Hi, all:
ÂÂÂÂ At first I have an idea to improve the performance of the log mechanismÂin ext3 file system of DomU, but when I do some experiment in DomU, I find a strange thing.
ÂÂÂÂ When I input command "df -lhT" to see the file system type, it shows that it is ext3. But when I input command "cat /proc/mounts", it shows that "/dev/root / ext2 rw".This means the type is still ext2. So I can't do my experiments.
ÂÂÂÂÂ# df -lhT
 >Filesystem Type Size Used Avail Use% Mounted on
ÂÂÂÂ >/dev/sda1ÂÂÂÂ ext3ÂÂÂ 9.2GÂ 3.7GÂ 5.1GÂ 42% /
ÂÂÂÂ >tmpfsÂÂÂÂÂÂÂ tmpfsÂÂÂ 129MÂÂÂÂ 0Â 129MÂÂ 0% /dev/shm
ÂÂÂÂÂ
Â
ÂÂÂÂ # cat /proc/mounts
ÂÂÂÂ >rootfs / rootfs rw 0 0
ÂÂÂÂ >/dev/root / ext2 rw 0 0
ÂÂÂÂ >/proc /proc proc rw 0 0
ÂÂÂÂ >/sys /sys sysfs rw 0 0
ÂÂÂÂ >/proc/bus/usb /proc/bus/usb usbfs rw 0 0
ÂÂÂÂ >none /dev tmpfs rw 0 0
ÂÂÂÂ >devpts /dev/pts devpts rw 0 0
ÂÂÂÂ >tmpfs /dev/shm tmpfs rw 0 0
ÂÂÂÂ >none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
ÂÂÂÂ >sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0
ÂÂÂÂ >/etc/auto.misc /misc autofs rw,fd=6,pgrp=2065,timeout=300,minproto=5,maxproto=5,indirect 0 0
ÂÂÂÂ >-hosts /net autofs rw,fd=11,pgrp=2065,timeout=300,minproto=5,maxproto=5,indirect 0 0
Â
ÂÂÂÂÂ IÂmade Âthe DomU OS image by simply copying the main files from Dom0,and in Dom0 it shows it is ext3.
ÂÂÂÂÂ Whether I made the wrong way in making the image? Or thereÂare someÂother problems? I don't kown why!
ÂÂÂÂÂ Thanks all!
ÂÂÂÂÂ
