builders for centos8_regression don't have passwordless ssh configured

[xhernandez]

Many tests from centos8_regression job fail because the passwordless root ssh seems to be not properly configured in the builders.

From the logs of the jobs:

  16:33:48 ok   5 [     69/    294] <  34> 'gluster --mode=script --wignore volume create secondary replica 2 172.31.9.20:/d/backends/secondary1 172.31.9.20:/d/backends/secondary2 172.31.9.20:/d/backends/secondary3 172.31.9.20:/d/backends/secondary4'

It seems that the issue only happens on builder-c8-3

[mscherer]

yeah, builder-c8-3 was full, so it is possible it broke something, either during test, or for deployment. Does it still happen after we cleaned the builder ?

[mscherer]

Also, I see that:

# wc -l .ssh/authorized_keys 
313 .ssh/authorized_keys

That's maybe a cause of trouble, as I suspect ssh stop after a while. If the test do not clean after themself, that's a problem :/
