it is 46% used now. any way to reasearch when it got decreased dramatically?
and possible content that was removed?

if you have daily checkpoints, you can run nas_fs -size and look for one that drastically increased in size, that will give you an idea in what time frame that data got deleted.

Hi,

open the Celerra Monitor, and check for "Space Usage History".

found the monitor and found the date when the size has dicreased. is there a loghs on celerra that will show what has been deleted and by whom?
I guess I can open the checkpoint (previous version ) in windows and compair folder by folder but it might take forever....

Hi,

if it is a CIFS environment, you can enable audit to see the user operations, but in a NFS environment, as far as I know it's not possible, unless you use a third party tool.

if you had auditing enabled on the CIFS server ..and archived those logs often enough where they don't' get overwritten, you could have a chance to find something. There are third party products that help with capturing/reporting auditing information, search Celerra forum for "auditing"

Auditing has the followinf:
Audit system events
Audit logon events
Audit object access
Audit priviledge use
Audit process tracking
Audit policy change
Audit account management
Audit directory service access
Audit account logon events

which one will tell me if anyfiles/folders were deleted?

I have tried open the file and I see the event. But when I delete the file it does not audit that

OK. looks like it is not human readable when it comes to deleting the object

Open file

Object Open:
Object Server: Security Account Manager
Object Type: SAM_SERVER
Object Name: LAFILE
New Handle ID: 0072f629
Operation ID: {open}
Delete file:

Object Open:
Object Server: Security Account Manager
Object Type: SAM_SERVER
Object Name: LAFILE
New Handle ID: 0072f629
Operation ID: {6c047349,446c6c04}

This ID 446c6c04 is identical when deleting files.
Is it by design or cosmetic bug?
