Subject: How to delete/rewrite a corrupted file in a read only snapshot?
Date: Tue, 6 Feb 2024 11:12:33 -0800	[thread overview]
Message-ID: <ZcKEoftmxxp3SOiB@merlins.org> (raw)

howdy,

I'm seeing this during a background check:
[374402.156920] BTRFS warning (device dm-18): checksum error at logical 4401320624128 on dev /dev/dm-18, physical 2939697954816, root 63534, inode 595460, offset 1506283520, length 4096, links 1 (path: nobck/file2)

this is in a read only btrfs send snapshot, so I can't just delete the
file or the snspshot (I have 20 historical ones all with the same broken
fine).

can I either
1) force delete it with some admin tool
2) even better force/overwrite it with the correct file from source?

Thanks,
Marc
