Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

/tmp space requirement

We've run into stuff like this before. I think a lot of these requirements are from the purescale side, but they are being applied to all systems We address the /tmp space requirement a while back so that it is a warning now (although it still causes db2_deinstall to fail, DOH!)

We've been hitting two others with this upgrade.

/var - is required (by db2prereqcheck, which is run by db2iupgrade) to have 2Gb free. Db2 uses a little space in /var for the global registry but it is nowhere near 2 Gb. We had to write a custom script to add minimal space to /var just for this upgrade even though Db2 doesn't use it.

/usr – is required (by db2prereqcheck, which is run by db2iupgrade) to have 512Mb free to install Db2. DB2 upgrade does not use /usr at all. There are no instance or installation files in /usr

Since db2iupgrade runs db2prereqcheck and fails if any errors are hit, we can't upgrade a system without these unnecessary space requirements being met.

So I would like to see these turned into warnings like the /tmp message. And I'd like add that the same should go for db2_deinstall if those checks are included in that processing. I mean, we can rm –rf (and we do) but it seems like IBMs uninstall command should probably function.
