[sOLVED] - should have read the troubleshooting section of v6 wiki, had to remove the 'startState' from the /config/disk.cfg file.

I have 2 unraid servers, 1 running directly on hardware & the 2nd one running on ESXi v6. I upgraded the first server to unRAID v6.1.3 from v5.0.5 no problem but trying to do the same thing on my 2nd server & I can't start the array. In the webgui it says 'configuration valid' but when I press the start button it looks like it's doing something for a few seconds but then takes me back to the same screen without starting the array (& no errors). Any idea what's going on?

yeah, i "requested a quote" on the Hynix stuff and they came back with the following response: "I just checked in with my purchasing manager and unfortunately there is no ETA. You may be interested in W1333EB8GS, which is the same specs, but just made with a Samsung chip"

Would this memory work with the X9SCM? (since the other memory is hard to come by) http://www.superbiiz.com/detail.php?name=W1333EB8GS

A little off topic but i had a question regarding UPS's. I've been running an unRaid box for about 3 years without a UPS. it's crashed due to power outtages probably at least 2 dozen times and other than having to run a parity check it doesn't seem like there has been any serious issues. Given the upfront cost and and the cost to replace batteries (about every 4 years or so) do you think a UPS is a necessity? If so, why?

Is that a better option than just doing passthrough on the NIC?

I'm not running VMTools because i wasn't sure if i wanted to rely on them since they aren't officially supported in unRaid. What's are the benefits of installing them? Should I install them?

So everything seems to be running pretty good except: after streaming a blu-ray across the network from the virtualized unraid box i started getting the following errors in syslog and my network performance would tank: Feb 19 02:15:30 Tower02 kernel: swapper: page allocation failure: order:3, mode:0x4020 Feb 19 02:15:30 Tower02 kernel: Pid: 0, comm: swapper Not tainted 3.0.3-unRAID #7 (Errors) Feb 19 02:15:30 Tower02 kernel: Call Trace: (Errors) Feb 19 02:15:30 Tower02 kernel: [<c105f857>] warn_alloc_failed+0xb2/0xc4 (Errors) Feb 19 02:15:30 Tower02 kernel: [<c105ffc2>] __alloc_pages_nodemask+0x456/0x47f (Errors) I've set unRaid to use the 2nd NIC in my SuperMicro X9SCM (Intel 82579LM using E1000 driver in VM). After setting /proc/sys/vm/min_free_kbytes = 8192 I was able to get the network performance back but I'm still seeing the above errors. Any ideas? Should I passthrough the NIC instead of trying to have the guest manage it?

should i do anything about it or just choose based on serial number?

Can someone explain why the disks in unRaid (v5.12a beta) are showing up in a different order than they appear in the M1015 bios? For example I have (2) 3TB disks in my current setup and while booting i can see that slot0 has the first disk (disk0) and slot3 has the second disk (disk1) (i'm skipping slot1 & slot2 in case i add a cache drive and in case unRaid ever supports a 2nd parity drive). But in unRaid these are showing up in reverse order with disk0 = /dev/sdb and disk1 = /dev/sda. It seems like this could get confusing pretty quickly if they don't match what the hardware is showing. I hope this makes sense.

Does anyone know how hard it would be to move drives to different controllers in unRaid after having a number of drives populated with data? For example, I want to start with (3) M1015 controllers to get the best performance for now but in the future i might want to move this over to (1) M1015 and (1) Chenbro CK13601 so i can virtualize another unRaid server if needed.

So this is obviously a limitation (or shortcoming) of VMWare and has nothing to do with how unRaid handles multiple processors, correct?

JohnM (& others), How many CPUs should i assign to unRaid in my VM guest? Thanks for this great guide, I got my 2nd unRaid box up and running with the SCM-F-0, E-1240, 16GB RAM, & a M1015 card.

Thanks so much. can you answer the other part of my question: how hard would it be to re-configure the cards later if i decided to add another unRaid guest. (i.e. remove one of the M1015 and add (2) expanders using dual-link)? Doing this would require moving drives to a different controller so I'm not sure if this is possible in unRaid without wiping the data in the array. Also, do you still think the X9SCM-F-O & Xeon 1240 is the way to go for price/performance/compatibility? Or are there new/better kids on the block? thanks again.

So I'm thinking I might order (3) M1015 cards currently instead of using an expander. I'm not positive I will be adding another unRaid server in the future so I'd like to get the best performance possible and save a little money. If I wanted to add another unRaid guest in the future I could still go this route by using (2) of the M1015 cards that i buy now and buying (2) of the chenbro CK23061 (or similar), this way i only lose one of the M1015 cards (which i could use as a backup). How hard would it be to change my configuration in my first unRaid to support this new configuration down the road if I have a ton of drives with data in it? Also, will there be any issues with the 4x PCI-E limitation on the 3rd slot on the X9SCM-F-O for the 3rd M1015 card? Thanks for everyone's input so far.
