It appears that the limit I can apply is 207. After the limit is reached, the command "nfs4_setfacl -a" returned the error "Failed setxattr operation: File too large". The same problem happens if I use an ACL with more than 200 line in it. I did a little debugging session but I was not able to come up with an explanation on why I'm facing such an issue. On the other hand, I can apply hundreds of ACLs on XFS without issue. Do you know if it could be a bug with the nfs4-acl-tools package? Thank you for your support. Best, Louis de Vandi?re
