Hello all,
I have a question. But my English is very poor, I
hope you will understand
My VM has one virtual disk which allocated 100G
I find the utilization of this disk in guest
OS is 39.5G ( Get utilization on
guest OS file system)
but I ssh to
the NFS server check the VHD files size
I use
command: ls -lh VHD_FILE_NAME ( Get utilization on NFS server file
system)
It show
that
-rw-r--r--
1 root root 19G Jan 22 2013 XXXXXXX.vhd
Then, I use
command: du -sh VHD_FILE_NAME ( Get physical
utilization on disk )
It show
that
5.5G XXXXXXXX.vhd
My
question is what happen in this process ( 100G
-> 39.5G -> 19G -> 5.5G )?
Are they representing XenServer's
thin provision, VHD's
thin provision and File
System sparse file ?
Does
XenServer's thin provision equals VHD's thin provision? VHD's
thin provision equals File System sparse file ?
If yes, what
happen in this process?
Thanks
