RAID Migration Woes

[tinroof]

Hi all,

Hope someone can help me with this problem.

I have a N5200BR which had 5 x 320GB HDD arrange in RAID 5.

Recently I purchase 5 new 750GB disk to increase capaciity and went through the long process of swapping out the drives one by one. This process went well.

I clicked expand the array and was given the option to expand the array by x%, from which I chose 58% (ie use all free space). Now this took all of a about 10 seconds! A quick check of the Logs shows

2008/05/27 08:33:08 N5200BR : Expansion Start [ RAID ] [ RAID5 ].
2008/05/27 08:33:14 N5200BR : [Expansion Fail] LVM-lv stop fail ...
2008/05/27 08:33:14 N5200BR : [Expansion Fail] Resize file system fail ...
2008/05/27 08:33:14 N5200BR : [Expansion Fail] Umount data volume fail ...
2008/05/27 08:33:15 N5200BR : [Expansion Fail] Mount data volume fail ...
008/05/27 08:33:15 N5200BR RAID resize successfully.
2008/05/27 08:33:19 N5200BR : Expansion End [ RAID ] [ RAID5 ].

Now, the RAID information shows

RAID Status Used Disks Total Data
Level Disks Capacity Capacity

5 Healthy 1,2,3,4,5 2787 GB 855.5 GB / 1139.3 GB

And the pie chart show 100% used. WTF? Where's the 1.6TB of storage gone?

Any ideas how to fix this?

I am on FW 2.0.0.8 BTW.

Hi,

Too bad no real solution for this one, as I have got the same thing (only on a Thecus 1u4500 unit).
Here is what I did:
1. migrated from 2 disks(750GB) RAID-1 to 4 disks(750GB) RAID-5 (on firmware 2.0.0.1)
2. there was the space problems (not growing), so I upgraded to firmware 2.0.0.4
3. selected Expand RAID
4. got the same errors as tinroof
5. now I can no longer write to the thecus unit saying not enough disk space.

Is there any chance I can recover from this?

Thanks

I am having the same issue.

I submitted a ticket (YVU-298723).

Who ever responded did not read my ticket properly. He advised me to do a migration not an expand when I add a drive.

Obvisouly I had already said in my ticket that I had already done the migration and was now doing the expand to use all the new space.

Yvon, could you get someone to look into this for me?
