Thanks. From what I've just experienced, running SMART monitor tools (`smartctl`) every now and then to check drive health is crucial - especially if used in a server environment. At least glance at the wear-level and re-allocated sector count to see if it's rising. When my system is back...

Well in that case the number is 33170, which crazy high. The SSD is f*****

Thanks, good input here. I'll try to set swappiness to 1. Logging I don't think I'll worry about..

Good thought, thanks. What can one do to prevent excessive swapping? I had the standard partition-setup that is set up when installing Ubuntu to a single disk without LVM, all defaults. No other OSes. The system has 8GB memory, which I've never seen to be eaten up. Would 16GB seize the...

Update: Reallocated sector count of 8192 is really high. Quoting Samsung (its a Samsung SSD), this number "represents the number of sectors that have been moved as a result of a read error, write error, or a verification error". I'm starting to think this SSD is on its deathbed.. Oh, and...

Thanks for the tip. I have the data backed up so thats not actually my main concern. I'm more puzzled as to what happened (how partitions suddenly disappeared), and worried that the SSD has failed, so that something similar can happen in the future if I re-install the OS. Looking at the...

Hi all I have a NAS/home server running Ubuntu 14.04, with a 128GB Samsung SSD as root (OS) disk and a 4-disk mdadm array for storage. The system has been running fine for 4 years. I've got a CRON script that regularly checks CPU temp, and shuts down the machine if temps exceed 80C. It...

I'll see what I can do, just gotta install a game on my Mac then.. Shipping date of my order has been updated to jan 23rd. Forgot to mention, the monitor was surprisingly cheap here in Norway, costing the current equivalent of about $370. Not sure whats up with that, to be honest, it being...

I also think the size/resolution compromise here makes a lot of sense, excited about this monitor. I write code for a living. They just came up for sale here in Norway, and I ordered one, although it looks like delivery times are > 7 days.

For anyone interested, here is how I ended up solving this challenge: To recap: I had a mITX board with 6 sata plugs, with an SSD for the OS and 5 2TB disks for the array plugged in. I wanted to migrate that array to a 4x 4TB disk array. Firstly, I backed up my entire array to another backup...

It turned out all my new 4TB disks were bad. Should have expected the worst when I saw how poorly they were packaged. After receiving new disks from the dealer, I stuck to the plan and tried again; degrade existing array to four drives, create new degraded array using two 4TB drives, and copy...

Thanks. Im learning some new things here. Does a long test using 'smartctl' suffice as a test of disk failure? 'badblocks -wsv' is taking years to complete.. I'd like a pre-test that can indicate to me what the most obvious errors are.

Thanks. In theory it should work fine, but folks are trying to scare me here. Granted, I will run without redundancy for at least a few days while the operations run. I read a guide that suggested I created single primary partitions on the disks of type "Linux RAID autodetect" before...

Thanks omniscence. What I'll do is test all the new disks thoroughly and verify the whole system. Then I'll plug all 2TB disks back in and run it back to non-degraded mode. Then I'll bring my backup-server around and use it to aid the data-transfer.

Yes I have a machine at my parents house with a similarly sized array that I rsync important data to at set intervals. That is my backup. I didnt think initially that this was so risky - Im running both arrays degraded for a period of a few days while the operation is underway, what are the...

What I ran was the following: sudo mdadm --create --verbose /dev/md1 --level=5 --raid-devices=3 /dev/sda1 /dev/sdc1 missing which successfully created the array. Then I ran sudo mkfs.ext4 /dev/md1 to create a filesystem on the new array, which caused the array to fail. Resulting output of...

Thanks for input. To clarify, heres what I want to do: I have 6 SATA ports, and an existing 5x2TB RAID5 array, and in addition a single SSD with the OS installation. I want to move to a 4x4TB RAID5 array. So the plan is to 1) unplug the SSD and one of the 2TB drives so the existing...

Hi Due to some special circumstances I need to create a RAID5 array with two disks, i.e. a degraded array with one drive "missing", using mdadm I have two 4TB disks. What I've done is booted up Ubuntu 14.04 using a Live-CD. Then I created a single, primary partition on each of them of the...

Hi guys I've tried everything and read the internet but my Ubuntu server/nas/mediacenter is rendered useless and I really need some pointers on how to get it running again. Long story short: While upgrading to the latest kernel, v 3.13.0-24, I got a message saying that /boot partition was...

SORRY, scratch the LVM comment - that is on my OS disk only

OK thanks. Good point, that should work. Oh btw, my array is on top of LVM.. Perhaps another good reason to re-create the array from scratch. I dont even remember why I used LVM

Thanks for lots of good input guys! Yes, patrickdk you are spot on, I only have 6 ports on the mobo (its a Mini ITX rig) and atm 5 are used for the array and 1 for the OS (SSD). So while I wish I could, I cant plug in two 4TB drives to temporarily copy over data. I do of course have a backup...

Thanks! If it actually works, this sounds like the best option so far. Didn't know you could resize I'm degraded mode. So the steps would be * Replace four 2tb disks (which are in hot swap bays) with 4tb disks, one by one * Remove one 2tb disk, failing it and leaving the array in...

Thanks for input guys. I've gotten confirmation that my plan will work (a friend has done something quite similar), but it certainly is a daunting task. I am inclined to just do something like ezno_matrix suggests and copy the files off the array, build a new array with the new disks and copy...

Thanks, I'll look into it. I'm also using ext4. Spot on! Except I'm replacing the 2TB disks with 4TB disks. Had a typo in the first post, I'll correct it. But glad to hear you think it will work. Its really step 1 I am most worried about. And the fact that you havent had sucess shrinking...

Guys, Im running RAID5 using mdadm on my Ubuntu 13.10-based server. I've currently got a 5x2TB array, but I need more space and want to grow it to 4x4TB. I think its possible, but I realize its not trivial. I'd like appreciate some input to ensure I'm on the right track with my plan. What I...

+1, good idea. And I wouldn't mind the extra "insight" into the components of the case..

Thanks, yes it was exactly the point that you noted the top panel getting so warm that made me think getting the hot air OUT not IN would be desirable for the mobo chips etc (non-WCed components). But temp. delta for the water wins in terms of priority anyways I guess.

I'm interested in this as well. I've been following the thread for months but I can't remember seeing this discussed. If we ignore the dust reduction advantages of keeping a positive pressure in the case, what are the real downsides to using these fans as exhaust? If both CPU and GPU are...

Oh great news! I'll be getting a regular 670 with a WC block then. If I understand it correctly, a WCed 670 should leave room behind the PCB for a fullsize ATX PSU. But that PSU will take up space needed for the radiator+fans on the side-cover, so if I wanna WC I need an SFX PSU (given I want...

That card looks super nice, perfect for a build like this. And no sacrifice on performance either, they just cut down on size. I assume the current generation of GeForce 670 waterblocks won't fit that card? So unless a custom block is made for it (unlikely?), this card rules out GPU WCing, or...

Awesome, thanks for pics and info! 85mm between fan bracket and SFX PSU minus 54mm for fan & rad leaves 31mm for fittings and tubing, did I get that correct? If so it should be plenty, any 90 degree fitting with OD 1/2" or less should fit

Fantastic idea and awesome design. Hats off to you guys! I take great joy in building neat WCed systems as they present challenges when it comes to tubing, cable routing, choosing parts and making things fit. This could be a great powerful WC system with careful planning and the right parts...

Like NickTheNut says, yes, essentially. You'll find plenty of tutorials online, and the typical scenario is that a designer has created a fixed "image" of the website in photoshop, and it is a developers job to create a web page that resembles the design. This is done using HTML with CSS...

Thanks. I've found plenty of tutorials and guides on PSD to XHTML/CSS, so I should be set for the weekend when it comes to ploughing through it and getting started. Few of those I found are more recent than since 2009, however. Are they still "up to date", meaning has CSS or XHTML changed any...

Thanks guys. Yeah the mockup is really nice and clean, all that changes between the 55 pages are two content areas and menus with their hover-states. I also want to have full control over the code for the site and I wasn't really planning on having the code auto-generated. At a later...

Hey all, I am making a website for a friend, and I have been provided with the complete site design in the form of an InDesign project that can be exported to HTML. It is 55 pages (images, really) complete with graphics, hover states for buttons etc. What I need to do is chop it up into...

LOL

It is an absolutely gorgeous game on the PC. The battlefield is more intense and involving than ever. This video highlights its beauty effectively: http://www.youtube.com/watch?v=VlF6pvqa3Qg&feature=player_embedded#! Yeah I agree some quirks could be worked out with Origin/Battlecom. I dont...

Thanks!
