That is ISFS, not WFS. (Internal Storage File System). It is the file system that this thread is about, and it is totally not GFS2...00:00:05:084: ISFS: fs_ops.c(3733)Can not change the owner Id of a non-empty file
00:00:05:084: ISFS: fs_ops.c(6719)Could not set attribute, rc=-524312
It was on a log actually. fs_ops.c, the only google result related to that is GFS2.
