Hi all,
I had a perfectly working unraid NAS but ran into the need to upgrade storage capacity. I purchased two new 10TB iron wolf drives and installed them.

I wanted 10TB parity, 10TB Disk and the SSD drives would be the cache.

I had an impossible time trying to make one of the 10TB drives the parity drive, and one of the new drives has errors.

I don't know what I'm doing, very confused. I attached the tower diagnostics and the smart test results. I gave up trying to fix it because I have a lot of work to do. I thought the last thing to try was some forum help.

- Is it okay to just leave the NAS with no parity drive?
- Should I just leave it and wait till there are 24TB disks, and then buy one and use that as parity?
- Should I use crashplan as by backup and redundancy solution until 24+ TB become available?
- Is there an easy way to reconfigure my NAS without loosing my data.

Any help would be greatly appreciated.
Steve

Diags are after rebooting so we cannot see what happened, try to add parity again and post new diags after any errors.

Hi,
I tried to remove the two 10TB drives, but I cant start the server. When I remove them, it says, wrong disks.

I'm very afraid of making a new config because I don't want to loose my data.

The data is on the two Samsung 2TB drives. I don't want to loose it. I simply don't understand how to move things around and I fear loosing my important data.

I want 10TB to be parity and 10TB to be disk and the SSDs to be cache. But I don't know how to move it around without losing data.

If you want to remove disks from the array you need to do a new config, doing that doesn't touch the data in the assigned data devices.

Thanks for helping me,
I made a new config, I set the 10TB drive to parity and the other 10TB drive to disk.

I left all the other drives out, because I want to protect the data on them.

If I move the other SSD drives with the data on them to the cache pool, will I loose the data on them?

If I move the other SSD drives with the data on them, and the data is preserved, will that data be moved to the parity and disk drives?

Should I mount the unassigned drives and then use the unbalance app to move the data to the disk?

Thank you.

Another issue Im having is that one of my 10TB disks has a file system error.

Parity ST10000NT001-3LY101_WP00XSQR - 10 TB (sde)

 

does anyone know the best way to rebuild the file system for a disk?

You need to create a new single device pool for each device, so two separate pools, and they must be new pools.

That's not a filesystem error, it's a bad disk that should be replaced.

I purchased those two disks thinking they were new. They were advertised as new but came to me in a generic postage box, inside the two drives were enclosed in static bags. I think they must be advertising them as new but they must be used.

I contacted the seller and will send them back. I will purchase new ones from a different store in person tomorrow.

I can see all my data is still there by following your advice to add the SSD disks to respective cache pools.

Thanks so much for helping me out. Unraid seems pretty damn robust.
