AIX扩展文件系统

1. 扩展LVM

   [root@aix /]# extendvg datavg hdisk12
   0516-1254 extendvg: Changing the PVID in the ODM.
   [root@aix /]# chfs -a size=+100G /oradata
   chfs -a size=+100G /oradata
   chlv �Cx 8000 oradata
   Filesystem size changed to 3985637376
   [root@aix /]# lslv -L oradata
   LOGICAL VOLUME:     oradata                VOLUME GROUP:   datavg
   LV IDENTIFIER:      00f7609300004c000000013f2cebbbf9.4 PERMISSION:     read/write
   VG STATE:           active/complete        LV STATE:       opened/syncd
   TYPE:               jfs2                   WRITE VERIFY:   off
   MAX LPs:            8000                   PP SIZE:        512 megabyte(s)
   COPIES:             1                      SCHED POLICY:   parallel
   LPs:                4201                   PPs:            4201
   STALE PPs:          0                      BB POLICY:      relocatable
   INTER-POLICY:       minimum                RELOCATABLE:    yes
   INTRA-POLICY:       middle                 UPPER BOUND:    32
   MOUNT POINT:        /oradata               LABEL:          /oradata
   MIRROR WRITE CONSISTENCY: on/ACTIVE                             
   EACH LP COPY ON A SEPARATE PV ?: yes                                   
   Serialize IO ?:     NO          
   

2. 扫描新的磁盘：

   添加新的磁盘后，在AIX系统用cfgmgr 扫描新的磁盘
   

3. aix删除文件系统操作：
   umount /dev/folback
   rmfs /folback
   rmlv: Logical volume folback is removed,
   就可以释放空间了
