Strange error - bad block

[zablowoj]

Hi,

I have raid controller with configured 2 logical devices with raid 5 protection. On web gui in open-e i recently have 4 srange errors:

2009/02/03 22:35:20 [418] Bad block discovered: controller 1 (642f000).
2009/02/03 22:16:57 [418] Bad block discovered: controller 1 (15ec800).

2009/01/27 00:47:50 [418] Bad block discovered: controller 1 (bd7a100).
2009/01/27 00:47:40 [418] Bad block discovered: controller 1 (bd7a000).

I verify health of physical disck's and logical disck's - all are ok.

When a bad block is discovered in a particular disk the bad block is then remapped within the remapping pool and is stored across multiple disks. I would contact the RAID manufacture and ask to assist you on a deeper investigation. Please back up your data!

I would start with the basics and run the memtest and then the file system repair utility - if you are using NAS.

Memtest is done by rebooting the system and after POST hit the ESC or TAB key there you will see the basic menu - run the memtest for at least 45 min. If now errors then reboot and go to the Console screen and enter CTRL + ALT + X then run the File repair option.

Only do this if you are absolutely sure your RAID set is good!
