Hi,
I’d be interested to hear if people have deployed or upgraded
CentOS/EL 7 on their clusters and what their experiences are? Also in
the more general sense, what kind of distro upgrade philosophy do you
follow? Are there a long-term roadmaps that you build internally, for
example?
Recently I’ve had some internal discussions about the prospect
schedule of upgrading our systems from CentOS 6.x to 7. I’m not
really keen on upgrading a major distro version unless there is a
_really_ compelling reason to do so, especially as we have driver
dependencies to Mellanox IB, Lustre, Tesla and Xeon Phi as well as a
lot of ISV codes. However, it would be nice to hear what the current
pain/benefit ratio of such an upgrade is.
One issue hindering me:
https://bugzilla.redhat.com/show_bug.cgi?id=1177032
kickstart install on machine with infiniband interfaces crashes
First, I admit to not understanding the problem in the bug report 100%.
Is it possible that you could pass a kernel argument to tell it not to
try to probe for IB interfaces, or something similar. I know this works
for video cards, etc., when they cause an install to hang.
