Re: [JLSE-Admins] sudoers (for Petrel AFM testing)

Okay. I misinterpreted our last emails regarding this. I was assuming no IB network connectivity for remote GPFS file system mounts, but there is literally no network connectivity. I had hoped to do NFS mounts over some management network just for testing. I'm not sure if there is a point to proceeding with this unless we are aloud to establish connectivity between the Petrel cluster and GSS. That was the whole point.

I think I went through the issues of this idea in an email back to you at some point, but Petrel and JLSE as a whole have to maintain isolation from production LCF. This is a key operating principal Bill and Mike have asked me to maintain since the inception of JLSE. This primarily means network isolation. As such, currently Petrel and GSS have no network connectivity outside of pubnet. I suggest we setup a new one-off testbed in the ISSF just for this use. This will have the added benefit of not disrupting Petrel. We will also need to have a discussion with Ed and Ryan about what networking should look like. As we're using them now, the ISSF file servers only have 1GbE uplinks, and are using Myrinet just for their own GPFS traffic. There really isn't any other options short of uplinking the Myrinet chassis itself with a 8x10GbE LAG, which we're really trying to avoid. If we really had to, we could setup the old tape movers as GPFS clients with 10GbE to Myrinet and 10GbE to the e600. We would be limited to 16 file servers (two S2A9900 couplets) in this configuration unless we forklift swapped ES5 for a core Myrinet chassis. In which case we would also loose Myrinet isolation between testbeds on the ES5 side of the room. Something Ed, Ryan, and I hoped to maintain. Let me know if you want to investigate these options further.

[JLSE-Admins] OS devel machine
by Kazutomo Yoshii 14 Aug '14

14 Aug '14

(Primarily to) Ben and Ken, # I'm on vacation tomorrow, I couldn't join the meeting. I'd like to bring an important topic. I have two Sandy Bridge machines at tinkerlab for the OS devel and apps co-design. I have full access, of course. These two have been helping lots of projects. But these day more people get interested in using these resources, even application folks. I'd like to have additional hackable resources. The BB clusters scheme works but I'm not sure I can do my work with the JLSE main resources. What I want to: - reboot with custom kernel. I can do this with PXE. - cycle power, console forward. change BIOS setting. IPMI is needed. CUI is preferred. - a dedicated disk partition is preferred (at least 10GB). - remote power cycle interface may be nice to have (in case IPMI failed) - I don't need to mount the home dirs during kernel work but some persistent disk partition would be nice. - regular users can also access the hackable machines when not in for the OS devel and app co-design. I think it is time share-able. NOTE: I can do IPMI and PXE configuration. I don't want to touch any system-wide resource such as NFS home dir, LDAP, etc. I don't want to maintain the image for regular users. I think this can not be fixed over night.maybe we can re-purpose BB cluster space for developer driven resources. Is this doable? - kaz

Do we have an interest in renewing the PGI 5-seat license? It expires in September, and since this is procurement's busy season we need to get the order in this week. Ben
