Best Ways to Move Data around to change a drive to a different format?

Featured Replies

I am in the process of trying to move my drives to ZFS however it has been a painful process as I don't have anymore slots in my server to expand. I have 13 of 18 drives as ZFS (from XFS). The remaining 5 are 2x 14TB and 3x 8TB. I have been using unbalanced but with only 19TB free it's been kind of a messy ordeal getting it to work. The process takes over a week or two to move the data off the drive, it usually fails 5-10 times throughout the process. One time I ended up duplicating a ton of data (6tbs worth) and just wondering if there is a best way to do it?

 

So I shut down all my dockers except critical ones (like Plex) so nothing is writing to my array for the time it's being done? Should I do smaller batches? Any better way to clear drives when you don't have a ton of space available to easily clear the drives too?

If you update to v7 you can use the mover to empty a disk, it should move all files in one go, as long as they are not being used or are duplicates.

Will it move the data across multiple disks? Also, is it pretty stable? I know its beta, I am not shy for trying to use betas but it also hasn't been updated since July so wasn't sure how safe it is to use.

Yes, according to the share allocation and split settings.

IMHO yes.

Is there a specific place to go to do the move/empty a drive? I didn't see anything specific in file browser or scheduler.

See the release notes, for now it's a CLI command.

cool and thank you! so, mover start -e diskN |& logger & or do I have too many "&"? where N = my disk number I need to move

 

I just want to make sure I have the logging part right to.

That's correct.

Any guesses on why it would just stop running, didn't see anything in the system log.

I just restarted it but it only moved about 300GB of 8TB before it stopped.

Did you keep the CLI window open? I don't remember if the command continues if you close it.

I wonder if there is a way to ignore a disk with the mover command? I think my issue is its loading up the cache drive, which then runs out of space. I noticed my cache drive was full last night.

maybe not actually. strike that. I think my cache was full because the mover couldn't run its task since mover was already running doing this task.

 

Still not sure. I keep the window open, its done so far:

300GB

100GB

and about 1.5TB before just "stopping."

The empty disk command won't use cache, just the other disks.
