[gpfsug-discuss] Ubuntu 24.04

[Jonathan Buzzard]

Any indication when it might be supported?

The reason I ask is that we have an issue with Microsoft DFS shares. 
Basically the University provides shared space which under the hood is a 
Hitachi VSP. We have code that lets the user mount this shared space to 
move data on/off the HPC system. The issue is two levels of DFS 
redirects(*) which works fine in RHEL7, but is broken in RHEL8, RHEL9, 
Ubuntu 20.04LTS and 22.04LTS.

However today I took a punt and tried with a Ubuntu 24.04 LTS install 
and woohoo it works. So somewhere between 3.10 and 4.18 it was broken 
and not fixed till somewhere between 5.15 and 6.8.

Obviously I only have a couple weeks left on RHEL7 but was going to flip 
the server we put in place to support this to CentOS 7 ELS from TuxCare 
while looking for a solution. So having now identified Ubuntu 24.04 as a 
potential solution I just need GPFS support. I presume that 24.04 will 
be supported in due course but just trying to gauge roughly how long, a 
month, six months etc. to make plans.

* You mount the shared space which is a DFS share on a Windows 2019 
server. You see a list of faculties. You change directory into the 
faculty and historically these where a share for each faculty on the 
VSP. However some faculties now store more data than can be accommodated 
on a single share from the VSP, so now when you change directory into 
the faculty the list of departments is another set of DFS redirects and 
trying to change into these does not work.
