UNIX for Beginners Q & A

Hi Experts,

I wanted to extend a veritas file system which is running on veritas cluster and mounted on node2 system.

#hastatus -sum

-- System State    Frozen
A node1  running 0
A node2 running 0
-- Group State
-- Group             System                    Probed                AutoDisabled              State
B    zone1            node1                          y                            N                                OFFLINE
B    zone1            node2                         y                            N                                 PARITIAL

-- Resources NOT PROBED
--GROUP                        TYPE                      Resource                        System

D Zone1                            NFS                       nfs                                   node1
D Zone1                            NFS                       nfs                                   node2
D Zone1                            Share                    ProdCI_share               node1
D Zone1                            Share                    ProdCI_share               node2
D Zone1                            Share                    Prodarchive_share     node1
D Zone1                              Share                    Prodarchive_share     node2

Node2:-

/dev/vx/dsk/zoneappdg/zoneappvol01 - /prod file system
Inside node2 there is zone1 running and using this /prod file system.

Node1:-

It doesn't mounted /prod file system.

Inside node1 there is zone1 is in configured state and /prod doesn't mounted

Now luns are added in servers and wanted to know if i grow and add disk in node2 will it expand?
Do i need to reboot the zone to get new values of /prod file system.
please someone suggest and give me the commands.

Here is some old 2011 reference material which may or may not be helpful.

YMMV

How to increase the size of vxdisk,volume, and filesystem following lun expansion.

Solution
First increase the size of the disk in vxvm:

# vxdisk -f -g <dg> resize <disk>

Example:

# vxdisk -f -g Cnv1 resize c13t1d0

Check to ensure size has increased by checking the 'dm' in vxprint output:

# vxprint -htg <dg>

Example:

# vxprint -htg Cnv1

Now check for amount of increase:

# vxassist -g <dg> maxsize

Example:

# vxassist -g Cnv1 maxsize

Increase the volume and filesystem size using output from previous command:

# /etc/vx/bin/vxresize -F vxfs -g <dg> <vol> +<size>

Example:

# /etc/vx/bin/vxresize -F vxfs -g Cnv1 vol30 +104857600

'

Verify with df command.

Hope this helps, but maybe not. It's a dated reference.

Cheers.
