Bizarre CHKSUM errors

[bellmr]

I am a relative newbie, but have a bit of a grasp on TrueNAS. My problem is that one of my pools is showing as unhealthy, and all the drives in that pool are showing the same numbers of CHKSUM errors. If the server is rebooted, the error count drops to 12 (or maybe less), but one can see it climbing steadily, and each of the four drives shows the same number of errors. I have done scrubs, but nothing seems to help. smartctl for each drive shows no errors, but zpool -v status shows the below : (this is after the server has been up for 2hrs 47mins, so shows the steady climb of the CHKSUM errors on NAS_Volume

zpool status -v

Code:

codeblock
zpool status -v


  pool: Jails_Vol


 state: ONLINE


status: Some supported and requested features are not enabled on the pool.


    The pool can still be used, but some features are unavailable.


action: Enable all features using 'zpool upgrade'. Once this is done,


    the pool may no longer be accessible by software that does not support


    the features. See zpool-features(7) for details.

Hope someone might have an idea why this is occurring, or what else I can do to rectify or identify faults. All of the drives are SATA using the mobo onboard connectors, I have change all of the SATA cables, changed the PSU, now I am wondering if the mobo is damaged.

Wait for the scrub to finish.
Please provide your hardware specs, and after the scrub is completed the result of SMART long tests.

This looks like a cable or controller issue.

Hi Etorix,

That's what I am thinking. I have changed the cables, the power cables, and the power supply, so my thoughts were with the mobo now. But the fact the 5th drive doesn't show anything and its only in the NAS_Volume pool is tripping me. When the scub has finished and

Code:

smartctl

has finished I should have further info.
