asked this question in the Server General forum, and have received two absolutely contradicting replies. I have searched the web for opinions dell openmanage consistency check or facts, but I can find nothing conclusive. My gut tells me it's not a good idea, because the RAID controller abstracts the physical disks, presenting a virtual disk to the O/S. Chkdsk is an O/S utility,

that can only see what the O/S can see. So when you ask it to "Scan for and attempt recovery of bad sectors", what exactly is it going to do? I don't know, and nor does anyone else by the look of it.

OH & Edit: The RAID utility should not, on such 'good controllers', be thought of as separate from the controller. Though the utility controls the process the actual verify is performed by the controller.

What kind of problems you wanna resolve. Here is an example of what can happen http://ask.metafilter.com/65106/Did-chkdsk-eat-my-files.

Tuesday, July 12, 2011 7:55 AM Reply | Quote 0 Sign in to vote Hi vind-surfer, Yes, I saw that article when I was looking for an answer. On a non-RAID drive, I would run chkdsk to fix minor inconsistencies with the file system (if any). If I suspected the drive was failing, I might run chkdsk/r to scan for bad sectors. However, on a RAID array, I wouldn't use the /r parameter because it makes no sense. I would still use the /f parameter, because I see no potential harm in doing that. And if chkdsk is not recommended for this task (fixing minor inconsistencie

array status 1.3 Simulating a drive failure 1.3.1 Force-fail by hardware 1.3.2 Force-fail by software 1.4 Simulating data corruption 1.5 Monitoring RAID arrays Detecting, querying and testing This section is about life with a software RAID system, that's communicating with the arrays and tinkertoying https://raid.wiki.kernel.org/index.php/Detecting,_querying_and_testing them. Note that when it comes to md devices manipulation, you should always remember that https://rog.asus.com/articles/maximus-motherboards/what-is-raid-setup-guide/ you are working with entire filesystems. So, although there could be some redundancy to keep your files alive, you must proceed with caution. Detecting a drive failure Firstly: mdadm has an excellent 'monitor' mode which will send an email when a problem is detected in any array (more about that later). Of course the standard log and stat files will record more details consistency check about a drive failure. It's always a must for /var/log/messages to fill screens with tons of error messages, no matter what happened. But, when it's about a disk crash, huge lots of kernel errors are reported. Some nasty examples, for the masochists, kernel: scsi0 channel 0: resetting for second half of retries. kernel: SCSI bus is being reset for host 0 channel 0. kernel: scsi0: Sending Bus Device Reset CCB #2666 to Target 0 kernel: scsi0: Bus Device Reset raid 0 error CCB #2666 to Target 0 Completed kernel: scsi: aborting command due to timeout: pid 2649, scsi0, channel 0, id 0, lun 0 Write (6) 18 33 11 24 00 kernel: scsi0: Aborting CCB #2669 to Target 0 kernel: SCSI host 0 channel 0 reset (pid 2644) timed out - trying harder kernel: SCSI bus is being reset for host 0 channel 0. kernel: scsi0: CCB #2669 to Target 0 Aborted kernel: scsi0: Resetting BusLogic BT-958 due to Target 0 kernel: scsi0: *** BusLogic BT-958 Initialized Successfully *** Most often, disk failures look like these, kernel: sidisk I/O error: dev 08:01, sector 1590410 kernel: SCSI disk error: host 0 channel 0 id 0 lun 0 return code = 28000002 or these kernel: hde: read_intr: error=0x10 { SectorIdNotFound }, CHS=31563/14/35, sector=0 kernel: hde: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error } And, as expected, the classic /proc/mdstat look will also reveal problems, Personalities: [linear] [raid0] [raid1] [translucent] read_ahead not set md7: active raid1 sdc9[0] sdd5[8] 32000 blocks [2/1] [U_] Later on this section we will learn how to monitor RAID with mdadm so we can receive alert reports about disk failures. Now it's time to learn more about /proc/mdstat interpretation. Querying the array status You can always take a look at the array status by doing cat /proc/mdstat It won't hurt. Take a look at the /proc/mdstat page to learn how to read the file. Finally, remem

And Setup Guide For First Timers Articles: Motherboards Motherboards Crosshair Motherboards Motherboards Guides Article Tags: Guides Note: This article was updated in September 2014.RAID Setup Guide.What is RAID? A Redundant Array of Independent Disks, or RAID, is a way of storing the same data across multiple hard drives. Almost all have redundancy to offer some data protection, while RAID 0 is built purely for speed. NOTE: redundancy is NOT a form of backup!There are many ways to use RAID and there are several different types of array. Some use multiple disks to increase performance – think a two or three lane road instead of single, that has to serve traffic going in two directions – while others are used to increase reliability. Additionally, there is a third type of RAID that offer the best of both worlds; all of which we've explained below.A RAID array appears to the operating system to be a single logical drive, regardless of how many individual drives are part of the RAID array. Both hard disks and SSDs can be used, and while it's advised that matching drives are used in a single array for best performance, it's not strictly required.This article focuses on setting up a RAID array with an Intel motherboard for the single user. The Rampage V Extreme's SATA and SATA Express ports connected to Intel's X99 chipset support RAID 0, 1, 5 and 10 modes.What kinds of RAID are there?I know of 9 different kinds of RAID plus a performance RAID that has no redundancy built into it, however on everything outside of the high-end server environment you'll only be offe
