October 2, 201213 yr I'm not sure what is happening, but my server which has always been extremely fast has recently slowed to a crawl. No errors are found on parity checks. There are 10 data drives and parity checks used to take a day and a half. When I run one now, it is estimating over 6 days. Accessing files on the server takes much longer as well. I am attaching a syslog right after boot to see if you guys can offer any advice. I'm running version 4.7 syslog-2012-10-01.txt
October 7, 201213 yr What are the system specs? Parity check duration is based only on the size of the parity drive. My latest check took 6:42 on 3T of parity. If parity checks take more than 8 hours you should consider upgrading the hardware.
October 8, 201213 yr Author Processor is a Core2Duo with 2 GB RAM. Four of the data drives are on a slow controller but still parity checks have never taken over 1.5 days. This last on took over 4 days. I have 3 unRAID servers running and this is the first time this has happened. Nothing seems to help. Data transfers to the cache drive over ethernet average 90MB/sec. I have attached a drive list for more details on the drives themselves. As you can see the drives are not even close to full.

October 9, 201213 yr It looks like one of the drives is having problems. Check SMART reports for a drive with pending sectors.
October 9, 201213 yr Author Funny you said that. I did that earlier tonight. I have one drive (drive 9) that has over 240 pending sectors. I'm going to swap it out and see if that helps. I'm hoping that is the whole problem.
