Some files are not displayed when listing a directory with 'ls', but can be listed directly or accessed with 'stat' in RHEL 5 or 6

Issue

• If I run an ls on my gfs2 filesystem there is one or more files missing in the output. If I run ls against the file directly it does appear

# ls -al /mnt/lv1/data/file.txt
-rwxrwxrwx 1 60712 4064 238288 Jul  2 14:49 /mnt/lv1/data/file.txt
