Re: NFS hanging

2015-11-03 Thread Nix, Robert P. 
In /etc/auto.master, we have:

/shares/nfs /etc/auto.shares.nfs-browse
/home/auto  /etc/auto.home


And in /etc/auto.shares.nfs, we have:

unixarch-squash_root,nodev,intr
rchunixvf01.mayo.edu:/vol/rchunixvf01_vol001_m/unixutils/linux-x86_64-redha
t-6
unixnoarch  -squash_root,nodev,intr
rchunixvf01.mayo.edu:/vol/rchunixvf01_vol001_m/unixutils/noarch
tivoli  -ro,soft,intr
syspzl01.mayo.edu:/appdata/tivoli


(Sorry in advance for the wrapped lines)

After the system is up, users can reference /shares/nfs/unixarch and
/shares/nfs/unixnoarch and will see the files that are on the various
netapp servers.

If the user absolutely positively has to have the disk at some other
location, we create a symbolic line where they want it, pointing into one
of the /shares/nfs paths.

You can choose your own base path; ours is just historical here. After
changing the files, be sure to run “service autofs restart” to pick up the
changes.

RHEL Linux training

2015-11-03 Thread Martin, Terry Contractor 
Hi

I want to suggest some Linux training (z/Linux) for Administrators that are 
currently mostly UNIX ADMINs. This customer is migrating from Solaris UNIX to 
either x86 Linux or z/Linux. Does anyone have any recommendations for specific 
training for experience UNIX or not so experience UNIX ADMINS that would be 
helpful. If there are any specific training courses that you know about that 
would touch on both x86 Linux and z/Linux that would be great!

Thanks for the help!!

Re: RHEL Linux training

Linux is Linux... and the jump from UNIX to Linux is pretty easy (even I 
was able to make the change back in `99).
- Might be good to just start with some basic Linux classes as that 
knowledge is easily transferable. 

Over really recommending one over the other I figured it might also be 
helpful to just list some options, noting that I am sure a custom session 
could be created if desire with financing really exist. 

All that said, Redhat does offer courses:
https://www.redhat.com/en/services/training 

The VM web site list eduction offers:
http://www.vm.ibm.com/education/ 

Marist with the IDCP has official course offering listed here, with one 
geared towards z/VM with Linux:
http://idcp.marist.edu/enterprisesystemseducation/enterprisesystemscoursecalendar.html
 


The VMworkshop in June is still rated as the best bang for the buck.  I 
just attended my first one this year and was very impressed.  Worth noting 
is that 2016 is slated to occur at Ruters Univerity in NJ:
http://www.vmworkshop.org/ 

And then there are of course labs at events like SHARE or InterConnect:
http://www.share.org/ 
http://www.ibm.com/cloud-computing/us/en/interconnect/ 

Hopefully all this info is helpful,

Re: NFS hanging

2015-11-03 Thread Nix, Robert P. 
You¹re attempting to mount an NFS or CIFS share before your network is up.

I¹d suggest making any NFS or CIFS disks auto mounted on first use, via
autofs. That way, they don¹t get mounted until after the system is up and
someone requests access to them. We do this with both NFS and CIFS shares,
and have no problems with them.

Robert,

Thank you. Do you mind giving me an example on how to do this?

I appreciate it.
