:0:0): UNMAPPED
(probe1:blkvsc1:0:1:0): storvsc scsi_status = 2
hvheartbeat0: <Hyper-V Heartbeat> on vmbus0
da0 at blkvsc0 bus 0 scbus2 target 0 lun 0
As you can see, the drive da0 only appears after it has tried, and failed,
to mount the root pool.
Normally I would just stick in a big 'vfs.mountroot.timeout' but that
variable doesnt not appear to exist under 11 - or at least it doesnt
show up in sysctl.
I have one machine which boots fine. I can take the drive of this machine,
clone it, and attach to a new VM, and that VM fails to boot! Am now
a bit scared to reboot that virtual machine in case it doesnt come back.
Can anyone offer any suggestions ? Just being able to delay the
mount might be enough if there is a variable which can do that. I do
rather need to get these machines back online....
thanks,
-pete.
