vnet jail crash
Hi,
After updating to 12-STABLE I am getting kernel panics when re-starting the
jail service. Here's a backtrace:

devd rule wierd output
Hi,
I have this in my devd rules:
notify 10 {
match "system" "ZFS";
match "type""misc.fs.zfs.scrub_start";
action "touch /var/run/scrub_$pool_name; logger -t ZFS 'zpool $pool_name
started scrubbing'";
};
While this is working OK on FreeBSD-10, on FreeBSD-12 I noticed that
$pool_name is different. FreeBSD-10:
Sep 5 20:35:56 clio ZFS: zpool clio started scrubbing
FreeBSD-12:
Sep 5 20:47:35 aurora ZFS[1302]: zpool $aurora-os started scrubbing
While it assigns the value, it weirdly includes a dollar sign
at the front.
Thoughts?
Should I open a PR?

On 05/16/2017 05:08 PM, Fabian Keil wrote: Why did you use the -f flag? Unless you can reproduce the problem without it, it's not obvious to me that this is a bug. If you boot from another system, there is no other way to import a pool than using "import -f". So, I guess it is part of normal administrative tasks. You can read more here: http://docs.oracle.com/cd/E19253-01/819-5461/gazuf/index.html This works and always have worked as documented. Renaming a pool also works as documented, that is, doing "zpool import oldnamepool newnamepool". Except for this corner-case. IMHO this is a very serious bug.

This will provide redundancy between different ethernet switches, I just don't know if RSTP converges fast enough for your needs. Just be a bit careful selecting the bridge's priority. A priority of 61440 will be probably fine. I am *almost* sure, that if_bridge works over if_laggs, perhaps you could combine the two.

I tried doing the remounting trick, both for root and /usr, back in the 4.x time frame. And could never get it to work - would always end up with inconsistent file systems. There were many fixes in this area lately. The case where a file system with softdeps would fail to update to read-only is fixed in -CURRENT and these changes are merged to -STABLE. It is believed to work correctly. http://lists.freebsd.org/pipermail/freebsd-stable/2008-October/046001.html Remounting with soft updates enabled used to be too fragile to be useful.

(Assuming you have the debugger in your kernel?). Yes, I have included my kernel configuration, see bellow. Does it still ping? no, ARP does not work as well. nasty.. do you have IPMI? sometimes that allows you to generate an NMI that could theoretically be made to drop to the debugger. I have a Dell PowerEdge 750 sitting at work, which I think has IPMI. I'll be able to try a few things next week, since I will be off work for this week. I've not had success with that but I have heard others have. An increase number of server motherboards have an NMI button on the motherboard, possibly exposed outside the case, but generally not. I've not tested it in over a year, but a few years ago I added an MP_WATCHDOG kernel option that causes one of the CPUs in an SMP system to become a dedicated watchdog CPU, checking to see if the OS is alive enough to process timer tickets. If a counter isn't updated, it generates an NMI to the debugger from the watchdog CPU. The idea here is that, as the number of CPUs increases, the cost of dedicating a CPU for debugging stuff gets lower. However, there have been quite a few scheduler changes in the last few years, and it's possible that the watchdog no longer properly excludes other work from being scheduled, and that further work is required. In particular, I believe it relies on 4BSD's pull scheduling model and a lack of per-CPU workers, so the mechanism may require some rethinking. Unfortunately, I have not an SMP system available. Is there a mechanism which I can use to schedule a break to the debugger after n seconds or events? I am looking if ichwd(4) can help, though that needs investigation since I have not used watchdog facilities before.
