Sorry, but i can't found any info about operating on already mounted
disk. As i known, libguestfs allows operating inside virtual machine via
userspace daemon. But in my case this works inside kernel module. But if
fs is using it partition table not able to altered because bdev is
busy. Fdisk allows to change partition table, but says, that kernel must
be rebooted to see any changes. I think, that if i can after fdisk
change inside kernel some info about partitions i can do online resizing
fs (ext3). But i see, that partitions is only be operated by ioctl....
If some body says me what functions inside kernel may be exported (says
export_symbol_gpl) to change part info, i'm very glad =)
