Hi,
I have a TS419+ NAS in RAID 5 with 4 x 3 TB drives.
I had 3x3 TB drives in RAID 5 and used the "Add drive" option as suggested in the QNAP documention.
31 hours later the NAS sees disk 4 as part of the RAID 5 array but my total storage is still the same amount it was as with 3 drives. Log files say "RAID Rebuild successful" and no errors.
Any ideas? Or will i now have to recreate the array from scratch?
Thanks

Re: Add drive to RAID 5 succeeded but no extra capacity
Maybe the device has added the additional drive as a spare drive instead of a live drive and you need to expand the capacity to all 4disks?
Do you have an option under "Disk Management" -> Raid Management -> Expand capactiy?
However in the manual they say the "Add hard drive" option should be sufficient.
Disclaimer: before you try to expand the array, backup all data!

Re: Add drive to RAID 5 succeeded but no extra capacity
Thanks for that.. I could have sworn that it wasn't active.
Anyway, it was active, I tried it but got a "Raid 5 Expansion Failed".
Nevermind, there's only about 600GB on it (after it deleted all 3TB of my data doing a Raid 1 to Raid 5 migration, exactly as the instructions said to) so i just copied it all to my 2TB linkstation, reset the 419P+ and started again.
2 processes in a row this thing has messed up lol, but also my fault that i didn't back up, nothing important lost admittedly lol.
Lesson learnt.
Thanks for your post

Re: Add drive to RAID 5 succeeded but no extra capacity
Hey all. I've got the same problem. I know that I added the drive. The logs confirm it.
I have a TS419+ NAS in RAID 5 with 4 x 2 TB drives.
I had 3x2 TB drives in RAID 5 and used the "Add drive" option as suggested in the QNAP documention.
31 hours later the NAS sees disk 4 as part of the RAID 5 array but my total storage is still the same amount it was as with 3 drives. Log files say "RAID Rebuild successful" and no errors.
2012-05-21 05:51:22 System 127.0.0.1 localhost [RAID5 Disk Volume: Drive 1 2 3 4] Expanding Raid Device failed.
2012-05-21 05:43:05 System 127.0.0.1 localhost [RAID5 Disk Volume: Drive 1 2 3 4] Rebuilding completed.
2012-05-19 09:18:09 System 127.0.0.1 localhost [RAID5 Disk Volume: Drive 1 2 3 4] Start rebuilding.
2012-05-19 09:18:05 System 127.0.0.1 localhost [RAID5 Disk Volume: Drive 1 2 3] Start to expand Raid Device: Add Drive 4.
How can I correct this problem?

Did you follow the instructions provided in the QNAP FAQ: Online RAID Capacity Expansion & RAID Level Migration?chopshop007 wrote:Hey all. I've got the same problem. I know that I added the drive. The logs confirm it.

As the drive seems to have failed, you might want to temporarily put the drive in a PC, so you can throughly test it before trying again.

Re: Add drive to RAID 5 succeeded but no extra capacity
Any services, applications or QPKGs active preventing the necessary unmount/mount of the disk volume?
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!
A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.
All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

Re: Add drive to RAID 5 succeeded but no extra capacity
That was the magic bullet. I had to log in through SSH and kill off a the iscsi process to get it to properly umount. Even when they were turned off still some system processes were not exiting.P3R wrote:Any services, applications or QPKGs active preventing the necessary unmount/mount of the disk volume?
