How to add local ISO storage repo in Citrix XenServer

If you do not have a fileserver to host your ISO repository ,and you have a shared area on your XenServer that is formatted as EXT3 ,you can create a local ISO SR where you can place your ISO files.

Here, I have made a NFS share on the XenServer in order to move it to any file server later .

mkdir /templates
mkfs.ext3 /dev/sd(name of the device you will be used)

In my situation ,I have made an LVM from the local storage ,then format it ext3 as following :

lvdisplay

--- Logical volume ---
 LV Name /dev/VG_XenStorage-d9489c8d-de3a-67fa-df66-3246402ff671/VHD-491e4e3a-995b-4fbb-9846-3be3435ed13e
 VG Name VG_XenStorage-d9489c8d-de3a-67fa-df66-3246402ff671
 LV UUID leYnbC-Vsa5-ly1u-6lX0-EE08-WXi4-CpVdFn
 LV Write Access read/write
 LV Status available
 # open 1
 LV Size 30.07 GB
 Current LE 7697
 Segments 1
 Allocation inherit
 Read ahead sectors auto
 - currently set to 1024
 Block device 252:1

You may find that LV Status is unavailable ,so you have to run the following command ;

 vgchange -a y VG_XenStorage-d9489c8d-de3a-67fa-df66-3246402ff671

Then ,

mkfs.ext3 /dev/VG_XenStorage-d9489c8d-de3a-67fa-df66-3246402ff671/VHD-f7b358ff-2fdf-4a3e-8025-4737c6276d5c

mount /dev/VG_XenStorage-d9489c8d-de3a-67fa-df66-3246402ff671/VHD-f7b358ff-2fdf-4a3e-8025-4737c6276d5c /templates

Then, configure nfs share as following :

# vi /etc/exports
/templates 192.168.1.0/24(rw,async,no_root_squash)##write subnet you want

#exportfs -a

Note:You have to disable NFS4 as CitrixXen is working on NFS3 and edit portmap to listen to all IPs ;

#vi /etc/sysconfig/portmap
PMAP_ARGS=""

# vi /etc/sysconfig/nfs
 # Turn off v4 protocol support
 RPCNFSDARGS="-N 4"

/etc/init.d/nfs restart

[root@Raafat ~]# rpcinfo -p

 100005 2 tcp 741 mountd
 100005 3 udp 738 mountd
 100005 3 tcp 741 mountd

[root@Raafat ~]# showmount -e
Export list for Raafat:
/templates 192.168.1.0/24

It seems that everything is working with no problems ,now you can create ISO SR :

 xe sr-create name-label="Local ISO" type=iso device-config:location=192.168.1.10:/templates/  content-type=iso

Note:192.168.1.10 is the XenServer IP where we have created NFS share on.
