Unraid upgrade from 6.12.14 to 7.0.0 seemed to be flawless in the first moment.

 

B U T  !

 

After 7.0.0 was installed, I wanted to make a new backup of the important parts of the server to my external USB 8TB backup HDD (rather new Seagate Exos type) as usual... (using famous rsync script of @mgutt)

 

However with the new system it doesn't work any more or is so slow, that the  it is useless...

 

Here is a typical message of syslog... it goes like this over thousands of lines in the syslog:

 

 

I have read in the release notes of Unraid 7.0.0, that there is a change with Linux Kernel about external Usb storage devices (like my external USB HDD is):

"...Other changes: ...

Linux kernel: force all buggy Seagate external USB enclosures to bind to usb-storage instead of UAS driver ..."

 

Question:

Could the fault with my external USB drive have to do with some Linux Kernel change causing incompatibilty problem between my USB hardware and new Linux Kernel ??

 

What should I do, in order to be able to take back-ups to that USB drive as with 6.12.14, which never had that problem ?

Perhaps there is some settings problem or anything else, I can do

 

Many thanks for support and greetings

 

P.S. diagnostics file attached...

It's a Seagate disk but not a Seagate enclosure, right? Also, post the output from

lsusb -t

 

Thanks for quick answer, @JorgeB - great support with so many people asking many things...

 

Yes, it is a bare Exos harddisk but not a Seagate enclosure/product which contain the harddisk.

 

So lsusb -t returns:

Additional Info:

The harddisk is a bare harddisk Exos 8TB - for backup purposes, I quickly insert the HDD in a USB docking station from Sharkoon.

It has the advantage, that after the backup I can take the HDD out of the docking station and store it at a different place outside of my home at a save location.

 

The HDD has no smart errors

Perhaps the UAS driver needs to be disabled - but I do not know, how to do this with the Unraid server to work correctly.

 

Thanks for info

Possibly, that enclosure doesn't like the UASP driver, try adding the below to syslinu.cfg for your default boot mode:

 

usb_storage.quirks=152d:9561:u

 

After /bzroot, then reboot

your advice solved my problem...

excellent support!
