Re: [OmniOS-discuss] bug in powertop

[Zach Malone]

I gave this a go on 151012 (014 isn't available as an AMI yet, and I
can't get the 006 AMI to accept a ssh key pair on instance creation),
and saw the same thing.  powertop appears to segfault in
string_to_decimal / libc.so.1.

I then tried rebuilding powertop from the OmniTI illumos-gate build
scripts, but found that omnios-build:build/illumos/build.sh is a
little fussy for the uninitiated.

This sounds like a libc or kernel change, but I can't imagine why it
would show up on both 012 and 014.  Maybe someone with a working build
environment can dig further?

Re: [OmniOS-discuss] kvm networking

[graham]

Quoting "Dominik Hassler" :

you need a dedicated vnic for the kvm. I assume you have one vnic  
and use that one for the zone so it is not exclusive for the kvm  
guest anymore and won't work to my knowledge. You can always bind  
VNC to a unix socket so you don't acutally need a vnic for the zone  
(except that one which is used by the zone but most not be  
configured within the zone at all).


I found that if the vnic has an address for the zone, vnc works but  
the network access from the guest is sporadic at best. I tried with no  
address on the vnic, which means vnc doesn't work - but in my case  
that's not a problem as it's for an email server - and yes, outgoing  
connections work great, so it is probably how it should be. I can't  
talk to the email server from outside the zone, though. I don't know  
how I can pass the vnic to the zone without it being 'aware', unless  
you can add it as a device instead of a network interface?


Did you have a look at https://github.com/hadfl/kvmadm ? It'll do  
all the necessary setup for you for running kvms within zones.


I'll have to take a look at that, thanks.

With 151014, you don't need to explicitly add /dev/kvm and /dev/dld

[OmniOS-discuss] kvm networking

[Graham Stephens]

This must have been done millions of times already, but as a newbie I'm 
having great difficulty getting a kvm guest inside a zone to network 
properly. It seems to me that I've tried every combination of configs I 
can think of (except one, no doubt ;) ) but can't get anything outside 
the zone to talk to the guest, with the exception of vnc and ssh (which 
I presume must be built into the kvm mechanism?).


To the best of my knowledge (which isn't that much in this case), I've 
tried "-net user", "-net tap", "-redir", "hostfwd" in addition to the 
"-net nic" as shown on the wiki.
Linux help pages suggest it should be done by bridging, but 
"create-bridge" won't let me use the visible vnic as a link.


After two days of head-scratching I've decided I need assistance; if 
anyone can please point me at a working methodology I'd appreciate it. 
Be warned though I might need it spelling out :)

Re: [OmniOS-discuss] Zpool export while resilvering?

[Schweiss, Chip]

I went through this problem a while back.  There are some gotchas in
getting them back online and firmware upgraded.   The is will not talk to
the drive until it has its firmware upgraded or cleared from the fault
database.

This drives will not flash with multipath enabled either.

I ended up clearing the fault manager's database, disabling it and
disconnecting half the SAS cables to get them flashed.

In general, yes this is a very good post. However, for more recent ZFS and 
certainly
the lastest OmniOS something-14 release, the write throttle has been completely
rewritten, positively impacting resilvers. And, with that rewrite, there is a 
few more
tunables at your disposal, while the old ones fade to the bucket of bad 
memories :-)

In most cases, resilver is capped by the time to write to the resilvering 
device.
You can see this in iostat "-x" as the device that is 100% busy with write 
workload.
That said, for this specific case, the drives are not actually failed, just 
taken offline,
so you could have a short resilver session, once they are brought back online.

You might also crank up the priority on your resilver, particularly if it

yes.

yep, this is the broken 003 firmware from Seagate, know it well :-P

fwflash might work, but it is unlikely Seagate knows anything about it. In any 
case,
firmware upgrades on production system is not a best practice.

You can also disable the FMA agent, disk-transport, which is the agent 
responsible 
for watching to ensure the temperature does not exceed the "temperature at which
the drive vendor says the drive should not be operated" The impact to you is 
that 
the same agent detects other failures, such as predicted failures, that 
probably do
need to be noticed. For a short window, this option might work for you.

Useful commands:
fmstat - shows the current FMA modules, and should include 
disk-transport
fmadm unload disk-transport
fmadm load disk-transport

The temp checks (and PFA) are done once per hour, by default.

Not an answer to your question, but the approach I'd take is renting a
portable 110V or 220V A/C unit from somebody like spot-coolers.com to get
you through the resilver, then apply the firmware update. (And then I'd
start trying to convince management that it's worth adding a unit
permanently -- our Office Pro 24 24000BTU/hr cost us under $4k back in
2011.)

[OmniOS-discuss] bug in powertop

[Michael Rasmussen]

Hi all,

Anybody able to start powertop using some of the available options?
root@nas:/root# powertop -d 1  
Segmentation Fault (core dumped)
root@nas:/root# powertop -t 10
Segmentation Fault (core dumped)
root@nas:/root# powertop -d 1 -v
Segmentation Fault (core dumped)
root@nas:/root# powertop -c 0   
Segmentation Fault (core dumped)

The only way I am able to start powertop is using defaults.

[OmniOS-discuss] Zpool export while resilvering?

[Robert A. Brock]

List,

This is probably a silly question, but I've honestly never tried this and don't 
have a test machine handy at the moment - can a pool be safely exported and 
re-imported later if it is currently resilvering?

In the way of a bit of background, I have a pool made up with thirty or so 4TB 
Seagate disks with a firmware issue that results in their max temp being set at 
40C as opposed to 60C. This particular pool is in an office building in Texas, 
in an air-conditioned server room. The condenser for this unit is in the 
building's plenum and when the building a/c goes off over weekends in the 
summer my server room a/c struggles and temps run up to about 85F or so. This 
is causing my pool to drop random disks lately (fmadm reports high temp and 
they get marked as removed from the pool), and I've only just narrowed it down 
to this firmware issue. Seagate firmware update utility is apparently Windows 
only, so the disks must come out for the firmware update, but the pool is 
resilvering several disks with days remaining, hence my original query.

Regards,
Rob
