Initial Request
----------------------------------------------------------------
Hi David,
Do you need on-going access to the real-time data, or just to a chunk of
sample data?
Because of SNAT's new security paradigm, the TCGP project has its own
dedicated UNIX group to enable a multi-developer environment. But I'm
not sure adding you to the group is the right way to add access. I'm
checking with SNAT to see if there is a more elegant solution. Another
easy thing would just be to copy some of the data over to somewhere
where you can access it.
The TCGP data are generally available on the public web site as well - I
can give you tips on where to find stuff.

Hi Jonathan -
Copying the data elsewhere should be fine for now,
though I do want to process a large volume of TC model output (global,
multiple storms over multiple years), the more the better ...
Let's come up with a storage space estimate and see if copying is
feasible.
thanks,
David

Copying this data seems like a bad idea.. it's 4+ TB !
Can it be made read-only for "world"? Then David can see it for
processing (I assume).

Hi Tor,
I just met with David. I didn't realize before he also needs the full
fields. Yes, we don't want to copy that.
I've opened up the portions of TCGP's ATCF repository space that he
needs:
(base) jvigh at eyewall:/d1/TCGP/data/data_realtime/ATCF$ ls -la
total 136
drwxrwsr--+ 21 jvigh tcgp 4096 Feb 25 18:47 ./
drwxrwsr--+ 12 jvigh tcgp 36864 Jan 5 08:59 ../
drwxrwsr--+ 2 jvigh tcgp 12288 Feb 25 18:47 adecks_open/
drwxrwsr--+ 2 jvigh tcgp 4096 Feb 24 00:49 bdecks_open/
drwxrwsr--+ 2 jvigh tcgp 4096 Feb 24 00:49 fdecks_open/
The gefs directory contains the GEFS fields (the 4 TB) that he needs,
but it's owned by Kerry's PhD student, Jonathan Lin (jzlin).
(base) jvigh at eyewall:/d1/TCGP/data/data_realtime$ ls -la
total 88
...
drwxrwsr--+ 21 jvigh tcgp 4096 Feb 25 18:47 ATCF/
drwxrws---+ 5 jzlin tcgp 4096 Jan 1 06:00 gefs/
...
I'm not able to open these up because I'm not the owner:
(base) jvigh at eyewall:/d1/TCGP/data/data_realtime$ chmod a+r gefs/
chmod: changing permissions of 'gefs/': Operation not permitted
Is this something a sysadmin needs to do? Or is there a way for me to
do
this?
Thanks,
Jonathan

Yeah, it's big enough to not want to do that..

Actually, the directories themselves need to have the eXecute bit set
too.
I'll show you an example below.

Here is a find(1) command that can do this all at once (run as root
since jzlin owns
some directories):
eyewall:/d1/TCGP# find ./data -xdev -type d -exec chmod o+rx \{\} \;
-type f -exec o+r \{\} \;
eyewall:/d1/TCGP#
The toplevel dir should be opened up as well so that David can descend
into the data subdir:
eyewall:/d1/TCGP# chmod o+rx .
eyewall:/d1/TCGP#
Please LMK if there are issues..
Thanks!

Hi Tor,
Thanks for the tips.
I've opened up the top-level directory, data, and data_realtime, but
it
won't let me modify any permissions for directories jzlin owns:
(base) jvigh at eyewall:/d1/TCGP/data/data_realtime$ chmod o+rx ./gefs/
chmod: changing permissions of './gefs/': Operation not permitted
(base) jvigh at eyewall:/d1/TCGP/data/data_realtime$ ls -la

I note that the directory already had o+rx permissions, but just for
kicks:
(base) jvigh at eyewall:/d1/TCGP/data/data_realtime$ chmod o-r gefs/
chmod: changing permissions of 'gefs/': Operation not permitted
So when I try running the find command on the ./gefs directory, I get
the following:
(base) jvigh at eyewall:/d1/TCGP/data/data_realtime$ find ./gefs -xdev
-type d -exec chmod o+rx \{\} \; -type f -exec o+r \{\} \;
chmod: changing permissions of './gefs': Operation not permitted
chmod: changing permissions of './gefs/2019': Operation not permitted
chmod: changing permissions of './gefs/2019/10': Operation not

chmod: changing permissions of './gefs/2019/10/29': Operation not

chmod: changing permissions of './gefs/2019/10/29/06z': Operation not

chmod: changing permissions of './gefs/2019/10/29/18z': Operation not

chmod: changing permissions of './gefs/2019/10/23': Operation not

chmod: changing permissions of './gefs/2019/10/23/06z': Operation not
permitted
chmod: changing permissions of './gefs/2019/10/23/18z': Operation not
permitted
It still can't change any permissions on the subdirectories, of which
there are many.
I'm not sure what to try next, apart from asking Jonathan Lin open up
the permissions on these.
It seems like there should be a way for me to manage this. If not,
could
this be a problem with the paradigm of using the shared group for
multi-development environments?

There is a bug in my find command. Here is the correct one:
eyewall:/d1/TCGP# find ./data -xdev -type d -exec chmod o+rx \{\} \; ,
-type f -exec chmod o+r \{\} \;
The second half of the find that changes FILES was not triggering.

Yeah.. my find was supposed to fix the perms for these files. :(
(so it is re-running now - and taking a lot longer as it is now
actually
touching each file)

You mean "multi-developER" environments? Yes. Advanced posix ACLs
can help
here but they are a PITA to manage.

I apologize for not being clear. It was not meant to work for you. I
was
just
wanting to let you know that the command was not syntactically
correct.
It seems that the users creating files in this directory hierarchy
should
simply
change their umask to 002 during the creation process. So that world-
read
gets enabled automatically. That would solve the problem in this
instance.
Thanks,

Hi Tor,
Thanks. I had wondered if you had already run it, based on something
you
said in your e-mail.
I'll ask Jonathan Lin to create the files with umask 002.
David - just wanted to check - are you able to access the files now?
Thanks,
