SANS Digital TowerRAID TR2UT-B & ubuntu 8.04LTS

I've been wanting to try a Port Multiplier eSATA enclosure on my Ubuntu 8.04LTS Server, known as 'orac', for sometime. But, keep getting sidelined by how much it would cost to get a 5-bay enclosure and 5 drives... it would only be a matter of time that the price of drives would come down.

But, storage has been tight on my file server and it has been causing issues, and I know I'm going to have tons more stuff to add to it. The server current is just a pair of 500GB internal drives mirrored in RAID1. So, I started looking at options to add 1TB of RAID1 storage. I considered buying two discrete external 1TB drives....or buying an external enclosure that does RAID1. When I came across the SANS Digital TowerRAID TR2UT enclosure, and a few other like it....I narrowed on this one because it was under $100 and available under Amazon Prime. But, this enclosure sat in my cart 'saved for later'.

The reason I considered the enclosure was that it purports to do various RAID configurations on its own, additional it can be just JBOD and connect to a Port Multiplier port on 'orac'. If the drive didn't work on Port Multiplier, I could resort to the other options....additionally, it does USB...so if it just doesn't work on eSATA I could use it that way. Especially, should I later get 5 bay PM eSata boxes and displace this one. And, there's that thought that I might get an Airport Extreme and do TimeMachine backups to a USB attached storage....

UPS Oversight

On Monday there was a brief power outage....I didn't notice from work at first, because the UPS there were no issues affecting the computers at home that I accessed from work. Two didn't go down at all, and one rebooted by itself.

The Windows 2000 had started booting up, but since it mounts shares samba shares from the other box that didn't come up nicely...it was stuck until I told it to ignore trying to remount the share and continue. :-(

The other box is the ubuntu server where the missing samba share originates from. I had set this system up as RAID1, and one of the drives stopped working after the outage. But, ubuntu wouldn't boot without both drives. :??: Found I had to add 'bootdegraded=true' to the kernel line in grub.

Later the old APC Back-UPS Office 500 started making lots of noise. Time to replace its battery. Or perhaps time to retire it from service. I moved the loads to one of the remaining UPSs, and pulled the UPS while I investigated trade-in or replacement options.

Then this morning, I heard a strange continuous beep.....while trying to figure out where it was coming from....everything went dark. Or rather I saw my ubuntu server go down, and later on the KVM switch I saw that two other computers were booting up. Evidently, the remaining UPS was already handling too much...and its only a 700VA UPS.

I had forgotten that I had a plan to add a (Smart)UPS to the living room and move the Geeksquad 1285VA UPS eventually to run the ubuntu server (since that was the most recent addition, and it didn't have a UPS for it)....so it had been parked on the UPS that runs 'box'. Well, moving 'gumby' definitely put it over the top....probably especially with its 3 external drives. (used to be 4, but one died).

I guess it is not only time to rush on acquiring a UPS to replace the APC one that I retired, but also acquire a UPS to put the Linux servers 'box' and 'orac' onto separate UPSs.

I think I was eyeballing a CyberPower 1000VA UPS yesterday....the question is will it still go in the same place I was looking. Maybe I don't care that much about 'gumby'....though newer UPSs have lots of protected outlets, so I thought it might park nicely next to it and reduce the confusion of the which of the many powerstrips are plugged into which UPS, etc.

Am I at the point yet where a Smart-UPS can materialize, or maybe I'm looking at an additional CyberPower 1000VA (or perhaps something bigger, but still cheap)....

Hmmmm.... :hmm:

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
