I've had this problem maybe two or three times in the last two months, and it is baffling me. Essentially, the system will have been up for a day or two, and the users (other than root) will have difficulty in the /usr (or other) partition. The prime symption is an error using ls in which the user is informed that permission was denied while reading .. from /usr. Initially my response was: somehow a chmod og-rx / occured, and so the user simply can't read the root, which would make sense. This wasn't the case. Then I thought perhaps the .. directory pointer in /usr had suffered the same fate, except it was also fine. Root could see the directory entry for .. fine, but normal users could not. the pwd would return a getwd error, and so on. This is not an ideal arrangement :). I shutdown this morning to single user mode, and performed: umount -a mount -a and returned to multi-user mode, and the problem still wasn't fixed. I rebooted and went into single user mode, removed the /usr mountpoint directory, and then recreated it, and went up multi-user, and it was fixed. Any advice as to what might be causing this would be much appreciated. fsck failed to show any errors on boot, so I'm really not sure where to turn next. If possible I'd like to prevent this from recurring.. Robert Watson
