Red Hat Bugzilla – Bug 61330
Bogus whining from anaconda about space
Last modified: 2007-04-18 12:40:59 EDT
Description of Problem: When eventually coerced to leave some space at the beginning of a disk for a boot block Disk Druid raises a stink claiming that a minimum 5 Megabytes of a free space is needed. This is totally bogus. The whole partition table sits on an initial disk sector, one more sector is left blank and a boot block, which is around 80k, starts on the next one. In other words around 100 KiB will leave some slack. In practical terms keeping the first cylinder free is more than ample. Depending on a disk geometry this likely will be between five to ten times more than a required space.
I know what you're saying just I can't guarentee this is going to be true for all disk controllers Phil =--=
Phil, disk controller has nothing to do with it. In a situation when half megabyte is a gross overestimate warnings about 5 Megabytes required are just counterproductive. One cylinder reserve is just a convenient way to partition things and as long as anaconda is unhappy with anything above, say, 250K just to leave a _very_ ample margin then I can only repeat that this is bogus and makes anaconda look clueless. So, do you know an example of a real disk controller and a disk with a cylinder below 100k? That would be pretty interesting with anything which realistically can be used. I am all ears...
At this stage of the game, with all the QA thats already been performed, I'm going skip on this one,.. think of it as space for future expansion. Phil =--=
