Rmove a faulty hard drive off LVM Group

Hello,

My system is a Sun Fire X 2100 with RHEL 4.0. It has two 80G
ATA SCSI disks. Right now, one of them is failing, and I need to remove it off
the LVM Group.

Here is the LVM layout:

# df -k

Filesystem          
1K-blocks      Used Available Use% Mounted on

/dev/mapper/VolGroup00-LogVol00
                     151527604 
15281032 128549372  11% /

/dev/sda1              
101086     18896     76971  20%
/boot

none                
  1036912        
0   1036912   0% /dev/shm

But when I run vgdisplay, the system only have 160MB Free
PE.

# vgdisplay

  --- Volume group ---

As the usage is only 11% for VolGroup00-LogVol00 as shown by
“df –k”, I don’t know why I only have 160MB PE free. 

I tried “pvmove /dev/sdb1”, got the error
message “insufficient suitable contiguous allocatable  extents for
logical volume pvmove 0:2384 more required, unable to allocate temporary LV for pvmove”.

Can someone please help me out?

Thanks a lot in advance,

Joann
