I am using an AIX system. The directory I am using is on GPFS(Type mmfs in mount command) [Not NFS]. What I am seeing is time to time the ownership is changing to nobody. I was wondering if someone can help me understand what activity can change the directory ownership to nobody. I am not expecting the root user to run chown specifically. What else could trigger this change of ownership. Following is some of the directory and file system listing -
$ ls -ld /x/y/z
drwxr-xr-x 165 nobody app_dev 65536 Jan 31 19:41 /x/y/z
$
$ df -g /x/y/z
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/gpfsfl 654865.87 46975.80 93% 35495352 97% /x/y
$
$ ls -ld /x/y
drwxrwxr-x 172 app app_dev 65536 Jan 14 15:32 /x/y
$
