Subject: [Xen-users] Xen boot file
Hey All,
I have created one big gfs volume approx. 136GB and I 
have exported 
it through gnbd and successfully imported it and mounted it. 
My idea is 
to install a bunch of xen instances to files on the mounted 
gfs volume. 
But everytime I go to install using virt-manager it give me 
this error. 
"Could not allocate requested partitions: Adding this partition would 
not leave enough disk space for already allocated logical volumes in 
VolGroup00.." Should I split the storage up before exporting it?
 
I think you have two possible solutions: 
1. You use FILES within the GFS volume, which means that the file would
just be one of many files. 
2. You use individual (LVM) volumes for each guest, in which case you
need to split the it into (potentially many) logical volumes. 
I suspect there are good and bad reasons for both, but I don't think it
makes much of a difference performance-wise whether you have one large
volume with many individual files or one volume per domain - at least
not if you don't have HUGE traffic to/from the GFS volume.
