NFS allocation on NetApp with replication


Allocate 20G NFS storage to server1 with root, read-write access and set up replication for the newly created volume. If you want to learn about snapmirror click here

Step:1 Connect to the filer via ssh

ssh filer1

Step:2 Create thin Volume with name volA of 20g on aggr1

vol create volA -s none aggr1 20g



Step:3 Set volume Options

vol options volA snapshot_clone_dependency on
vol options volA try_first volume_grow
vol options volA create_ucode on

Step:4 Set snap options

snap reserve volA 0
snap autodelete volA on
snap autodelete volA commitment destroy
snap autodelete volA destroy_list vol_clone
snap autodelete volA trigger volume
snap autodelete volA target_free_space 5
snap autodelete volA delete_order oldest_first
snap autodelete volA defer_delete scheduled
snap sched volA 0 0 0@0

Step:5 Setup Single instance storage (deduplication)

sis on /vol/volA
sis config -s sun-sat@11 /vol/volA

Step:6 Edit exports file on the filer ---> Be very cautious

You can do this in different ways, I typically have a script that runs from my linux box to grab the exports file from filer /etc/exports to edit and send it back. If CIFS is enabled, you can edit it from your local note pad as well.

If you want to do it from filer, be extra cautious - if not you are FIRED!

wrfile /etc/exports

/vol/volA -sec=sys,rw=server1,root=server1,nosuid

Step:7 Refresh exports, validate

exportfs -a
rdfile /etc/exports

Step:8 Setup replication by logging into destination filer

ssh filer2

Step: 9 Create Replication Volume volA

vol create volA -s none aggr1 20g

Step: 10 Set volume Options
vol options volA snapshot_clone_dependency on
vol options volA try_first volume_grow
vol options volA create_ucode on

Step:11 Create Snapmirror relationship between source and target volume

snapmirror initialize -S filer1:volA filer2:volA

Step:12 Update Snapmirror config file to setup a job for updating the new volumes every 4 hours

wrfile /etc/snapmirror.conf

filer1:volA filer2:volA - 0 0-23/4 * *

Step:13 Validate

df -h volA
exportfs
snapmirror status
