##Setup for SSH Passwordless

On Filer:

1. Creates an access control role name vol_snapshot which only has access to the volume snapshot commands.

    `security login role create –role vol_snapshot –cmddirname “volume” –access all –query “”`

2. Create a user that has access only to the volume snapshot commands. 

    `security login create –username sadmin –application ssh –authmethod publickey –role vol_snapshot`
    

On Host:

3.  Generate an ssh key


    `ssh-keygen –t rsa`

 A public key file of form “id_rsa.pub” is placed in ~/.ssh directory. 

4. Cut and paste the public key generated in file and place as value on the filer.

    `cd .ssh`

    `cat id_rsa.pub`
    ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAsT18WDJho+recfdN77Qm7msj+LSgOZ7exSGMtM5N1//T5KJT1k4qXqY38j14Kn1pYAzeMaVGPd4uzC+q4wO8bKEZyoyfsLba4lzypNSf8sU4+MZ2xSiRd2KqRPb2up5Si64aJFnu+9Q98GhO2J5K/OzOQBoyCZW/ntZlZ0KNCz2o+L7osa2aEpgbupIz54qkO7Q2+es5RLg3FN+S6lmffq4whwu7WhVm6oAI6Rks7670ot1ydTOemdobICBtLXlJLwGicSaacWWh7C4v99GPDvx/r6atoY+BpEOQ7bM0s9eALcJ6njgGxpL71+iBBKb3beas5Za7ULgOJRxILjHJtQ== root@ibmx3755-svl03


5.  On Filer, Add the Key Information:

 `security login publickey create -username sadmin -index 2 -publickey "ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAsT18WDJho+recfdN77Qm7msj+LSgOZ7exSGMtM5N1//T5KJT1k4qXqY38j14Kn1pYAzeMaVGPd4uzC+q4wO8bKEZyoyfsLba4lzypNSf8sU4+MZ2xSiRd2KqRPb2up5Si64aJFnu+9Q98GhO2J5K/OzOQBoyCZW/ntZlZ0KNCz2o+L7osa2aEpgbupIz54qkO7Q2+es5RLg3FN+S6lmffq4whwu7WhVm6oAI6Rks7670ot1ydTOemdobICBtLXlJLwGicSaacWWh7C4v99GPDvx/r6atoY+BpEOQ7bM0s9eALcJ6njgGxpL71+iBBKb3beas5Za7ULgOJRxILjHJtQ== root@ibmx3755-svl03"`

##Create Base Template 

ASSUMPTIONS

* An aggregate, vserver and network interface has been created.

* The p4 server is running in order to do a p4 submit ** `p4d -p 172.31.10.101:1666 -r /mnt/p4db -J `pwd`/journal -q -L `pwd`/logs -v server=3 -v track=1 -d`

. 

1.  On filer, Create and mount volume on filer:
`vol create -volume ws_template -vserver perforce -aggregate p4 -size 30G -state online -type RW -policy default -unix-permissions ---rwxrwxrwx -junction-path /ws_template ` 
2. On host as root, Mount the volume using the network interface LIF:

    `mount –t nfs –o vers=3,local_lock=all,nocto  172.31.10.9:/ /mnt`
3. Extract the source in which template will be created. 

    cd /mnt/ws_template

    tar xvf /mnt/releases/linux-4.0.4.tar.xz

4. Define your p4 client  config:
    export P4PORT=172.31.10.101:1666
    export P4CLIENT=testaj
    p4 set
    p4 client

5. Add the source files to depots and submit
    find . –type f –print | p4 –x –add
    p4 submit

6. Build

    make

The above assume that the source files has not been checked in, however, if they are checked in then just do a "p4 sync", define "p4 client" and then make. 

##Create FlexClone Workspace For User

1. On Host as root, take snapshot and create FlexClone and then modify permissions and mount to correct junction path. NOTE: the ssh commands below can be combined to one line and the unix permissions do not need to be modified since those can be overridden at the host (?):

    `ssh sadmin@172.17.39.164 "vol clone create -vserver perforce -flexclone t1 -parent-volume ws_template -junction-active true"`

    `ssh sadmin@172.17.39.164 "vol modify -vserver perforce -volume t1 -unix-permissions ---rwxrwxrwx"
    ssh sadmin@172.17.39.164 "vol mount -vserver perforce -volume t1 -junction-path /ws1"`

    `ls /mnt/ws1`

    `cd /mnt/ws1`

    `chown -R tester:tester linux-4.0.4`
    
ANOTHER OPTION: One can also have the option to create a snapshot first of volume  and then create a FlexClone based on that snapshot.  

2. As user tester: 

    `cd /mnt/ws1`
 
3. Define your p4 client  config:

    `export P4PORT=172.31.10.101:1666`

    `export P4CLIENT=testeraj`
    
	`p4 set`

    `p4 client`

4. Run "p4 flush" to make workspace think it has the file content already.


    `p4 flush`

User can now edit workspace.

##Delete FlexClone Workspace

1. As user, delete client workspace

    `p4 client –d testeraj`

2. As root, delete flexclone volume workspace

     `ssh sadmin@172.17.39.164 " vol unmount -vserver perforce -volume t1"`

     `ssh sadmin@172.17.39.164 " vol offline -vserver perforce –volume t1"`

     `ssh sadmin@172.17.39.164 " vol delete -vserver perforce -volume t1"`
