I can not create an ACL with more than 25 entries (users).
Windows share:
I go to the security tab and add 20 users there - no problem.
If I add 5 more users, I get the next error:
"Unable to save permission changes on test.txt" "Access is denied"
UNIX NFS share:
I use setfacl. With 20 entries (users) setfacl works without any problem.
But if ACL has more than 25 entries (users) it gives the next message:
"failed to set acl entries" "setacl error: Invalid argument"
What can be done about that?
Check the log files for any errors, also check to see if you are listed in the CONFIGURATION -> NAS settings -> Function: SMB settings and check the ACL Groups.
I've found this article on Internet about it: http://www.suse.de/~agruen/acl/linux-acls/online/
I'll see what I can do about it.Quote:
Most UNIX-like systems that support ACLs limit the number of ACL entries allowed to some reasonable number. Table 3 shows the limits on Linux.
Table: Maximum Number of Supported ACL Entries File system Max. entries
XFS 25
Ext2, Ext3 32
ReiserFS, JFS 8191
ACLs with a high number of ACL entries tend to become more difficult to manage. More than a handful of ACL entries are usually an indication of bad application design. In most such cases, it makes more sense to make better use of groups instead of bloating ACLs.
Yes, this is the issue with XFS only allowing 25 entries. We can not fix this. Best to manage with groups. Any more then the 25 could cause performance issues taking it's time to accommodate the ACL.
