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_NAM*E ( 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 - Best Regards, Leo Hsu
