[Clonezilla-live] linux raid1 image on pendrive

[mangesh s. <man...@ya...>]

hi,
 
 
 I have installed CentOS 6.3 x86_64 on Gigabyte motherboardH61, Core i3processor, 2GB ram and 80 GB *2 Hard disk for raid1. where /partition is 20 GB(MD0) swap is 2GB and /home is 2GB(MD1).
 I want to take the image of the full disk on 8 GB Pen drive,  it gives me error insufficient disk space after 86%, where as earlier I created a disk image and partition image both of 2TB drive on 8 GB pen drive only . I don't know am I missing some thing ?
 
Sorry I'm new to CZ as well as Linux and appreciate any help
 
 
Regards
Mangi
