ChrisYx511 Posted November 18, 2020 Share Posted November 18, 2020 (edited) 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! Edited January 21, 2021 by ChrisYx511 Marked as solved Quote Link to comment
itimpi Posted November 18, 2020 Share Posted November 18, 2020 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. 1 Quote Link to comment
ChrisYx511 Posted November 18, 2020 Author Share Posted November 18, 2020 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! Quote Link to comment
JorgeB Posted November 18, 2020 Share Posted November 18, 2020 Yes, any filesystem operation will update parity. Quote Link to comment
