Extend disk in Ms Cluster with exchange 2003 |
|
|
Hi.
I have a big problem just now:
We have a San from IBM FastT900 and i needed to extend one of my storage
groups in the exchange cluster.
First i extended the Lun on the san=Ok
Then i run a Ibm specific command line tools for hootadd the extended disk
area=Ok
After that I run diskpart against volume i wanted to extend=Ok
Atfer that i run diskmanager and that tells me i have succesfully extended
the disk.
But when i browse my comtuer it still list the old diskspace?????
I Have tried to restart the Node but get the same result.
If i stopp the cluster service then the system list the disk space ok but as
soon i
start the cluster service it list the old configuration again.
Is it possible to have the cluster to rescan the disk? I Found a article
that applys to this problem but for Nt4 Cluster.
I run Windows 2003 Enterprise Ed with Exchnage 2003 Enterprise ed on it.
Please can someone help me out with this?

Hi Rodney.
Thanks for answering me:
I read in the newsgroup a answer from "Joe" a similar case and i think I´m
the unlucky 5% he´s talking about. Lokk down here in my answer to you.
Do you know something about the utility to workaround my problem?
He says that microsoft has a utility to fix this problem.
In my case diskmanager looks ok but if i browse my computer the old disksize
is still there, if i stopp cluster service everthinh is ok and when i start
again the old disksize is back. Looks like Microsoft has a non public fix
for this if Joe know what he´s talking about.?
Regards
Micael

You should not take the quorum disk offline. You should not have the =
MSDTC
online while you're extending this disk...assuming your MSDTC =
resource is
using the quorum disk for storage. If not, then it is irrevelant. =
You really
shouldn't need to extend the quorum drive, but if you do need to =
extend the
disk where the quorum resides, uses MSCS to move the quorum log to a
different disk while you extend the quorum's old drive. The key is =
that you
do not want any open "handles" on the disk while you're extending =
the file
system.
=20
You should only extend one disk at a time, so you shouldn't need to =
take all
resources offline. Only take the resources in that disk's group =
offline and
that should kill most of the handles on the disk. You might consider =
using
the handle.exe tool from www.sysinternals.com as well to verify =
there are no
handles on the disk when you extend.
=20
I have used diskpart and 95% of the time (with W2K SP4 or 2003) it =

great. Even if you're one of the unlucky 5%, you will NOT lose data =

extending the file system. You may not have access to the extra =
freespace,
but you will not lose data. In the situations where I've seen =
diskpart fail
to extend the filesystem (even though disk manager thinks it did), =
Microsoft
can help you fix the issue as they have a utility to correct this.

The utility is called fsextend. Not sure if there's a public version
available...so you're better off calling MSFT.
