[SOLVED] S.M.A.R.T ?

[killmasta93]

Hi,
I was wondering if someone else has encountered the Non-medium error count.
On proxmox i check the Status of the disk which shows that everything is OK .
But not sure what it means the

Non-medium error count: 222

This is the log test

Hi,
from the documentation:

non-medium error counter (only a single number displayed). This represents the number of recoverable events other than write, read or verify errors.

This means that these errors are not caused by problems with the disk itself, but maybe by a (minor) problem with cable/controller/firmware. All of these errors were recoverable and the count is rather low, so I wouldn't worry too much for the moment.

 

[killmasta93]

Thanks for the reply, whats odd normally those errors i could ignore it? but a problem with the controller? its flashed IT mode dell h310
Even though it sometimes creeps up the errors every day or week?
Thank you

 

[fiona]

Here is an example of a kind of error which increases the non-medium error counter. In that case, it's really just a minor thing.
Is there anything from S.M.A.R.T. or about the disks in your /var/log/syslog?

 

[killmasta93]

Thanks for the reply, so i should be worried when i get alerted by this
if it changes from 0 to any number?

Elements in grown defect list: 0

i havent seen anything on the syslog

 

[fiona]

Yes, that's one thing to look out for. If that number grows quickly, it's a pretty good indicator that the disk is approaching its end.
