ZFS Rewrite - Resumable rewrite

Just wanting to share my resumable ZFS rewrite

I had my ZFS REWRITE stop/pause while two programs where trying to access the same block of data (I believe thats what it was at least), and at that point i was over 24 hours in.

Instead of restarting the full zfs rewrite I wanted to just resume, this wrapper uses the same traversal method as the original zfs rewrite method so it should resume ok.

Tom Lawrence just posted a video on this. The current version to Truenas 25.10.01 does not support resume, you have to start over.

After your made your account you should have received a DM from a bot - after completing the tutorial in that DM you’ll be allowed to post links/pictures if I’m not mistaken.

Simple and useful.

Tom’s video was what reminded me to upload the resumable zfs, i checked it against the source code and last 1000 files with a dry run to confirm traverse was the exact same

Thanks, it looks like I just got the permission to post links, maybe I just needed a few posts
