Hi Team, I have an query regarding the usage of ACL on gluster volume. I have noticed that when we use normal gluster volume (without ACL) CPU load is low, but when we apply the ACL on gluster volume which internally uses Fuse ACL, CPU load gets increase about 6x times. Could you please let me know is this expected or we can do some other configuration to reduce this type of overhead on gluster volume with ACLs. For more clarification we are using kernel NFS for exporting the gluster volume. Please let me know if you require more information. -- Regards Abhishek Paliwal -------------- next part -------------- An HTML attachment was scrubbed...

There are (or at least were) certain limitations in FUSE that prevented good support for this. Please use NFS-Ganesha instead, that is the NFS server we actively develop with. Gluster/NFS is still available too, but is only receiving the occasional fixes and is only suggested for legacy users that did not move to NFS-Ganesha yet.
