With the default settings of vfs_acl_xattr samba takes posix acls into
account when delivering data - how can I activate
"acl_xattr:ignore system acls = yes"
without loosing the information saved in posix acls? Background: our
future file system won't be able to support acls.
Is there a way to migrate all acl information from the posix acls into
the extended attributes? I have an inkling that I read at some stage,
that vfs_acl_xattr deletes/overwrites the extended attributes once the
posix acls are changed. Is there a way to trigger that on cli?
The idea is to change these settings on the old server before copying
the data to the new server. I hope to be able to use rsync for the
Thanks you for any help with this!
