RAID Expansion Not Working after new disks added

[jsnorman]

I have been trying to expand my RAID volumes, which originally were (4) Samsung 1TB disks in RAID 10. All of the RAID volume was designated for a single RAID 10 array total of approximately 1.7TB after making it RAID 10.

To get more space, I upgraded, one disk at a time, to the newer Seagate 1.5TB disks. This should have yielded an extra TB. However, the desired expansion did not occur automatically, and strangely I cannot expand using the GUI web RAID expand command. The "Disks" recognizes the full available disk space. However, under RAID->CONFIG it still says I have only 1.7TB available (100% allocated). When I try EXPAND it claims there is no space available!!

Ideas please!

Any ideas how to fix this and get my space available?

hi,

you need to do a "file system check" under "system management". the system reboots, does the file system check. after completion you need to reboot again and your space is there. you then of course have to expand the raid.
when adding larger disks, the system rebuilds them as if they had the same size. so you have to do the check manually.

Hi,

If you want to expand RAID10, you must do the follow
- remove one older HDD and insert new one, till recovery finish.
- And do up step again until change all HDD.
- When finish, you can do the expand function.

Good Lucky ;D
