Man, I really love it when things work the way they are supposed to.\u00a0 Last night I fired up my notebook to check some emails and to pull up a technical manual that I wanted to read.\u00a0 The manual was located on a RAID (Redundant Array of Independent Drives) drive downstairs in the radio room.\u00a0 But after checking my Emails I could not access the RAID drive.\u00a0 I went downstairs to see what was wrong and discovered my RAID box was showing an error on one of the drives and had shutdown.<\/p>\n
For a number of years I have used a RAID on Linux server to save files and backups from our computers in the house.\u00a0 The RAID was a home-brewed computer running Redhat Linux 9.\u00a0 Unlike a Windows computer, this one ran without a single hitch for years. Over that time I collected about 200 Gb of various files and backups.\u00a0 Finally after about 6 or 7 years the power supply failed in that computer.\u00a0 I replaced the supply in the computer and was back up and running.<\/p>\n
Since the computer I was using was quite large and consumed a lot of power and took up a lot of space, I decided to upgrade to a Buffalo Terrastation NAS (Network Attached Storage) system.\u00a0 I bought one from www.ecost.com on close out for just over a hundred bucks.\u00a0 It was a terabyte box, with four 250 Gb drives.\u00a0 In the RAID 5 configuration it had just at 700 Gb of storage, more than adequate for my uses. RAID 5 uses one of the disks in the array as a parity disk so that if any single disk in the array fails there is enough data on the other drives that the array can be rebuilt.<\/p>\n
When I retired the old Redhat Linux server and RAID I saved a couple of 250 Gb IDE drives from the old RAID server just in case I ever needed a spare for the Terrastation.\u00a0 Well, I needed one last night.<\/p>\n
Just as advertised, I replaced the failed drive in the Terrastation, booted it back up, logged into its HTML interface and rebuilt the RAID.\u00a0 The rebuild took overnight, but in the morning all my files were back!\u00a0 Whew!\u00a0 That was close!\u00a0 I really like these computers when they work the way they are supposed too!<\/p>\n","protected":false},"excerpt":{"rendered":"
