Linux挂载存储服务器失败
存储服务器已经映射到主机,Linux可以发现,并且登录.
[root@master /]# iscsiadm -m session -o show

使用的是multipath多路径,配置如下
blacklist {
devnode "^sda"
}
defaults {
user_friendly_names yes
path_grouping_policy multibus
failback immediate
no_path_retry fail
}
可是在fdisk和partitions中没有发现,我不知道哪里出现错误了

You must set cylinders.
You can do this from the extra functions menu.
