Package: linux-image-3.2.0-5-amd64 Version: 3.2.96-3 I updated my wheezy kernel because of the meltdown patch.
After the update two commands are not working anymore: 1.) tw-cli show 2.) smartctl -a -d 3ware,0 /dev/twa0 I have a 3ware raid controller with 6 disks and these disks are configured as PVs in my LVM: The LVM can see the disks behind the raid controller (Model 9500S-8), only the above cli tools are not working anymore.
