Summary:	zfs send \| zfs recv not preserving ACL for some directories

Description Nathan Huff 2019-04-03 16:46:04 UTC

I have a system doing incremental replication to a second system.  It appears that zfs ACLs are not getting replicated for some directories.

On the primary system I can go into a snapshot directory and running getfacl on one of the affected directories returns ACL info.

On the second system in the snapshot directory for the replicated snapshot running getfacl on the directory returns.

# file: foo
# owner: user
# group: group
getfacl: foo: No such file or directory

filename owner and group have been obfuscated, but are correct.

It appears that the ACL data is just missing on the replicated file.  The file contents are correct.

This is not happening on all directories just some.  Not sure what the trigger is.  Let me know what other information would be useful.

zfs send using -LceI
zfs recv using -F
