Extending a VxFS Filesystem (No Online JFS)

Extending a VxFS Filesystem (No Online JFS)

1. Verify that there is enough space in the volume group
   • vgdisplay <VG Name>
   • If there is not enough space then the volume group must be extended - see procedure below.
2. First lvextend the logical volume - 2 Options for lvextend:
   1. lvextend -L <New Size in MB> /dev/VG_NAME/LV_NAME
      
   2. lvextend -l <NEW Size in # of LEs> /dev/VG_NAME/LV_NAME
3. Unmount the filesystem
4. extendfs -F vxfs /dev/<VG_Name>/r<LV_Name>
   • Note:  extendfs uses the raw logical volume name (ie rlvol1)
     

How to determine if you have Online JFS

• swlist -l fileset | grep -i advanced

How to determine the filesystem type

• grep <mount point> /etc/fstab
• Results should show the filesystem type (vxfs or hfs) in the return string
