Hello folks,

 

I'm looking for some assistance here. This is the second time two disks have gone down at the same time. Last time I replaced the two that failed with the exact same drives, zeroed them and got zero errors and they've been running fine every since. Now, I woke up this morning to two more drives down, one which is a parity drive, but these both are brand new drives and I zeroed them out when I added them to the array. Does anyone have any ideas what might be going on here? I am uploading a diagnostics bundle.

 

Thanks.

You are using two SAS2LP, it's a known issue with them, recommend replacing them with LSI controllers, 9201-8i, 9211-8i and clones.

So you’re saying the only way to resolve this issue is to buy two new SAS controllers? I read somewhere that disabling all the VM stuff might help, would that fix the issue?

It might, you'll need to try for yourself, board bios update can sometimes help also.

Do we have any idea if the 6.4 version might support SAS2LP?

 

Thanks

Its not unRaid per se, but rather the drivers from Marvel combined with motherboard / harddrive combinations.  Its kinda hit and miss sometimes.  I for one have no issues with the controllers randomly dropping drives, but some users do.

 

Some (but not all) of the Marvel issues are proven to be directly related to certain hard drives: https://forums.lime-technology.com/topic/59091-marvel-issues-starting-point-for-investigation/

Are there any steps I need to take before replacing my SAS2LP SAS cards with LSI SAS? I have the new hardware now, do I just shut her down, yank the old and plug the new and start it back up?

Should be enough but always good to at least have a screenshot of current assignments.

That is what I did when replacing my SASLP controllers with a LSI one.   Just swapped the SAS cables to the LSI controller and I unRAID came up working with no further action required.
