Reflinks and Deduplication

Is it safe to use this now?

Doesn't look very safe:
XFS (loop0): EXPERIMENTAL reflink feature enabled. Use at your own risk!
That doesn't prevent adding instructions for this feature to the article. -- nl6720 (talk) 13:32, 16 November 2017 (UTC)
See this thread, it gives an overview what needs to be done: https://www.spinics.net/lists/linux-xfs/msg09845.html Patrakov (talk) 08:55, 17 December 2017 (UTC)
It's marked stable as of kernel 4.16. Remove EXPERIMENTAL tags for reflink and rmapbt Ozz (talk) 12:06, 10 June 2018 (UTC)

Enable hardware accelerated CRC32C?

See Ext4#Enabling metadata checksums. Does the same apply to XFS?

AFAIK the issue with ext4 is that it doesn't list the crc32c module as a dependency, which means that it needs to be loaded manually. xfs has an explicit dependency on libcrc32c module (which has a soft dependency on crc32c) so manual module loading should not be required. -- nl6720 (talk) 10:07, 25 March 2018 (UTC)
