@rvassar that looks like a great pointHave you checked your TLER settings for this drive?

@rvassar
Even i read abovementioned article, still not sure if its a good idea to have it enabled or disabled.
193 Load_Cycle_Count 0x0032 096 096 000 Old_age Always - 8011
That is increasing quickly, I saw it mentioned in here about EXOS drives having an idle timer parking the head causing timeouts when TrueNAS goes to fetch data.@cobrakiller58 seems it got increased,

Why?
@rvassar is it a good idea to enable TLER for all drive inside the raid/pool?
thanks
@cobrakiller58 no clue where are u pointing.... is that bad its increasing quickly?That is increasing quickly, I saw it mentioned in here about EXOS drives having an idle timer parking the head causing timeouts when TrueNAS goes to fetch data.
Well... Some of your drives have it enabled by default. But for the ones that don't you should enable it. Our resident Grinch has a resource on it:
Checking for TLER, ERC, etc. support on a drive
One of the problems with consumer-grade hard drives is that most of them will hang in the event that they run into an error, and will internally retry the operation, possibly for a minute or more. For a desktop PC, where redundancy does not...www.truenas.com

By that idle timer parking the head ... so its OK that i am getting timeouts on that drive?
@cobrakiller58 will check the article thanks.
by not accepting timeouts ... it means to disable ERC for all drives? or am i mixing apples with oranges?
You may want to check the manual to see if the amount of power saved is relevant to you or not.@cobrakiller58 https://www.truenas.com/community/t...een-epc-idle_a-and-idle_b-power-states.90751/
maybe it can be good just to keep idle_b set to 25min?
to completely disable - drive will increase power consumption... still not clear from abovementioned thread.
I'm curious why it has seemingly stopped being an issue though.....that issue is not happening anymore.
