.snapshot causing problems?

If you see

# du -hs /some/nfs/mount
 
du: WARNING: Circular directory structure.
This almost certainly means that you have a corrupted file system.
NOTIFY YOUR SYSTEM MANAGER.
The following directory is part of the cycle:
  `/some/nfs/mount/.snapshot/v_nightly.8'

disable snapshot directory from being visible on the volume

$ vol options some_volume nosnapdir on

Replacing a disk

This has been tested on a FAS960 running Release 6.5.2R1P17

Procedure

1. telnet to filer
2. priv set advanced 1 blink_on 2a.16
3. remove drive with blinking LED 1 replace failed drive with new drive
4. run: sysconfig -r to ensure that the drive has been removed as failed and new drive has been recognized.
5. blink_off 2a.16
6. priv set

Verification

Just run the following command that the new drive is recognized by the system.

sysconfig -r

If you do not see the drive, contact NetApp
