Hi

After updating to 8.3, my SR did not work anymore.
I have created it like this:

mkdir /srv/NasDrives

ln -s /dev/sda2 /srv/NasDrives/sda

xe sr-create name-label="My Nas Storage" name-description="Nas Storage" type=udev content-type=disk device-config:location=/srv/NasDrives


xe sr-scan uuid=id

This results in disks with an unrecognized bus type and 0B size.
I am therefore not able to assign this sr to a vm.

Recreating the SR in a similar manor did not help as well.

Hi, and sorry for the late reply.

Has the situation evolved in the last two weeks?

Pinging @Wescoeur and @Nambrok for insight regarding the use of the udev driver.

The udev sm driver is not PCI passthrough, it makes tapdisk directly show the block device through a PV device to the VM. I will take a look to see if there is any changes in 8.3.

@stormi thank you for the reply.
The situation has not changed (downgraded to 8.2 again).

How would I test this again, is there a patch released, or would I install again from the iso, then update with yum?
