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...
