Hello,

 

I have an array of 8 drives, 6 of which I just finished upgrading from 8/10TB to 20TB drives. I plan on removing the remaining two 8TB drives and need to move all the data off them to the rest of the new drives.

 

Normally I would just use unbalanced without much thought, but I have hardlinks and need to make sure those are preserved.

 

What would be the best way to do this?

If you upgrade to 7.0.0-beta you can use the mover, it can now empty a disk.

I think you can use the unbalanced app and add -H to the rsync arguments in settings.

Apologies for the late reply, and thank you for yours. Just for a sanity check, would I just need to exclude the two drives from all shares and then start mover?

 

Ignore that last part, I found how to here https://docs.unraid.net/unraid-os/release-notes/7.0.0/#can-use-mover-to-empty-an-array-disk

Is there a way to do this with specific files rather than a whole disk? I am trying to consolidate commonly accessed files onto one disk to limit spin up of several disks at once.

Only manually.

Hey, were you successful in transferring the data with hard links using mover, or what was your experience?  I need to do the same.

Yep, everything transfered no problem, all hardlinks intact. One thing I will say is make sure you adjust your free space settings according to your needs before starting the transfer.

I thought mover was a terminal tool. Is it obvious where to change the free space settings?

One last question, were you on 7.0.0.beta.1 or beta.2?

You set it for a pool by clicking on the pool name on the Main tab, or for a share by clicking on the share name on the Shares tab.

Do you have to keep the terminal open while you run the mover command? 

 

I tried:

mover start -e diskN |1 logger &

But it seems that the mover stops after the webterminal tab I executed the command in terminates when my computer goes to sleep. In this case there aren't any logs indicating that the mover process stopped. 

 

Is there any way around this? I'm trying to empty a drive that is 14tb which I'd prefer to do overnight without keeping my computer on.

I believe so, but you can use, for example, the Tmux plugin.

Tmux worked perfectly. I had never used it before, but it was easy enough to figure out. Thanks for the suggestion.
