It isn't. This one is supposed to fix an issue which is unrelated to block cloning (but can be amplified by block cloning). This issue is fixed since some weeks, your Dec 23 build should not need it (when the issues happens, you have files with zero as parts of the data instead of the real data, and only if you copy files at the same time as those files are modified, and then only if you happen to get the timing right). The sysctl for block cloning is vfs.zfs.bclone_enabled. To check if a pool has made use of block cloning: zpool get all poolname | grep bclone Bye, Alexander. -- http://www.Leidinger.net Alexander@Leidinger.net: PGP 0x8F31830F9F2772BF http://www.FreeBSD.org netchild@FreeBSD.org : PGP 0x8F31830F9F2772BF --=_9361e29c39098c5b19f86bb32c7ffe37 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc; size=833 Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEER9UlYXp1PSd08nWXEg2wmwP42IYFAmWTu0EACgkQEg2wmwP4 2IajCQ//QbH+PlqywDSbQHnUaZjl9GsuxsgppKzQNGv7mWgomDB+lSlfR0KZMdDz dSWh5UtUkDl2x1ZQPQUTNWo/HC4F9b7n6EMdI/2N2vanptnaWq49+UZ2a2bNUfs5 q7ocNODRXQbcf/O8wfcFo+6rJhogXNv8gURfZQkjc7lh+inzB7iNc9uXzIR0TPex PKadi6CtWYV0LGromJZ8ZPxJXXzqMTaKoPBtkzIjDhQ9opJzNBRgViqXaoWjkNJi aYxgqQOYPC7oAIcMO5/IM6LfNrDdiFAnE6OkeCHTRgTxTlnosMsjQNES86UeEkNA V5RZVb0ghbSVinWgHNHOu4gFrJIAIxRW4OnUA+yaVJ+T/mAjLOQcVS20Z0GK9QW5 giw24+lXQZCG/G5INZgTe3IfpG7uIRUyJDpuVQrangE1u31xJB+X071SQAeSvrOp cn3PrQsDRNtnqE636Y3g+eU697+u7+N3MVYsdLaBmnoXAXqPzHPNU2HkbCo8ZpQE 9PodopAoHt2SxvLxx+0GN1TRPgfyS6L5dB2LNoPhzi5Ve7TgjiZPdyVWnz/JeEwp REdFvQtUKqnIp6WQP29gA6O0EwULqef5HgszX4g9x3ujAB+I8+FX55XiLGTYwZnm LplwKs7GzEzcxcJfiTEfXPJI1sf6zIU8XjuIKFUArAEkAN7MR6w= =9Xnj -----END PGP SIGNATURE----- --=_9361e29c39098c5b19f86bb32c7ffe37--
