NFS access denied. File and group owner are inconsistent. Description: NFS Access Denied: both file owner and group owner must be from the same identity type (NTFS vs UNIX), attempt to set different identity types was detected. Client {{clientIpAddr}} User: {{nfsUserName}}, file {{dsidPath}} on NAS Volume {{nasContainerIdIntegerName}}, setting ownership: {{userOwnerName}} ({{userIdentityType}}) : {{groupOwnerName}} ({{groupIdentityType}}). Action Items: It is impossible to change file owner id to UID if the original file ownership is SID/GSID. If the user wants to change the ownership of the file to UNIX ownership, he must set UID and GID at same time. For example: user chown michael:group and not chown michael.
