May 29, 201115 yr Hi guys, I've been using my unraid server for the past month. I'm starting to face some problems now. First, I got 5 new HDD's and precleared them then put them in the server. I then moved all data from my old HDD's to the unraid server then precleared the old drives to make sure they're good before putting them on the server. As far as I know they all passed and there were no relocated sectors even though 1 drive showed that 1 sector was relocated and another one supposedly failed but with no relocated sectors but after I ran the preclear on them again they passed with no issues so I thought it must've been the load on the server because I was preclearing them all at the same time. I installed a cache drive when I built the server but somehow now it's not showing. And today I started a parity check and found a lot of errors. Could someone please take a look at the syslog and point me in the right direction. I don't know what the issue is or how to fix it. Thanks in advance. syslog-2011-05-30.txt.zip
May 30, 201115 yr Author When I tried to obtain a SMART report of the parity drive I got this response to the smartctl command : smartctl 5.39.1 2010-01-28 r3054 [i486-slackware-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Smartctl: Device Read Identity Failed (not an ATA/ATAPI device) A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options. I rebooted the server and now unRaid is telling me I have a new parity disk installed. I haven't started the array but I tried to obtain the SMART report again and the command ran successfully. Here's the output for the drives you requested. I use an old Gigabyte Odin Pro 800w PSU (http://www.gigabyte.com/products/product-page.aspx?pid=2493). Thanks for your help dgaschk disk7.zip parity.zip
May 30, 201115 yr This is possibly a power supply problem. The Gigabyte Odin Pro 800w PSU has 4 12V rails. Two of the rails are 18A each and 2 are 25A each. If one of the rails is overloaded it could cause the problems your seeing. See here for info on power supplies: http://lime-technology.com/forum/index.php?topic=12219.0
