How to create volume in NetApp and how to NFS export

How to create volume in NetApp and how to NFS export

Introduction

NetApp Storage supports multiple protocols to access data like NFS, CIFS(SMB), FTP and WebDav etc. This article explains how to create NetApp Volume and export using NFS.

Step 1) Check Aggr Space and Ping Storage connectivity from server (where u will be mounting volume) –

# ping -c5 -M do -s 8972 192.168.0.10

netapp-filer1> df -hA
Aggregate                total       used      avail capacity
aggr2                     16TB       14TB     2320GB      86%
aggr3                     16TB       14TB     1681GB      90%
aggr0                   1490GB     1251GB      239GB      84%
aggr1                     16TB       15TB     1511GB      91%
aggr4                     12TB     5835GB     7044GB      45%
netapp-filer1>

Step 2) Create Volume –

netapp-filer1> vol create myvolume_bkup  -l en_US -s volume  aggr1 500g
Creation of volume ‘myvolume_bkup’ with size 1t on containing aggregate
‘aggr1’ has completed.

Step 3) Disable or Change snapshot and Reserve –

netapp-filer1> vol options myvolume_bkup
nosnap=off, nosnapdir=off, minra=off, no_atime_update=off, nvfail=off,
ignore_inconsistent=off, snapmirrored=off, create_ucode=off,
convert_ucode=off, maxdirsize=73400, schedsnapname=ordinal,
fs_size_fixed=off, compression=off, guarantee=volume, svo_enable=off,
svo_checksum=off, svo_allow_rman=off, svo_reject_errors=off,
no_i2p=off, fractional_reserve=100, extent=off, try_first=volume_grow,
read_realloc=off, snapshot_clone_dependency=off, nbu_archival_snap=off

netapp-filer1> vol options myvolume_bkup  nosnap on
netapp-filer1> snap reserve myvolume_bkup  0

netapp-filer1> df -h  myvolume_bkup
Filesystem               total       used      avail capacity  Mounted on
/vol/myvolume_bkup/      500GB      176KB      499GB       0%  /vol/myvolume_bkup/
/vol/myvolume_bkup/.snapshot        0TB        0TB        0TB     —%  /vol/myvolume_bkup/.snapshot

Step 4) Exports NFS –

netapp-filer1> exportfs -p sec=sys,rw=192.168.0.25,root=192.168.0.25,nosuid  /vol/myvolume_bkup

Step 4) /etc/fstab entry on Server –
192.168.0.10:/vol/myvolume_bkup     /backup nfs     defaults,hard,rw,rsize=65536,wsize=65536,proto=tcp 0 0
