[linux-lvm] Snapshot Problem JFS

["David Sornig" <dsornig lbmc com>]

I am running RedHat 9.0
Kernel 2.4.20-8
LVM Version 1.0.5+(22/07/2002)
 
I have a 1.4T LogVol with 400G of space being used on a JFS file system.
 
The LVM is working excellent.  However,  I cannot create a snapshot.  I run the following lvcreate command as per the man page and get the following error:
 
lvcreate --error "Cannot allocate memory"  creating VGDA for "/dev/Volume00/snap01" in kernel
 
Not sure why this is happening.  I have read the list and maybe I just don't understand the problem.  These servers have 4 Gigs of RAM.
 
Regards,
 
David
