Color me THROUGHLY perplexed! Got a rockstor tarball/build I can lay down on top of this working setup or can I safely assume it is a BIT more complicated/complex than that?
@whitey Well look at you go, this is great. And are you game to try the elrepo kernel?
On a Rockstor 3.8-10.03 we have:-
uname -a
Linux rockstord 4.2.5-1.el7.elrepo.x86_64 #1 SMP Tue Oct 27 12:32:38 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux
I’m afraid the tarball / build question is more one for @suman, but you will need the elrepo kernel anyway really as 3.10 is ages old for btrfs.
Anytime now someone will get fed up with all this and jump in with a nice obvious point that we both missed, here’s hoping.
What, you guys already have a .03 update release out for 3.8-10 or is that internal? 
I am certainly game/down to try whatever out, long as we think/feel it has ‘legs’. This is all test/boom boom env stuff for me, can spin/up and tear down in a matter of mins. I just don’t wanna bother anyone if the ‘bang is not worth the buck’ as in if we think it is specific to me/my env (I don’t think it is/can be but hey I’ll keep an open mind) then let’s scrap it but if we feel there may be a ‘red headed gremlin’ running rampant that ‘may’ bite anyone else let’s press on.
What’s the easiest way to implement elrepo kernel? Do I need to uninstall/blacklist or just move kernel boot order in grub.conf/menu.lst?
May need a lil hand holding but not much.
One of these days we’ll put this one to bed!
I think it’s certainly worth the effort and prudent to install the elrepo kernel at least, given it’s so key to btrfs and our little investigation.
My understanding re elrepo kernel install is add the repo and install as usual:-
Instructions are available at http://elrepo.org/tiki/tiki-index.php
I know that’s a rtm type answer but other than that I don’t really know.
But you will want their ml (main line) variant, currently we have:-
yum list installed | grep kernel
kernel-ml.x86_64 4.2.5-1.el7.elrepo @anaconda/3
OK just had a look and I see a problem here, they appear to only now have 4.3.2-1 and 4.3.3-1 so we can’t directly compare, which is a shame.
@suman how do we install the exact same kernel as Rockstor carries.
As for 3.8-10.03 its a minor fix up from what you have already tried in the testing channel.

@whitey Yet more good findings I would say. There is the matter that the kernel on Rockstor didn’t change between 3.8-10 (working) and it’s .02 (not working for you) update but a whole lot of other stuff did via the CentOS updates and maybe the system was unable to present those disks with the driver in that state after the updates when before them it muddled through and did present them.
I definitely think you are onto something and it’s great to see those drives showing up. So this looks like some kind of regression that was aggravated by the 4.2.5-1 ml elrepo kernel in Rockstor that isn’t suffered by the 4.3.3 elrepo kernel, or the default CentOS kernel for that matter, which is great news. Of course we would need to install the 4.2.5-1 in the vanilla CentOS 7.2 to know but I’m fairly sure that there are plans to upgrade the default kernel in Rockstor anyway soon so this may all fall into place. Given that the btrfs-progs and kernel are best kept in step maybe the next thing to try is installing this newer elrepo kernel in an updated Rockstor 3.8-10.03 and see if it sorts things. But as I say the btrfs-progs are best kept in line with the kernel version however these have recently been updated in Rockstor so probably new enough for this test (non production for now).
yum list installed | grep btrfs
btrfs-progs.x86_64 4.3.1-0.rockstor @Rockstor-Testing
I suspect we are waiting on elrepo releasing a 4.4 kernel, not sure. I think @suman is currently pretty deep into the rock-on docker stuff at the moment so the kernel upgrade may be taking a back seat.
To my knowledge (which is very limited I might add) Rockstor uses a completely unaltered elrepo kernel, there just isn’t the people power for us to role a custom one. Although @Dragon2611 in the forums has been compiling his own, and making it available for people to try.
Note that change the default kernel expected by Rockstor so that you don’t get the warning message etc see another post and it’s answer from @Dragon2611 again :-
http://forum.rockstor.com/t/override-kernel-autoboot/798
The difference re 32 & 64 bit is strange / interplay with motherboard pci drivers maybe. You could look at available module options eg:-
modinfo mpt2sas

Building kernel on rockstor is actually pretty easy, off the top of my head I believe it’s as follows
install the development tools packages
yum group install “Development Tools”
Install gzip if it’s not install (Yum install gzip)
cd to /usr/src
grab the kernel sources from kernel.org
extract the file
symlink link the extracted dir to /usr/src/linux (I don’t think this is actually required but it’s slightly neater)
enter the directory
make clean
cp /boot/config-4.2.2-1.el7.elrepo.x86_64 .config (Note replace the 4.22 with the current kernel version tab should list the available options)
make menu config
8a) press load and load the .config file (should be the default)
8b) make any changes needed to compile any extra drivers you need, if you are careful you can also disable stuff you don’t need, I take the approach if I don’t know what something does I leave it on whatever it was set to before.
8c) press save then exit
9a) go get a cup of coffee and find something to do for a while depending on the speed of your rockstor box this could take anything from 15minutes to several hours.
if all worked you should be able to find a load of RPMs in /root for the kernel, headers.etc
install with your favourite package manger.
The only gottya I did run into is Yum may not auto remove custom kernels when you upgrade to a newer one so after a while you will have to delete some older ones or /boot will get full and you won’t be able to install any more.
@Dragon2611 Thanks, this is a great post. I didn’t realise the rpm could be made so easily. Is make oldconfig still an option these days as if so it may well stream line the process a little, especially if one is just going with the defaults?
I’ve not actually tried,
Also one thing I did change between the ELREPO and my kernel was to compile BTRFS directly into the kernel rather than rely on loading it as a module, I figured given how extensively rockstor uses it that it didn’t seem like a bad idea.
Cute another reboot and now I see this garbage on the CentOS 7.2 (1511) box I upgraded to kernel 4.3.3)

If I reboot back into kernel 3.10 on the CentOS 7.2 (1511) tester box then it works.

Crazy thing is I KNOW I rebooted into the 4.3.3 kernel and had it working at some point late last night…SMH
Guess I DO have FW v19 on the HBA, looks like CentOS 7.2 is loading driver v20. I know FreeNAS moved to driver 20 and firmware 20 otherwise the GUI complains. I could start there I suppose. I have a couple spare 9201-8i in IT v19 mode, will flash up to v20 and attach the stg appliance VM in vt-D mode adn see what happens.
Even in kernel 3.10 I have same mpt2sas driver so I may be chasing a ghost.

I think this card is a Dell Perc H310 which is essentially a re-branded LSI 9211-8i (all sas 2008 HBA’s), but all I reflash to LSI official IT mode firmware version 19. Maybe it’s time to move to version 20 of firmware as time/drivers/distro’s march on, v19’s been rock solid for me for at least the last 4-5 years though it seems.
Anyone else running a similar setup here? Essentially an AIO (all-in-one) build w/ a hypervisor and vt-d pass thru stg ctrls to the VM driving the array/nas?
EDIT: Manually setup raid10 btrfs pool across those 4 hussl sas ssd’s and configured NFS (still booted back into 3.10 kernel as the 4.3.3 kernel sh|t the bed apparently or had that one flukie ‘Hey I see devices’ complex’, now nothing), mounted to vSphere/ESXi hosts, crushing 350MB/s in/write and 300MB/s out/read to another ZFS NFS backed pool and my vSAN AFA floating a few VM’s around using sVMotion.
mkfs.btrfs -m raid10 -d raid10 /dev/sdb /dev/sdc /dev/sdd /dev/sde
You guys are gonna force me to become a btrfs cli junkie yet! But I LOVE the dashboard!
KNEW I wasnt losing my damn mind, now w/ 4.3.3 booted it AGAIN see’s disks…inconsistent to say the least. Just flashed up a spare LSI 2008 6Gbps HBA/ctrl to firmware v20. Gonna see if that helps.
Have NOT given up yet!
Flash of a LSI 6Gbps HBA to v20 didnt seem to help much, still very inconsistent drive identification/sensing. My CentOS box DOES currently see the disks w/ 4.3.3 kernel, I tried to unblacklist util-linux goodies and apply a yum update -y and it re-upgraded the 4-5 util-linux and deps, even updated to RS 3.8-10.03. NO GO
Tried to lay down a 4.3.3 kernel on RS and boot into that, akin to what I did on my CentOS 7.2 build w/ 3.10 kernel to take it to 4.3.3. NO GO (move from RS 4.2.5 kernel to ELREPO 4.3.3).
I stink.
@whitey I have exactly the same problem. I’m using a Dell H310 with P20 IT firmware with vt-d passthrough in ESXi to linux. Any time I try something with kernel 4.2 or newer, I have the same timeout after 30 seconds.

The only reliable way I’ve found to make it work in 4.2 is to boot into something older like 4.1 first and then reboot back into 4.2. Every time I do that it works.

Pounding some sVMotions into a r10 from vSphere infra. 25K iops consistent!
Probably not the right place for it but it sure would be nice on the Disk activity chart to have another ‘view’ of I/O latency/response time right there in the same dashboard as well as your already provided IOPS across the pool/disks view. I know it can get crowded on a dashboard and you don’t want it to look ‘too busy/scattered’ but maybe something to consider.
I also DID recently do a lab upgrade/refresh from an E3 to E5 platform across my 3-node vSphere cluster but I doubt that had a thing to do w/ it. More resources sure are nice though (double cores/quadruple memory)
The saga continues for me, I stepped away from this for a bit once i realized I rebooted and issues popped up again. I have now been able to re-produce exactly what happens. After initial install/first boot i can see disks and mpt2sas driver/msg in dmesg look happy. If I simply reboot i can then no longer see disks and mpt2sas looks unhappy again.
See images. SMH
Drum roll…wait for it…and the fix for me was:
mpt2sas.msix_disable=1 (for 4.3 or older kernels)
or
mpt3sas.msix_disable=1 (for 4.4 or newer kernels)
Added to kernel boot line parameters, adding here as well for prosperity’s sake.
Under ubuntu or CentOS using grub2 to make it stick edit the /etc/default/grub to the following:
GRUB_CMDLINE_LINUX_DEFAULT=“mpt2sas.msix_disable=1”
(mpt3sas.msix_disable=1 for 4.4 or newer kernels)
Save file:
Then update grub2 files:
Ubuntu - update-grub
CentOS - grub2-mkconfig -o /boot/grub2/grub.cfg (BIOS based machines)
grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg (UEFI based machines)
