Recreate Pool / without changing config

[Ramalama]

Hey, i have 2 Pools on PBS, one is HDD-SATA and the other is HDD-SAS.
PBS Backups already some VMs to HDD-SAS.

Can i simply temporarily move all files, simply with "rsync -avcr /HDD-SAS/* /HDD-SATA/blahbackup/" and recreate the HDD-SAS Pool? Then move the files back?

Or is there anything i need to investigate consider before?
I would simply stop the backup jobs for the time i need to recreate the pool.

What you guys think? Anyone did this already?

The reason is simply, that my SAS Drives support 512b Logical Block size and 4k...
And i want to change the SAS Drives to 4k, i forgot to do that in the first place with hdparm.
Simply to get a little more speed.

Cheers

Yes, it works.

But your command does not cover the important part. The data is under the folder .chunks. And there are the .gc-status and .lock files.
Just check with ls -la /HDD-SAS what is there.

I found another way, maybe simpler, i just added a sync job in the settings of The second pool in PBS.
And i simply sync all the backups locally from one to the other pool/storage.

It looks like its faster to me this way, instead of copying trillions of small files in the .chunks folder xD
