[ovirt-users] Dell firmware update problem

Hello I'm trying to update the BIOS firmware on a Dell PowerEdge with CentOS (just upgraded to 7.3) running oVirt 4.0 and it fails with an error mount: /dev/sdb is already mounted or /tmp/SECUPD busy The problem is acknoleged by Red Hat and there is a solution for it https://access.redhat.com/solutions/2671581 but well, I have no RH subscriptions :( Has anyone here encountered the same problem with CentOS and oVirt? Any hint? Thanks! -- Davide
