Re: 3PAR - Thin Persistence with Linux?
Hello,
you have to fill the filesystem with zeros. This can be done by a simple script. Before starting the process check the free space on the volume. This can be done by "df -h". If you have 23 GB of free space, use this command:
[root@rhel5 /] # mkdir /zerofree
[root@rhel5 /] # for ((i=0;i<23;++i)) do
> echo Generating file /zerofree/$i ...
> nice dd if=/dev/zero of=/zerofree/$i bs=1k count=1m
> done
Check this doc:
http://communities.vmware.com/servlet/JiveServlet/previewBody/11209-102-1-10301/vmf2t-wp-09.2.pdf
The same command is listed at chapter "3.2.1 Zeroing Free Space: Linux Guest OS"
Regards,
Patrick
