FreeNAS 11.1 U6 rebooting randomly when transfering via iSCSI and vmware esxi

[titanve]

Scrubbing is basically an error-check on your pool and proactively looking for any data corruption. You definitely want these running routinely as well as SMART tests.

I think SMART is not running, does it has to do with the fact that I have 2 usb drives as boot?

Thanks

"Normal" as in the defaults, but not "optimal."

Check your ESXi path selection policy, it's probably VMW_PSP_MRU for "Most Recently Used" - you want to switch to VMW_PSP_RR (Round Robin) which will cycle between all available paths:

And then change your RR IOPS limit from the default 1000 to a lower number (1 works, if you're wondering):

Hello,

Could this config affect the performance of the "regular" NIC that users use to connect to the vm inside this esxi host? Should I do any special config? My server has 4 NICs, which I am using one for users and 2 for iSCSI, I still have one available.

Thanks

No, this will only impact the storage traffic. Regular traffic should be set up with load-balancing or teaming depending on your switch capabilities.

Ok, I'm going to checkout the teaming for my my ESXi host

Thank you very much

The SMART service should start automatically once a test is configured under the Tasks folder.

Ok, I will check the smart task

Thanks
