Don't try to create a logical partition with size 0

I'm not sure about growable partitions, are they allowed to have an minimum size of 0 ? If so, this patch needs some more work

Comment 3 Bishop Clark 2010-08-29 03:46:05 UTC
I ran into this error with a kickstart like:

logvol /home --fstype ext3 --name=home --vgname=vg01  [snip]
  --size 1 --grow --maxsize 5120

I suspect the 'size 1' is below the extent size (32 for me), and is thus rounded down (can we round it up?  two birds, one stone) and the resulting parameter passed into the lvcreate is 0.

In my case, after seeing this error, I bumped the size of the VMDK and restarted my kickstart.  Same issue with 30Gb free, so I'm sure it had enough space to allocate.  After adjusting my --size to 32 (mb) initially, the error went away.  If I have time later, I'll grovel the code to be sure -- this is just a guess, right now, based on the behaviour, but I'd bet a latte on it.

anaconda 15.25 exception report

Reproducible with anaconda 15.25. When user selects autopartitioning, anaconda creates swap with size 0 MB:

vg_rtt6     37440
 lv_root    36928      /      ext4
 lv_swap        0             swap
 lv_boot      500      /boot  ext4
 Free          12

There is a traceback when writing changes to disks.

Comment 5 Fedora End Of Life 2013-04-03 20:21:15 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Comment 6 Adam Williamson 2013-05-12 22:07:22 UTC
dcantrell marked this as POST on 2011-04-19. The patch was https://www.redhat.com/archives/anaconda-devel-list/2011-April/msg00230.html . So far as I can tell it was never reviewed and pushed. However, the relevant file - pyanaconda/iutil.py - is rather different now, and the 'minswap' stuff no longer exists in anaconda or blivet git that I can see. So I'm pretty sure this bug report is now irrelevant.

Karsten, Bishop - if you guys still find this use case relevant, please test it with F18 or an F19 build and file a new bug if it's broken in some other way, but this bug report is just obsolete now, the relevant code no longer exists.
