很好，一切正常
4、创建文件系统
执行mkfs.ext3 /dev/sdc5
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
2621440 inodes, 5241190 blocks
262059 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=0
160 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 33 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
正常
5、挂载到根目录下的datalog目录
mount /dev/sdc5 /datalog
再执行df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda3 18020368 15983692 1106516 94% /
/dev/sda1 256666 15923 227491 7% /boot
tmpfs 777688 0 777688 0% /dev/shm
/dev/sdb3 30961664 24018284 5370620 82% /data
/dev/sdc5 20635668 176200 19411232 1% /datalog
都正常了。完美解决。
