gmirror magic ?

Can someone explain this to me ? I was testing gmirror/gstripe and
decided to
remove the vnode files stripe0 & stripe1. This resulted in a mirror
which kept on
working.....

 
/dev/mirror/mirro0 on /mnt (ufs, local)

DEVEL# ls /mnt/
.snap   anders  test    testje

DEVEL# ls /data/STRIPING/
create-image-file       mnt                     mnt0
mnt1

DEVEL# mdconfig -l -u md1
md1     vnode     512M  /data/STRIPING/stripe0
DEVEL# mdconfig -l -u md2
md2     vnode     512M  /data/STRIPING/stripe1
DEVEL# mdconfig -l -u md123
md123   vnode     512M  /data/STRIPING/stripe1

DEVEL# gmirror status
         Name    Status  Components
mirror/mirro0  COMPLETE  md2
                         md123

DEVEL# dd if=/dev/zero of=where-does-this-go bs=1m count=512

Does that look right to you?  You have 2 md devices using the same file?

So the files that the md devices r based on r away?
But while md still exists, the inode still exists...
So: In their directory those files r deleted, but in the file system their
inode still exists.

That is why the md devices r still there and why the gmirror can still write to
them...

RE: gmirror magic ?

Excuse my ignorance,

What I tried was removing a file on disk which 
was  attached as a "md vnode". 

I assumed removing the file on disk will "kill" 
the "md vnode" but it does not.

It seems this has nothing todo with gmirror/gstripe
but the way md vnodes work!

It's the way all files in UFS work - if it's in use, and it gets 
removed, the directory entry goes away, but the data stays there until 
all references are gone.  Once they are all gone, the data blocks get 
recycled too.

graid5 compilation problem

Hi, I  want  migrate(after two after-reboot-crashes) from gvinum to
graid5.
I take graid5 from this url:

http://home.tiscali.de/cmdr_faako/geom_raid5.tbz

and trying to compile it using this guide:
http://www.freenas.org/downloads/docs/devel-docs/#d0e689

kernel module compiles OK.
, but i meet troubles when I
trying to compile geom_raid5.c

Re[2]: graid5 compilation problem

Can you please advice how to create raid with graid5?
I found on docs
graid5 label -v -s 131072 data /dev/da0 /dev/da1 /dev/da2 /dev/da3
newfs /dev/raid5/data
mount /dev/raid5/data /mnt

So my attempt:
$ geom raid5  label -v /dev/ad4 /dev/ad6 /dev/ad8 /dev/ad10
i get:
Unknown command: label
usage: geom raid5 help
       geom raid5 list [name ...]
       geom raid5 status [-s] [name ...]
       geom raid5 load [-v]
       geom raid5 unload [-v]

Thanks!

p.s.

Looks like u do not have the user-land library installed:
% cd /usr/src/sbin/geom/class/raid5
% make && make install

Then u should have this file:
  /lib/geom/geom_raid5.so
