根据redhat.com文章：targetcli causes calltrace with the particular partition names which include 2 digits，链接见下：
https://access.redhat.com/solutions/2180861
建议：

Currently, there is no package to fix this issue. Red Hat is handling this issue in RHBZ#1312270The workaround is to avoid creation iqn with the partition whose name contains two digits.

好吧，遇到bug了。。。不用sda10了，于是执行如下的命令：
