Extend / Resize Snapmirror Volume

FAS20xx in source , to a FAS20xx in Destination

1) Break the mirror on FAS20xx in destination
2) Resize the volume of FAS20xx in source
3) Resize the FAS20xx in destination backup Volume with same size of volume FAS20xx in source primary volume
    (You can keep the destination much higher in space.)



5) Initialize the snapmirror on FAS20xx in destination


 If you get  Volume has a fixed filesystem size (fs_size_fixed) error while you are trying to resize volume. You should turn fixed file system option off.

1)Execute df -h on console to see all volumes.

2) vol options volume fs_size_fixed off

SnapVault Flex Clone Read/writeable clone

When creating a flex clone with Qtree SnapMirror (QSM) (SnapVault destination volume) based on a snapshot newer than the base snapshot for the QSM/SnapVault relationship;the qtree will be cloned in RO mode.

Below is an example of what was encountered:

filer1*> snapvault status /vol/HSQLdst/data

Snapvault secondary is ON.

Source                Destination               State          Lag        Status

filer2:/vol/HSQL/data   filer1:/vol/HSQLdst/data  Snapvaulted    00:23:23   Idle

filer1*> snap list HSQLdst

the cloned qtree is created with the snapvaulted flag causing the lun within it to be R/O.

        /vol/HSQLdst_c/data/data.lun    4.0g (4301821440)    (r/o, online)

When using snapshot older than the base snapshot for the clone:

filer1*> vol clone create HSQLdst_c2 -b HSQLdst sv_hourly.0

filer1*> qtree status HSQLdst_c2

HSQLdst_c2 data                    ntfs   enabled  normal

filer1*> lun show /vol/HSQLdst_c2/data/data.lun

        /vol/HSQLdst_c2/data/data.lun    4.0g (4301821440)    (r/w, offline)

Cause

This is by design. The clone operation inherits the SnapVault/QSM base snapshot as busy, therefore,making the SnapVault property clone as RO for the specified qtrees.

Solution

To resolve this issue, use the older snapshot as the base snapshot for the clone. In this way the clone will not inherit the base snapshot for that relationship. Then the clone will be created as Read/Write (RW).

Enabling CIFS Auditing on NetApp

Connect NetApp by using SSH or Telnet as a root and execute the command below on each controller;


options cifs.audit.enable on

options cifs.audit.liveview.enable on 

 (When Live View is enabled, an Access Logging Facility (ALF) daemon runs once a minute, flushing audit events from memory to the internal log file
/etc/log/cifsaudit.alf on disk. The ALF daemon also attempts to save and convert
ALF records to EVT records that can be viewed by Event Viewer. It does so
either once every minute, or when the .alf file becomes 75 percent full)
