Low Drive Speed Detected for all 4 Host Disks

[dreggs]

Woke up this morning to find 4 warnings on my TVS-473e, Each said [Storage and Snapshots] Low drive speed detected for disk 'Host: Disk 1' Check disk status. Then 3 more, one for each disk 2 through 4. Looked at the rapid test results and all disks show good. Is this a problem developing with the NAS? Why am I getting these warning messages?

[P3R]

What disk models and what speeds do they connect with?

Anything in the System log about it?

Look at the complete SMART information statistics (post here if you need help to interpret) for each disk and run the long tests on them.

What Firmware version and build number are you using at present?

please logon you NAS via SSH

then the following 3 commands. Post the findings back in this thread.

Code: Select all

qcli_storage -d

Since this is Beta firmware I would raise a ticket with QNAP. disk speeds look ok to me.

add the details you have run just now into the ticket as well. if smart tests have been run and nothing found then QNAP will have to investigate why the reported error.

[datorexpert]

Any RCA? Solution?
I’m using fw 4.4.1.1146.
Got a hint from the support it’s a memory issue.
Investigation continues.

[storageman]

I would suspect a cache issue, so test turning it off.
