Re: Added 3rd drive to Ultra 6...same volume size?

DrJones · ‎2012-11-20

Hi.

I have an Ultra 6 with 2x2TB seagate drives. I purchased a third 2tb drive (identical model to the other two) to increase our storage capacity.

The NAS sees the drive, worked on it for a while.....and still shows the exact same space as before, only with three drives instead of two.

What did I do wrong, and how can I expand the volume? I believe the NAS must have somehow used this disk for dual-redundancy, which I do not want since this NAS acts as a backup for the server on-site. I want to increase the volume size.

Please help.

Thanks!

Perhaps you did not wait long enough (the size is expanded after the disks are restriped). If you are sure that it is finished, try restarting the NAS.

DrJones · ‎2012-11-20

Well I put it in around 11AM Friday, just rebooted it last night. That's about 72 hours to re-stripe. Isn't that enough? What do I do now?

DrJones · ‎2012-11-20

When I logon to frontview / volumes/volume settings, it shows all three disks, then there's an option that says "next added drive:" and the "Will be used to expand volume" setting is selected. I hit "apply" and....nothing.

I'm looking at frontview on a different Ultra 6, and it doesn't have that option, presumably because I haven't recently added a third drive. The last time I did, I believe it popped up & asked me what I wanted to do; expand the volume or add dual redundancy. I did not get any such option on this NAS.

Any ideas?

Try restarting it again, if that doesn't work submit an on-line support ticket.

You need 4 drives to get dual redundancy, so any setting you applied there is for the next disk, not the three you have installed.

'Should I pull the drive out & re-insert it maybe?

StephenB · ‎2012-11-20

Try the restart first, there are other posts here indicating that multiple restarts are sometimes needed. If you pull/reinsert the drive, Frontview will probably treat it as a new drive.

Does the Frontview "volume settings" page say the volume is redundant? Also, does it show same space allocated (e.g. "xxxx GB allocated" on all three drives?

DrJones · ‎2012-11-20

I restarted like three times, makes no difference whatsoever. Yes frontview says its redundant and exact same space allocated on each drive.

Ok, then. There's some steps in these two links: http://home.bott.ca/webserver/?p=550 and viewtopic.php?f=66&t=42113

If they don't help (or don't apply), then submit an on-line support ticket.

DrJones · ‎2012-11-21

Thank you so much for your help....I will try the steps outlined in those posts & report back soon.

What is the displayed volume size?
What is the displayed size of each disk?
What does your log say about initialisation and resync of the new disk?
If the volume is still around 2tb, then I would suggest that the new disk is probably faulty

I'd like to admit that I'm on RAIDiator 4.2.19, which is not the latest. I'm afraid to upgrade because we're using Replicate on this NAS & it's working perfectly.

Additionally, I cannot find any setting in Frontview for snapshots - it absolutely does not exist.

Thank you guys for the help.

I have had a similar issue happen on a NAS - the drive I added was not an advanced format drive, and the model number was identical to the other drives which were all advanced format. I replaced the drive with an advanced format drive and all was well.

vandermerwe · ‎2012-11-22

Have you tried the suggestions in the links StephenB provided?
If you have then either contact support or if you have a current backup you could try hot removing the new disk and replacing it. There is a risk to data though.

What is an "advanced format" drive? Never heard that term.

All, looks like I will need to open a support ticket as I've tried the steps outlined in those two threads multiple times and still no luck...

http://en.wikipedia.org/wiki/Advanced_Format

All new drives are "Advanced format" - manufacturers agreed to phase out the older format in 2011.
