##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 (?).  Also,as an alternative specific snapshots can be created with specific names first and then create clone from that "named" snapshot:

    `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`
    

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`

5. User can now edit and modify 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"`
