Hi All,

I need help on this issue ,

I have 1 vm attached 4 volumes and mounted on the vm with lvm , when I do live migration from one compute node to another compute node it is failing with below error . The volume sizes , 30 GB , 30 GB , 300 GB 800 GB.

Error: Failed to perform requested operation on instance "testvm", the instance has an error status: Please try again later [Error: Unexpected error while running command. Command: multipath -f mpathcb Exit code: 1 Stdout: u'Oct 01 09:34:51 | mpathcb2: map in use\nOct 01 09:34:51 | failed to remove multipath map mpathcb\n' Stderr: u''].

Note : if I do live migration with 2 attached volumes (30 GB and 30 GB ) its working fine , this 2 volumes attached with /dev/vda and /dev/vdb.
