Bug ID: 203303
Summary: ISSUE with md vnode device with size mismatch
Product: Base System
Version: 10.2-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: roberf...@gmail.com
We create a 32M file using on a ufs filesystem:
dd if=/dev/random of=/tmp/test.file bs=32M count=1
Once a md device is created using the following command:
mdconfig -at vnode -f /tmp/test.file -s 64M
then, we try to execute the next command:
dd if=/dev/md0 of=cpy_test.file bs=16M
We get a file that is 64M long. We expected some error after 32M, but the
operation succeed.
The exceeding 32M of cpy_test.file is the last 16M of the original file
repeated twice.
More interesting, when we use newfs on the md0 device:
newfs /dev/md0
we get that the file "/tmp/test.file" under md0 becomes automatically 64M
large.
