Hi again,

after getting to this: 

 

 

and changed (in order of appeareance...)

- motherboard

- RAM

- CPU

- PCIe SATA Cards (new SASLP-MV8)

- unraid version (at present 6.3.5)

- SATA cable (1 of 20)

 

tested RAM, no problems.

Nothing changed.

 

Server hangs up during parity (last time) and during Resilio activity, without any reason.

Here enclosed logs and file from FixCommonProblem troubleshooting mode.

Any ideas ?? Could be USB key ?

Any help appreciated.

That SASLP-MV8 controllers use a Marvell chipset that is problematic with unRAID. I suggest using LSI SAS9201-8i cards.

 

Not sure if that is your issue, but might be involved.

 

Someone will be able to look at the diagnostics file and may have more input.

Another idea is converting all your disks to xfs, there are various reports of v6 servers hanging with reiser.
