I have SunOS 5.8.

Yesterday when i tried to log in I got message:
Could not chdir to home directory /export/home/blahblah: No such file or directory

Instead of the home directory i used to get in, I was bounced to the root directory. I searched through the filesystems but could not find my home directory

Since we don't have admin for this machine, no one know what happened

What could be the cause? Anyway to diagnose it and how do i fix it?

Any suggestion would be greatly appreciated

Check /etc/vfstab - see if there is a mount point that overlays /export or /export/home. See if that is mounted (df -k /export or df -k /export/home). If it crashed or got dismounted, then it would look like your home directory was gone (which it would be ). Try to fsck the device (/dev/rdsk/something) and then try mounting it to the appropriate mount point.

y must you go through such hard process? maybe the dir itself does not exists? a good practise is to specify the home dir during a/c creation using useradd cmd with -d option
