Description Michael Cocke 2005-10-12 17:45:07 UTC 
In SuSE 10.0 boxed final, - in the expert partitioner, try to create a LVM
larger than 1.9 Tb - it doesn't - it wraps around to a negative number and
obviously doesn't create the partition.

Congratulations for the least meaningful bug subject of the year.
Comment 2 Thomas Fehr 2005-10-13 09:39:21 UTC 
Need y2log files from /var/log/YaST2/y2log
Comment 3 Arvin Schnell 2005-10-20 13:55:38 UTC 
The bindings from LibStorage to YCP cannot handle long long ints:
For values greater 0xffffffff the swig_sizeK_get of LvmVgInfo returns
nil and produces this error message in y2log:

[Y2Perl] YPerl.cc(fromPerlScalar):991 Expected integer, got float, SV
with TYPE: PVNV, FLAGS: TEMP NOK POK pIOK pNOK pPOK
[Y2Perl] YPerl.cc(callInner):336 ... when returning from LibStorage::LvmVgInfo::swig_sizeK_get

So not only LVM but all storage containers are affected -> critical for
SLES10.

Ugh. There's also some discussion in bug 75798.
Comment 5 Martin Vidner 2006-02-01 15:54:05 UTC 
Actually two bugs here:
- unsigned integers presented as signed
- not handling long longs.
Both fixed in yast2-perl-bindings-2.13.3.
