I have the following problem.

Initially I have created a RAID5 with 3 disks. I have no problems using this configuration. However after I migrated the RAID5 to 5 disks, the extra storage is not available.
"setup->disk manager" is showing the correct size but "status->share volume" is showing the old size;

Function: Share volume statistics

Total volume size (GB): 595.9
Used volume size (GB): 0.1
Free volume size (GB): 595.8
Reserved for snapshot (GB): 0

Volume usage: 0%



I have downloaded the logs and the file tests.log shows this;

*-----------------------------------------------------------------------------*
fdisk -l
*-----------------------------------------------------------------------------*

Disk /dev/sda doesn't contain a valid partition table

Disk /dev/sda: 1279.9 GB, 1279954780160 bytes
255 heads, 63 sectors/track, 155612 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes


I tried "repair filesystem on LV" with the extended console tools which doesn't help.
Currently I'm in a test fase, so no production data is stored on the NAS. I think by "deleting content of units" with the extended console tools and then using "setup->disk manager" I will get the full capacity.
However this is for me not an ideal solution because during the migration to the NAS I want to migrate the RAID5 from 5 disks to 8 disks without loosing data.
