Horrible performance HDIO_GET_IDENTITY failed /dev/sdb

Post by cwensink » 2020/04/22 14:44:42

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 09:30:04 daisy ata_id[22489]: HDIO_GET_IDENTITY failed for '/dev/sdb'
------------------
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

We cannot support openvz systems here. They are not CentOS and do not use a CentOS kernel. At a guess that looks like either failing hardware or possibly very very busy hardware.

Thanks for the input trevor. Is there any way to tell if it's the motherboard, ram, raid controller card, etc?

Since everything there is talking about filesystems, I'd guess disks.

Update. I had an 8TB Western Digital Disk plugged into a USB port, in and I unplugged that, and in the last 15 minutes email performance seems to be better. The 3ware controller is reporting all disks internal to it are ok, and the smartctl test 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)

SMART overall-health self-assessment test result: PASSED

What other tests other than hdparm should I run to verify the issue is resolved?
