btrfs under xen domU

btrfs under xen domU

[Vasiliy G Tolstov]

Hello. I want to use btrfs on root fs under xen domU.

Fs can grow in dom0 by dd if=/dev/zero of=image.img bs=1M count=0
seek=xxxx

I want to grow fs under domU after that automatically. Can i do mount -o
remount,rw,maxsize / on already mounted root fs with rw ?

Thank You for answer.

As far as i know, Xen won't update the size of block device until the D=
omU has=20
been restarted. After that "mount -o rw,maxsize /" should work as adver=
tised.
