Hi, all:
At first I have an idea to improve the performance of the log mechanism in
ext3 file system of DomU, but when I do some experiment in DomU, I find a
strange thing.
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.
# df -lhT
>Filesystem Type Size Used Avail Use% Mounted on
>/dev/sda1 ext3 9.2G 3.7G 5.1G 42% /
>tmpfs tmpfs 129M 0 129M 0% /dev/shm
# cat /proc/mounts
>rootfs / rootfs rw 0 0
>/dev/root / ext2 rw 0 0
>/proc /proc proc rw 0 0
>/sys /sys sysfs rw 0 0
>/proc/bus/usb /proc/bus/usb usbfs rw 0 0
>none /dev tmpfs rw 0 0
>devpts /dev/pts devpts rw 0 0
>tmpfs /dev/shm tmpfs rw 0 0
>none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
>sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0
>/etc/auto.misc /misc autofs
rw,fd=6,pgrp=2065,timeout=300,minproto=5,maxproto=5,indirect 0 0
>-hosts /net autofs
rw,fd=11,pgrp=2065,timeout=300,minproto=5,maxproto=5,indirect 0 0
I made the DomU OS image by simply copying the main files from Dom0,and
in Dom0 it shows it is ext3.
Whether I made the wrong way in making the image? Or there are some other
problems? I don't kown why!
Thanks all!

Re: [Xen-devel] The file system type of DomU is ext2 or ext3?
What are the contents of the DomU''s /etc/fstab? One thing to check is the type of the root file system in that file. 2009/12/21 Ye Zhou <zhouyejoe@hotmail.com>> Hi, all: > At first I have an idea to improve the performance of the log > mechanism in ext3 file system of DomU, but when I do some experiment in > DomU, I find a strange thing. > When I input command "df -lhT" to see the file system type, it shows > that it is ext3.
