MicroServer FreeNAS project Update! Part 2
Turns out that the spare Hynix ram I had lying around was ECC registered! Unfortunately, the Gen8 micro server only takes unregistered DDR3 which is kinda expensive (when compared to registered). Through some research, though I discovered that the gen8 server is rather picky about what unregistered DDR3 you put in it.
I used the gen7 micro-server wiki to view what ram it accepted and was met with a rather small list of verified ram that works, Kingston was the brand and only 3 sticks were certain to work. I have spent quite a bit of time on eBay looking for a reasonably priced stick of the stuff (hence the long time before this update post) and they were averaging around 100-140 AUD per stick. This was a bit frustrating as I bought 32g ecc registered from china for 130 aud delivered! I had been spending some time just fluffing around until I found some NEW hp OEM memory, the very sticks that were certified by HP and on their spare parts list! I had struck gold after some cheeky eBay sniping i won the eBay auction, however, the guy took almost over a week to ship the item and I started to get worried, when he did ship it a shipping number was provided and was here in a few days (eat your heart out aus post). Everything is almost ready!I have almost gotten everything to finally build the entire FreeNAS project. All that is left now is to buy some new drives for it! I've got some older drives sitting around that I am going to use as a temporary stop-gap so I can install FreeNAS and have a bit of a play.
Here is that post that I talked about, so in it ill be having a look at Open Media Vault and Nas4Free! The system I am testing on is an Intel sg2600gz, a pair of Xeon E5-2650 @ 2.0GHz with 32gig rddims @1600 and raid 1 10k 6gig SAS drives. I know the SAS drives will bottleneck the system so any performance tests are going to be a little lacklustre considering they are also running a few other OS on them. To test the transfer speed I will copy a single 20 gig VMDK file FROM an SSD to ensure the source is not the bottleneck. VM’s are running on ESXi-6.5.0-4564106. Open Media Vault Ver used: 3.0.86 vCPU’s=2 Ram=2gig 5 16 virtual disks (thin) The install process was super easy, just like installing a copy of Debian, once that was all done when to go check out the web UI was it was incredibly clean and responsive! The storage page was layout was simple and easy to understand however I tried to change some settings other than the default raid ones but I found myself unable to d...
So after having a poke around the unit i found out that “On buck” basically means that the incoming voltage from the wall was higher than the output voltage of the unit, so after reading the PDF manual I discovered that I had to set the rear switches to a specific way in order to accommodate the voltage and clear the “On Buck” warning. Switches are now set at 240V based on the conveniently placed diagram However upon testing the batteries of the unit and how long it would last I discovered that the “good” batteries were, in fact, no good! I tested them by putting my laptop charger on the UPS and then unplugged it from the mains, within 30 seconds it died and I was confused and assumed that the unit was dodgy. But I thought I should at-lease check the batteries when the unit was under load to check they were outputting the correct voltages! I pulled the front panel off the UPS and found the battery tray just slides out, handy! The batteries were stuck to the tray and each-other w...
So I was updating my home network now that I have a separate server to handle the pi-hole and DHCP/DNS requests, I decided to fix my VMWare setup. I was using IP addresses because I did not have a proper DNS setup and it caused all sorts of issues (i was running a pi-hole VM inside ESXi off my server), now that all that has been updated and sorted, ESXi was all happy and I could use its name in the web browser! However after updating my vCenter IP, I have run into the Error 503 page, after a quick google, the internet said I should check if the vSphere client service is running! I went to the appliance page and that was running, so I enabled SSH and BASH then SSH into the appliance to check of the service was running. service vSphere-client status While I was in the shell, the internet said I should check the HOSTS file if the IP is correct and matches, turnout it does not match… vi /etc/hosts Using VI I changed the IP to match the one on the appliance page then stopped a...
