Extremadura2007MeetingMinutes

We had a little meeting about some FAI related stuff at the Extremadura work meeting in october 2007. Here are the minutes from this meeting:

Issues od setup harddisk(2)

There are currently problems to "preserve the right stuff" based on disk topologies. The problems relates to the inability of having the correct and same sorting of disks and device files for them. It is there in all newer kernels - which means since woody, probably. That means, it is no problem that is newly introduced by setup harddisk2. That doesn't mean, it should not be worked on, if possible, but it means setup harddisk is no regression regarding this if it cannot handle this correctly.

Possible things to do to solve it:

• set UUIDS at first install, and keep them somehow even through new installs, set disk configs to preserve by UUID
• Store serialnumbers of the disk in the disk config file, and preserve data based on this
• look into content of disks (e.g. .diskname) to preserve based on this (e.g. with the help of faimountdisk)

Apart from that, LVM with the new tool work fine - you can:

• keep some volumes by name
• Keep all volumes or none

Stockholm has some further requirements on setup harddisk:

• It should be possible to add physical volumes to existsing groups in lvm

Henning Sprang thinks, this is advanced, and more an update topic - "setup harddisk" is something else than "change logical volume config".

A proposal for next steps to do to work a structrued way to get setup harddisks well tested, with the goal of getting it into FAI soon (maybe as default disk config tool, or in parallel with the current one):

• create a list of goals of setup harddisk 2, and check if they are met
• create a list of existing serious bugs that prevent putting the tools into the next stable FAI version
• make a list of advanced wishlist things (like stockholm change stuff for lvm) - for the next version, on another wiki page
