Adaptec 2810SA added new drive, now what? |
|
|
I just added a new 250G drive to a 3-drive raid 5 system (making 4
drives now) and although the Adaptec Storage Manager shows all 4 drives
as being part of my raid 5 (TomRaid), the extra space does not show up
in My Computer and it shows as an unused volume in Disk Manager. What
do I have to do in order to make Windows see it as part of the capacity
of my raid array? |

Use the DISKPART command-line utility (XP and 2003 itīs integrated in the
basic-OS, under 2000 and NT itīs part of the resource kit) and EXTEND the
volume. Will only work if itīs a basic disk and primary partition. No
dynamic disks and no extended partitions/logical drives.
Read the documentation beforehand and - as always - have a good backup of
your data.

Thanks for the response, Michael.
I don't understand some of the terms used like "basic disk" and
"dynamic disk". Can you elaborate?
Thanks.

Right-click on My Computer --> Manage --> Disk Management. On the left side
where you see your disks (Disk 0, Disk 1...) On the label is either "Basic"
or "Dynamic". If the disk is "dynamic" the extension process will not work,
if itīs basic no problem. For the difference between basic and dynamic disks
have a look into the help and support center of your windows system. Itīs
quite elaborative on the subject :-)
One additional free advice: If you donīt know exactly what youīre doing.
Donīt do it! Managing disks is potentially very very disruptive and can lead
to unrecoverable data loss.

"Basic Disk" - usual partitioned disk with MBR.
"Dynamic Disk" - disk partitioned with Veritas's "dmio" (which MS has OEMed),
which has a LDM database.
w2k and later support software RAIDs only on Dynamic Disks.

I checked the disk and it is indeed "basic". Here are the steps that
I'm performing in DISKPART only to receive
"DiskPart failed to extend the volume.
Please make sure the volume is valid for extending."
Here is the sequence of DISKPART commands I used:

Noted. I'm building this on a home system that I'm putting together.
If any data loss occurs, not biggy. |

After the "list disk" it shows that thereīs no free space available
Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
Disk 0 Online 6189 MB 0 B (!!!!!!!!!!)
Disk 1 Online 698 GB 0 B (!!!!!!!!!!)
So thereīs no way to extend the partition.
Where the "0 B" stands there should be the free space of your extended
RAID-Volume. Since thereīs no free space, what should DISKPART extend or
more precisely, where should DISKPART extend.
You need to have free space available in order to extend the partition.
Why thereīs no free space? I have no idea. In your original post you
wrote itīs shown in DiskManager as a NEW volume. This might indicate,
that you created a seperate RAID volume and did NOT extend the existing
RAID 5.
Since Iīm not at the machine nor can have a look at it, everything that
comes now is a wild ass guess:
Delete the new RAID Volume. If you delete the existing one, your data is
lost. Everything. But from here it looks like you created another
RAID volume which should have no data since it doesnīt show with a drive
letter, hence no chance of containing data up till now.
After EXTENDING/GROWING (different manufactureres of RAID Controllers
use different terminology) the RAID Volume, you should see the free
space DIRECTLY after the existing partition with a drive letter in
DiskManager and NOT as a seperate volume. EXTENDING/GROWING a RAID
5-Volume is often a lengthy process, lasting from mere minutes to
sometimes hours depending on the RAID controller model.
Note: You can only extend a partition with DISKPART if the free space
(usually marked in black while the existing partition is of a bluish
color) is DIRECTLY after the existing partition. Or in other words: Only
the primary partition thatīs directly followed by free space is extensible.

O.K., this makes things a bit easier... :-)

If it helps, this below is from the Adaptec help system:-
Quote.
1.. You cannot extend the following types of volumes:
a.. Striped
b.. Mirrored
c.. RAID level-5
d.. FAT or FAT32 format
e.. System
f.. Startup (boot)
g.. Simple or extended volumes that were upgraded from basic to
dynamic.
2.. You can extend a volume only if the volume is formatted using NTFS
or does not contain a file system.
3.. You can extend a simple or extended volume only if the volume was
created as a dynamic volume.
4.. You can extend a simple volume if the extension will occur within
its original physical drive or onto additional physical drives.
5.. After a volume is extended onto multiple drives (spanned), it cannot
be mirrored or striped.
6.. You can extend simple and spanned volumes on dynamic disks onto a
maximum of 32 dynamic disks.
7.. After a spanned volume is extended, you cannot delete any portion of
the volume without deleting the entire spanned volume.

Start/Run/diskmgmt.msc
This is the GUI version of DISKPART. Can it help?

I saw all that stuff in the help file but didn't think I understood it.
I still don't think I understand it because although it said that I
couldn't extent a Raid 5, I was able to through windows.
I just had to turn the Raid array "disk 1" in to a dynamic disk. Then
I was able to extend the pre-existing raid volume with the new volume
to get the full disk size I was expecting.
This was done with XP. |
