Re: IPv6 VM
IPv6 fully operational - named/bind9 resolving all dns and works fine for IPv6 only hosts…. ipcloud.ws is IPv6 only to the external internet and works fine via www, ssh, smtp mail, etc as long as you are on another IPv6 capable host. Pretty nice. I am glad you brought this up. If you need a database I will stick one on there for you or choose your own. Now moving on to local dhcp serving up IPv6 only stuff - I like how you can delegate dhcp services amongst various dhcpd's in v6 very cool.

Oh also if you would like to relay smtp mail give me a shout right now it's restricted to the IPv6 64 blog that the machine manages - heck if you want an IPv6 address I could give you one and it SHOULD work anywhere you are connected as long as your IP can deal with IPv6 RB On Jan 27, 2012, at 10:45 AM, Steve Bertrand wrote: On 2012.01.26 23:12, Robert Boyer wrote: just an FYI - that VM that you logged into tonight now has verified access via IPv6 from anywhere, is serving up the /64 block to my local devices vi route adverts, has route6d running and appears to work locally (resolves IPv6 name servers from other local machines via dig) nginx is now listing and serving pages via IPv6, and should also work have a working IPv6 email server (not tested yet).

Re: How to destroy a zombie zpool
I agree if you move drives and a particular zfs has not seen them before - and
there is a zfs label at the end things can go pear shaped - however…
if you blast just the end of the drive it should be fine.

zfs is famous for fucking itself like this. the only totally safe way is to
dd the drive since nailing the label doesn't clear out stuff at the far end
of the filesystem that can really ruin your day. don't ask me how i know..
it will take a few hours dd'ing from /dev/zero to your devices but it is
well worth it when you do any major surgery on drives that had zfs at one
point and you want to use them over again with zfs

To deal with this kind of traffic you will most likely need to set up a mongo db cluster of more than a few instances… much better.

Re: freebsd server limits question
Sorry one more thought and a clarification…. I have found that it is best to run mongos with each app server instance most of the mongo interface libraries aren't intelligent about the way that they distribute requests to available mongos processes. mongos processes are also relatively lightweight and need no coordination or synchronization with each other - simplifies things a lot and makes any potential bugs/complexity with app server/mongo db connection logic just go away. It's pretty important when configuring shards to take on the write volume that you do your best to pre-allocate chunks and avoid chunk migrations during your traffic floods - not hard to do at all. There are also about a million different ways to deal with atomicity (if that is a word) and a very mongo specific way of ensuring writes actually made it to disk somewhere = from your brief description of the app in question it does not sound that it is too critical to ensure every single solitary piece of data persists no matter what as I am assuming most of it is irrelevant and becomes completely irrelevant after the show- or some time there after.

Re: named/bind problems....
okay, lets start from the beginning here... 1) Do you have your own IP address and IP address block that you are hosting DMS for or is it local only? 2) from talking with you last night I want to make sure you are aware of two things... A) resolv.conf is used for name resolution on EVERY system it tells ALL of the software to get name services from. We fixed this last night for one of your systems by pointing it at a name server that works (the one you had did not work) B) named provides name services (as well as forwarding to other dns services) and can be pointed to by resolv.conf on you local systems - if it is not working AND your local resolv.conf files are pointing there your name resolution will not work. C) you can get internet name services working temporarily by using some of the servers I have you 8.8.8.8 and 8.8.4.4 in all of your resolv.conf files - you don't need named to work for this. You can also use /etc/hosts for your couple of local name/address translations as a work around until you get named working again. 3) dig is your friend for debugging named - you can use dig @local-dns-address lookup-name to debug your named while still using external name servers in your resolv.conf and local naming in /etc/hosts until you ACTUALLY are sure your local named is working. 4) The only thing you really really need a local named for is if you have a real IP block that you are responsible for providing name services on the internet for - rarely the case and even if you do you can temporarily jamb the names you care about in another DNS server somewhere out there like zoneedit or free dns temporarily. Get your stuff working then debug your named. RB On Jan 19, 2011, at 6:55 PM, Gary Kline wrote: On Wed, Jan 19, 2011 at 06:11:23PM -0500, Robert Boyer wrote: Sorry to see you are still having issues.

Need some device help
am in the process of moving all of my NAS from open solaris to FreeBSD (I hope?) and have run into a few speed bumps along the way. Maybe I am doing something way way wrong but I cannot seem to find any info at all on some of my issues. I hope this is the right list to ask - if not please steer me in the right direction. I am not new to BSD's but then again I am not intimately familiar with a lot of the inner workings and things have change a bunch since my kernel hacking days of NET2 on a vax so this is probably just a parameter somewhere but I cannot seem to find it. Here goes... Question 1? I am trying to get FreeBSD running ZFS to work as both a server and a consumer of iSCSI targets and can't seem to attach to more than 8 devices. In fact it seems to break after a TOTAL of 8 SCSI devices on the client (initiator end) after attaching 8 SCSI devices da0 through da7 target discovery even stops working with this message when running ANY iscontrol commend on the initiator. ISCSISETSES: Device not configured I believe this is on the initiator end and has to do with the total number of attached scsi devices but am not completely sure - I am using the built in iscsi initiator and kernel module NOT open iscsi and istgt on the server. Any ideas? Is this on the server end somehow? Ps. There is absolutely no messages in any log server or client after the 8 device and iSCSI stops working the above message comes from the iscontrol command with the -v option. Question 2? In order to make device names persistent I am using glabel on raw non-partitioned devices to simulate solaris persistent device names. I also understand that I can use GPT disks and that glabel somehow integrates with the GUID? Is this the case or is using GPT a completely independent alternative to using glabel? In any case what is the best/most common practice to achieving the end result (reliably and dependably) in the FreeBSD world?

How can this be with the default config? 2)Is there an option to run nanobsd.sh without cleaning the obj directories?

SAS HBA card for freebsd?
I have been running FreeBSD for about a year and tracking the ZFS implementation for almost as long. I am reasonably happy with the current stable 8.1 ZFS configs that I have been running with a few TB of storage all managed with an integrated SATA controller on my test machine. I am about to invest a little bit of money in a production machine targeted for a bunch of cheapo storage attachment and plan to implement on FreeBSD / ZFS. I have searched around on this topic and most info seems to be a bit out of date or contradictory, so here is the question at the risk of being redundant. I need a SAS controller that has preferably 8 ports (two four channel) connections per card. I don't mind decent buying a RAID card but really really desire it to be configurable in HBA mode vs. RAID or JBOD with RAID signatures. There are plenty of HBA only cards that would be suitable but I can find none that seem to fit the bill in terms of FreeBSD. I have seen a couple of cheap RAID cards recommended but cannot seem to get a definitive answer of whether they are actually configurable as plain old disks (HBA mode) vs JBOD w/ RAID signature.

I have searched around on this topic and most info seems to be a bit out of date or contradictory, so here is the question at the risk of being redundant. I need a SAS controller that has preferably 8 ports (two four channel) connections per card. I don't mind decent buying a RAID card but really really desire it to be configurable in HBA mode vs. RAID or JBOD with RAID signatures. There are plenty of HBA only cards that would be suitable but I can find none that seem to fit the bill in terms of FreeBSD. I have seen a couple of cheap RAID cards recommended but cannot seem to get a definitive answer of whether they are actually configurable as plain old disks (HBA mode) vs JBOD w/ RAID signature. Anybody using a reasonably priced card that fits the bill?
