I had an 8 TB External USB disk plugged into the system, that I had been using for additional space for backups, I was under the impression that sda, sdb, sdc, and sdd were the four disks on the raid controller card, but after unplugging the usb drive when running hdparm I am getting this:

[root@daisy dev]# hdparm -tT /dev/sdb

/dev/sdb: read() hit EOF - device too small  BLKGETSIZE failed: Inappropriate ioctl for device BLKFLSBUF failed: Inappropriate ioctl for device [root@daisy dev]#

------------------------------------------------------

the 3ware controller shows all four disks still online with a status of ok:

I'm still trying to find the exact smartctl command syntax to make it work.

Does this give you what your looking for? On 4/22/2020 10:08 AM, Simon Matter via CentOS wrote:

Hello Everyone,

Since rebooting my Centos 6.10 Openvz server "daisy" yesterday, I am getting horrible system performance.  /var/log/messages is full of HDIO_GET_IDENTITY failed for /dev/sdb.  The latest entries look like this:

Apr 22 08:51:32 daisy kernel: [141224.655699] CT: 1005: stopped Apr 22 08:55:04 daisy ata_id[21513]: HDIO_GET_IDENTITY failed for '/dev/sdb'

Hi,

You didn't tell us much about your hardware. It seems you're running a 3ware controller in it.

What exactly is /dev/sdb? I don't know 3ware so I can only guess but it looks to me like at least one of your drives is having problems.

Any chance you can check SMART status on the disks or have it do a SMART test? I guess your 3ware controller has to initiate this.

And, what is the status of the BBU?

Looks like "tw_cli /cx/bbu show status" should tell.

...

Regards, Simon

I tried running hdparm -tT /dev/sda, but after waiting 5+ minutes for any command output I cancelled it.

I am rsyncing the data from this system over to another system now, clearly something is wrong, but I can't tell what.

The system is an older AMD Opteron 180 processor (dual core) 4 GB ram, RAID controller with RAID 5 set up with 4x 4TB Western Digital Drives.

I rebooted the system day before yesterday, and that's when the timeout messages started pouring into the log.

when I run tw_cli /c8 show, all four drives say they are ok [root@daisy cron.daily]# tw_cli /c8 show

This is a company production mail server, and I can't find the solution, I need help, as soon as someone is able, thank you! _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Smartctl tests have passed:

[root@daisy dev]# smartctl -H -d 3ware,0 /dev/twa0 smartctl 5.43 2016-09-28 r4347 [x86_64-linux-2.6.32-042stab142.1] (local build) Copyright (C) 2002-12 by Bruce Allen, http://smartmontools.sourceforge.net

=== START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED -------------------

The problem may have been the USB disk the whole time, and not one of the internal disks, it's surprising that the performance of the entire system would suffer that much from a faulting external USB drive.

To monitor the system and ensure that was the root cause, other than hdparm, what other suggested performance tests should I run to monitor the performance of the system as a whole?  What is everyone's top rated performance monitoring commands / apps that can be dumped into cron jobs or logwatch, etc?

I had an 8 TB External USB disk plugged into the system, that I had been using for additional space for backups, I was under the impression that sda, sdb, sdc, and sdd were the four disks on the raid controller card,

Not exactly.  If you have a RAID5 array, then you have one volume spread across the physical disks.  You can then divide that into smaller virtual disks, each of which is still spread across disks.  The OS doesn't see the four component disks, directly.

...

but after unplugging the usb drive when running hdparm I am getting this:

[root@daisy dev]# hdparm -tT /dev/sdb

/dev/sdb: read() hit EOF - device too small

sdb was the disk that appeared in the kernel errors, so I'd imagine that you've fixed the problem by removing the USB drive enclosure.

...

I'm still trying to find the exact smartctl command syntax to make it work.
