January 29, 201115 yr Hi all I'm using UnRaid 4.5.6. We had a power outage and my UnRaid server had no UPS. When I turned the power back on, the server went through a parity check and found 6 errors. Disk6 had 944 errors (notably handle_stripe read error), and the other disks had no errors. The array is currently online. Are there recommended steps I should do at this point to inspect the integrity of the data and physical disks, especially Disk6? If I buy a retail UPS such as APC Back-UPS ES 650 VA, will I need only the presumably included USB cable to make it work with UnRaid? Which guide should I follow for the UPS setup? Thank you for your help. syslog-2011-01-28.zip
January 29, 201115 yr I just bought the BackUPS ES750 from OfficeMax for I think $69 or less like one week ago. I used the included cable that came with it to hook it up to my unRAID server. I installed the APC package and it has been working great.
January 30, 201115 yr should I run reiserfsck on Disk6? You should get a smart report on disk 6. smartctl -d ata -a /dev/sdg

January 31, 201115 yr You have 1 reallocated sector. Not a problem unless you see the number start to climb with subsequent parity checks. There have been 90 errors logged on the drive. Most recently about 3 days ago. There types of errors are frequently associated with bad or loose data connection to the disk (e.g., bad or loose cable, bad port, bad drive cage, disk not securely plugged into drive cage, etc.). At a minimum I'd recommend unplugging and replugging the data cable at both ends, or replacing the data cable.
