Hi all,
I am using xen 3.3.1 with centos 5.2 on domU
and dom0. I tried to “xm block-detach” an mounted disk, it will
result failure after a long time. I type two commands after this failed detach
command , and find inconsistent of configuration:
As you see below 2 commands. (1) shows
there are two vbd. But in (2), it shows only one. This inconsistent problem
only occurs after a failed “xm block-detach”.
(1)
