Implementing checksums in XFS
Quoted 6 lines · Yannis Klonatos
Hi all,
I would like to ask whether, since implementing checksums
seams to be the current trend for file-systems
(e.g. EXT4, BTRFS), anyone is planning on providing such functionality for XFS also.
Yes, it's work in progress that has been stalled a little. See:

Oh that would be very welcome. A "secure" filesystem sounds really good, especially if it's fast as XFS is :-)
I'd implement it everywhere immediately as soon as it's available. Will existing XFS's be upgradeable in some way other that backup/restore?

checksumming inodes and btree nodes means larger data structures for those, so no there's no upgrade path available.
