RAID Migration Woes
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. |

Re: RAID Migration Woes
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 |
