DAOS on CentOS 8

Farrell, Patrick Arthur
 

Good afternoon,

Has anyone been running DAOS on CentOS 8?  We tried this a while back, and had some significant issues related to 'python' referring to Python3 rather than Python2.  Before we try again, I was curious if anyone has been doing this & if there are any caveats or known problems.

Regards,

Hi Patrick,

 

I haven’t tried CentOS 8 but I’ve been using Fedora since version 27, now 32 and don’t recall issues encountered during the transition to python3 being the default.  Can you describe the issues you see ?

Jeff,

Currently, I'm finding many DAOS package dependencies are not in EPEL for CentOS 8.  Previously (last fall), I pushed through this - finding the dependencies from other, scattered sources, which obviously isn't ideal - and then I ran in to problems with the various Python packages which did not correctly handle the 'python' command being attached to python3.  Basically I ran in to a catch-22 where I couldn't get some packages to build if 'python' meant python3, and other issues with changing it back to python2.  It sounds like those are resolved if you're not having issues, so we can probably get CentOS 8 working if we push through the package issues.

Other than CentOS 7, does Intel have a preferred distribution to run on DAOS servers, or a list of those considered supported?

Hi Patrick,

 

Supported platforms are CentOS7, OpenSUSE 15.1, and Ubuntu 20.04

 

Most of the testing has been on CentOS7 so far though.

 

https://daos-stack.github.io/admin/installation/

 

I’d imagine CentOS8 is similar enough that it’s likely not a large porting effort.  We do have a ticket open to move to 8.

 

For my Fedora environment, I generally am first to find new compiler warnings and other such annoyances but I mostly work on VOS, the backend object storage for DAOS so don’t typically have the same requirements needed for a full stack.
