The partition table has been altered!
Calling ioctl() to re-read partition table.

最后一个w是把分区信息写入磁盘并退出fdisk。
然后执行fdisk -l
[root@192.168.14.117:/dev]#fdisk -l

得意忘形了一下，然后直接执行
mount /dev/sdc1 /datalog
就被泼了冷水
[root@192.168.14.117:/dev]#mount /dev/sdc1 /datalog
mount: you must specify the filesystem type
[root@192.168.14.117:/dev]#mount -t ext3 /dev/sdc1 /datalog
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or other error
(aren't you trying to mount an extended partition,
instead of some logical partition inside?)
In some cases useful info is found in syslog - try
dmesg | tail or so
才想到创建了逻辑盘还没有创建逻辑分区呢，也没有创建文件系统，然后再执行一下：fdisk /dev/sdc
Command (m for help): n
Command action
l logical (5 or over)

l

再查看一下
