180 days, whichever comes first.  Use tune2fs -c or -i to override.
建目录
[root@jusdoi ~]# mkdir /u01
mount
[root@jusdoi ~]# mount /dev/VolGroup01/u01 /u01
查看已经mount上了
[root@jusdoi ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup01-LogVol00
                       20G  2.3G   17G  13% /
/dev/sda1              99M   14M   81M  15% /boot

/dev/mapper/VolGroup01-u01
                       15G  166M   14G   2% /u01
为使重启后生效，修改/etc/fstab
/dev/mapper/VolGroup01-u01  /u01                ext3     defaults        0 0
