Hi,
I am 1 month old to LVM and have some basic doubts in
LVM code.
1.During initialisation y is it LVM is registered both
as a block and char device where as according to me it
is supposed to be a block device driver and when one
does the pvcreate,vgcreate..etc it calls the ioctls of
the char device of LVM.
2.what is exactly the control flow when and read/write
request is given to a file residing on the LVM
partition...(ie where and how exactly the mapping
tables exist..?)
3.what is the importance of VGDA and vgscan?
4.during boot up time what are checks/modification
made by the kernel with respect to the LVM/logical
volumes?
5.moreover to what extent is KIOBUF supported on linux
2.4. Can someone give me the workaround to check for
KIOBUF working..
thanks,
Sherlock.
