[SOLVED] Parity and BTRFS Snapshots

Featured Replies

Hi,

I have a question concerning parity and BTRFS snapshots. 
Let’s say all my data disks are BTRFS, and I snapshotted every single one. Now suppose something catastrophic happened and I need to rollback the snapshot on all the disks. Wouldn’t the parity be out of sync and if so, how would I fix that?

 

Thank you so much!

Parity is unaware of file systems - it is merely working at the bit level on drive sectors.    It is therefore completely unaware of the fact that there are snapshots being used - as far as parity is concerned they are just bit patterns.  Anytime you do anything that causes a write to happen to any drive then parity is updated accordingly.

Ok so that means that it shouldn't affect parity at all since it's just in the filesystem right? It's just as if you deleted a bunch of files and created new ones.

 

Thank you!

Yes, any filesystem operation will update parity.
