How to resolve not readable files
I am not sure how this started, but I assume I clicked some option on FreeNAS that set the ACL flag. Then I migrated to FreeBSD.
Unfortunately I set this flag on only a few directories and since I also had a hardware problem I didn’t notice right away or correlate it with other actions.
When I did discover it I was setting up a new NFS client to my NAS and thought it was an NFS issue.
Setting the ZFS ACL flag results in allowing you to create a file yet not being able to read it.
$ ls -l
---------- 1 jjf jjf 0 Nov 29 14:25 t
One way to tell if you have an ACL set is by the plus sign after the permissions.
drwxrwxr-x+ 14 jjf jjf 15 Nov 28 05:21 music
By running the following command you can recursively clear all ACLs that you may have set.
setfacl -Rb *
