disk-smart3: Some issue detecting disk behind a "DELL" raid card #579

Closed 10RUPTiV closed 2 years ago

10RUPTiV commented 2 years ago

Hi,

The plugin is unable to detect drive behind a DELL Raid BUT the smartctl daemon is running perfectly and able to detect as we are receiving email from the smartd daemon!

For example:

The following warning/error was logged by the smartd daemon:

Device: /dev/bus/2 [megaraid_disk_03], SMART Failure: DATA CHANNEL IMPENDING FAILURE DATA ERROR RATE TOO HIGH

Device info:
[HP       DG146ABAB4       HPD5], lu id: 0x5000c5000517eb53, S/N: 3NM1QWK600009742E1XH, 146 GB

And unable to get data from the boot disk too!

smartctl failed with exit status "Device open failed, device did not return an IDENTIFY DEVICE structure, or device is in a low-power mode."

  1. What does lsblk --nodeps --output name,type --noheadings --exclude 9,11,230,252,253,254 return? Do you see your MegaRAID devices there? Is your boot device listed?
  2. What does smartctl --xall /path/to/your/boot/disk return?
10RUPTiV commented 2 years ago

The lsblk command return

sda  disk
sdb  disk
sdc  disk
sdd  disk
sde  disk
sdf  disk
sdg  disk
sdh  disk

The megaraid disk is sdb (that's the LUN itself) and the smartctl on bootdisk give us

The output of megaclisas-status will give us:

Do you run the check plugin with root privileges? Try running it under the root account, or, if configured, try sudo /path/to/disk-smart3.

What does disk-smart3 return in case of the MegaRAID controller?

10RUPTiV commented 2 years ago

We are running the script as root for our testing!

the disk-smart3 return only

smartctl failed with exit status "Device open failed, device did not return an IDENTIFY DEVICE structure, or device is in a low-power mode."

markuslf commented 2 years ago

How does your /etc/smartmontools/smartd.conf look like?

10RUPTiV commented 2 years ago

The smartd.conf file is the default one with nothing in it except

DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runner

markuslf commented 2 years ago

Regarding smartctl failed with exit status "Device open failed, device did not return an IDENTIFY DEVICE structure, or device is in a low-power mode.": updated troubleshooting section of README of disk-smart.

markuslf commented 2 years ago

If the problem still exists, a remote session might help clarifying some things. Drop us a note at our info mail address on how to get in contact. Closing this for now as we can't help in this special case.
