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 -
