if i boot into single user mode, and attempt to import a zfs storage pool that is part of the normal system, i get "cannot import 'zstore': pool was previously in use from another system." ... is that expected? it suggests -f to import

(this pool has never been part of another system)

Is hostname set at that point in single user mode?

I have only ever encountered that question prompt when I have actually been importing an array onto a different system.

( And also I am running root on zfs so I can't get to single user mode without having already had the array imported. )

rwp: hostname is not set, so maybe that's it? it's not clear what it references.

In single user mode try setting the hostname before trying the import. That's a guess on my part.

no luck. there's a bit about "Last accessed by (hostid=57e453c6)"

i'd suspect it's using hostuuid -- yeah

most likely smbios isn't supplying the hostid for this system, it was generated and we rely on the hostid rc script to set it from what's recorded in userland

is there a way to trigger it so that it matches, or should i just ignore it and -f on the import?

TIL that there is a hostid and a hostuuid. Try this: sysctl kern.hostuuid kern.hostid

hostid is 0, hostuuid is populated by no part matches what zfs import reports

*but no part

Maybe run /etc/rc.d/hostid to set it? I am learning this all today for the first time myself.

It seems that systems might have a hardware uuid: kenv -q smbios.system.uuid

But the system saves the uuid it is using: cat /etc/hostid

That did it. "/etc/rc.d/hostid start" populated hostid and now they match.

import worked with no complaints

Good deal!

Notice I have avoided making any query about what needed to be done in single user mode that also needed to have an auxiliary data array mounted. :-)

thanks for the help!

if you're curious, i've got a bulk storage zfs device and planning to change some things up with how i'm setup and thought it wise to do it in single user mode

I was curious. Thanks! :-)

So i have a jail and "service pf status" says it is enabled inside jail, but there is no /etc/pf.conf on the jail ... the host has /etc/pf.conf and pf enabled. When i run "service pf onestop" in the jail, it stops pf in the jail and in the host also. Why is this ? Is it a misconfiguration that i have ?
