Root 6 at lxplus cern

ROOT
1

Dear Sir,

I was regularly using a specific root6 version (root6.06.08) and gcc (gcc4.9) for my analysis work at lxplus. I was sourcing them using

source /afs/cern.ch/sw/lcg/external/gcc/4.9/x86_64-slc6-gcc49-opt/setup.csh
source /afs/cern.ch/sw/lcg/app/releases/ROOT/6.06.08/x86_64-slc6-gcc49-opt/root/bin/thisroot.csh

This setup works fine for me up to 02.Feb.2019. Today while sourcing them I am getting the permission denied error.

I could see the /afs/cern.ch/sw/ directory, below is the output of

ls -l /afs/cern.ch/sw/

[kumarv@lxplus074 ~]$ ls -l /afs/cern.ch/sw/

total 30

the permissions for the lcg looks fine but

kumarv@lxplus074 ~]$ ls -l /afs/cern.ch/sw/lcg

ls: cannot open directory /afs/cern.ch/sw/lcg: Permission denied

I have checked with my colleague and he is also getting the same error. I
understand that this is not directly a root related problem but I was hoping people
may know the reason or may have feel similar problem at lxplus and can point me
to some solution.

with best regards,
Vineet Kumar

Hi Vineet,

my suggestion would be to move to lxplus7 (ssh lxplus7.cern.ch) and use the default ROOT, which is presently version 6.14/08, or, simply to source

/cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.16.00/x86_64-centos7-gcc48-opt/bin/thisroot.sh

which would setup the lastest root version: 6.16/00

Cheers,
D

I think that this is due to the discontinuation of AFS in general. Please use software from CVMFS and you will not have the same problem. As mentioned by Danilo, you can get almost any version of ROOT from /cvmfs/sft.cern.ch/lcg/app/releases/ROOT by sourcing the right file for your platform.

Dear All,

Thanks a lot for your reply. I will use the root versions
pointed out by you.

with best regards,
Vineet
