ESX4.1 修改文件块大小

Reconfiguring the ESX 4.x installer and formatting new VMFS volumes with a specific block size

To reconfigure the installer to format VMFS partitions with a specified block size:

1. Boot the ESX installation DVD and choose Install in graphical mode.
2. Press Ctrl+Alt+F2 to switch to the shell.
3. Run:
   
   ps | grep Xorg
     
4. Kill the PID which shows Xorg -br -logfile .... 
    
   For example, run:
    
   kill 590
    
   Where 590 is the PID, per above.
    
   Notes:
   
   • If you specified a GUI mode installation, killing the process identified as Xorg may switch you back to another console. If this occurs, press Ctrl+Alt+F2 to return to the previous console.
   • If after killing the Xorg process you get the message "Press <return> to reboot", press Ctrl+Alt+F3 to go to another console and continue working there without rebooting.
    
5. To switch to the configuration directory, run:
   
   cd /usr/lib/vmware/weasel
      
6. To edit the configuration script, run:
   
   vi fsset.py

   Note: Press i for insert mode.
    
9. To save and close the file, press Esc, type :wq! and press Enter. The exclamation mark is needed to force the action of saving as the file is read only.
