I've used the referenced KB and I'm able to do whatever I want (i.e.: chroot all except certain users, chroot only certain users, use custom config, etc)

However, please note when using a custom config, the filename must match your full username that you use to login. In my case I logged in with a user 'YFISI\tohill'. So my custom config file is called 'YFISI\tohill' and NOT tohill.

In my setup below, only user 'YFISI\tohill' gets chroot and the chroot directory is /ifs/home/scratch as defined in its custom config file. All details below.

Content of my '/ifs/vsftpd/user_config' dir and the custom file for 'YFISI\tohill'

  yfvm-7111-2# pwd  
  /ifs/vsftpd/user_config  
  yfvm-7111-2# ls -l  
  total 26  
  -rw-r--r--    1 root  wheel  51 Oct 22 08:55 YFISI\tohill  
  yfvm-7111-2# cat YFISI\\tohill  
  local_root=/ifs/home/scratch  
  chroot_local_user=yes  

Permissions on the /ifs/home/scratch directory:

  yfvm-7111-2# pwd  
  /ifs/home  
  yfvm-7111-2# ls -led scratch  
  drwxrwxr-x +  2 root  YFISI\domain use  26 Oct 22 09:21 scratch  
   OWNER: user:root  
   GROUP: group:YFISI\domain users  
   0: user:root allow dir_gen_read,dir_gen_write,dir_gen_execute,std_write_dac,delete_child  
   1: group:YFISI\domain users allow dir_gen_read,dir_gen_write,dir_gen_execute,delete_child  
   2: everyone allow dir_gen_read,dir_gen_execute  

When I login with the 'YFISI\tohill' user, this is what I get:

  Name (192.168.32.222:xxxxx): YFISI\tohill  
  331 Please specify the password.

  -rw-------    1 ftp      ftp           373 Oct 22 13:21 test.txt

This is basically the content of the '/ifs/home/scratch' directory.

remove home directory

       rm -rf /ifs/data/sdi/

create subdirectory in new location if required

        mkdir /ifs/data/sony/sdi        

create symlink to new location

      ln -s /ifs/data/sony/sdi/ /ifs/data/sdi

re own folder

      chown -R sony:ftp_users /ifs/data/sony/

A few points to keep in minds:

- of course your jobs will be light-weighted and do no harm to the cluster…

- the crontab might get wiped when installing OneFS updates (even minor ones)

- you can't execute files from /ifs

1. - but you can execute scripts as /bin/bash /ifs/path/to/my/script

1. - if you put scripts or executables under a node's / or /var: these are small! and may get wiped, too.

- any node would do, but if it goes offline, there is no automated failover to another node (crontab is a basic UNIX thing)

Refer to this doc https://community.emc.com/docs/DOC-48465 for running CRON successfully on one node only

If email notifications are enabled, you can configure custom templates for email notifications.

If the default email notification templates do not meet your needs, you can configure your own custom email notification templates using a combination of text and SmartQuotas variables.

- Open a text editor and create a .txt file that includes any combination of text and OneFS email notification variables. -Save the template file as ASCII text or in ISO-8859-1 format. - Upload the file to an appropriate directory on the Isilon cluster. For example, /ifs/templates.

Example 1 Example of a custom quota email notification text file

The following example illustrates a custom email template to notify recipients about an exceeded quota.

The disk quota on directory <ISI_QUOTA_PATH> owned by <ISI_QUOTA_OWNER> was exceeded.
The <ISI_QUOTA_TYPE> quota limit is <ISI_QUOTA_THRESHOLD>, and SmartQuotas </Q>

Example 1 Example of a custom quota email notification text file (continued)

<ISI_QUOTA_USAGE> is in use. Please free some disk space by deleting unnecessary files.

The disk quota on directory /ifs/data/sales_tools/collateral owned by jsmith was exceeded.
The hard quota limit is 10 GB, and 11 GB is in use. Please free some disk space by deleting unnecessary files.

To use the custom template, click Cluster Managements > General Settings > Email Settings, and select the custom template in the Event Notification Settings area.
