Installation errors for diracos

[andresailer]

I am seeing

bash /cvmfs/dirac.egi.eu/installSource/DIRACOS-Linux-x86_64.sh
/cvmfs/dirac.egi.eu/installSource/DIRACOS-Linux-x86_64.sh: /cvmfs/dirac.egi.eu/installSource/DIRACOS-Linux-x86_64.sh: cannot execute binary file

Because the file is all zeros?

hexdump /cvmfs/dirac.egi.eu/installSource/DIRACOS-Linux-x86_64.sh
0000000 0000 0000 0000 0000 0000 0000 0000 0000

1871cd10 0000 0000 0000 0000 0000               
1871cd19

But falling back to download and install

@atsareg can you check please?

The versioned installers are fine but the unversioned ones are all broken:

$ file /cvmfs/dirac.egi.eu/installSource/DIRACOS-Linux-*.sh /cvmfs/dirac.egi.eu/installSource/DIRACOS-2.42-*.sh

@atsareg We need a better way of responding to issues like this. It's unacceptable that CVMFS be in a broken state for this long.

you need to set a lower limit for the open file descriptor (max is 1024*1024). Full story : conda-forge/reproc-feedstock#10

you need to set a lower limit for the open file descriptor (max is 1024*1024). Full story : conda-forge/reproc-feedstock#10

How do I set the lower limit? This happens during the pilot installation phase at some CEs (e.g., RAL)?

You mean I have to reduce the max number of open file descriptors, right?
So just ulimit -n 30000 or something?

PS: Confirmed by @chaen via corridor discussion.

We have a fix (which I thought we were already using). I'll update DIRACOS2 shortly.
