Power9 distibution

[tommasoboccali]

Ciao, any chance to get Power8/9 distributions?

currently on a

[tboccali@login03 cvmfsexec]$ uname -a
Linux login03 4.14.0-115.14.1.el7a.ppc64le #1 SMP Thu Oct 3 05:32:24 EDT 2019 ppc64le ppc64le ppc64le GNU/Linux

cpu : POWER9, altivec supported

I get a

[tboccali@login03 cvmfsexec]$ ./makedist -s default
Making singcvmfs distribution for fedora7-ppc64le
No cvmfs package found from http://cvmrepo.web.cern.ch/cvmrepo/yum/cvmfs/EL/7/ppc64le

thanks!

Ciao, i made it working via some exchanges with @jblomer.

In practice, the distributions exist, but are in "non standard places"

with the git diff below, I got on Marconi 100

[tboccali@login02 cms.cern.ch]$ uname -a
Linux login02 4.14.0-115.14.1.el7a.ppc64le #1 SMP Thu Oct 3 05:32:24 EDT 2019 ppc64le ppc64le ppc64le GNU/Linux

[tboccali@login02 cvmfsexec]$ ./mountrepo cms.cern.ch
CernVM-FS: loading Fuse module... done
CernVM-FS: mounted cvmfs on /m100_work/INF20_test_1/cvmfsexec/dist/cvmfs/cms.cern.ch

The diffs are due to the facts that

• ppc64le cmvfs rpms are in http://cvmrepo.web.cern.ch/cvmrepo/yum/cvmfs-testing/EL/7/ppc64le (there is an added "-testing")
• centos ppc is an "alternate arch" and rpms are in a different directory tree

diffs:

Hi Tom,

I'm sorry I somehow missed the creation of this issue. I must have thought it was one of the cvmfs issues which I only glance at.

Could you please formulate this as a pull request? I don't have any Power8/9 systems to test it on so I'll rely on you to test it. Please also update the README.md where appropriate to refer to this support on CentOS 7 (& 8?).

Dave

i will have a look... the only problem is that i will need to modify makedist to use one URL _OR_ another .... clearly you will have a chance to see :) tom
