Description of problem: size of DVD1 is greater than 4GB on PPC, i386 and x86_64 Version-Release number of selected component (if applicable): RHEL6.0-20090911.7 Actual results: size of DVD1: PPC - 4572228 KB i386 - 4336162 KB x86_64 - 4309602 KB Expected results: size of all DVDs should be less then 4000MB Additional info:
(In reply to comment #0) > Expected results: > size of all DVDs should be less then 4000MB Why 4000MB? DVD size is 4.70 GB (4 700 000 000 B, 4.38 GiB). See http://en.wikipedia.org/wiki/DVD#DVD_capacity for details.
The standard that we use defines a DVD to be less than 4GB.
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion.
Without justification, an arbitrary 'standard' of 4GB is a ridiculous limitation. Dan is correct, a standard, singled sided DVD holds 4.7GB (4.38GiB). It is absurd to limit ourselves to less. If no one has a good reason besides "that's the limit in the test" I strongly suggest we change the test to be more in line with reality. I suspect someone wrote the 4GB limit into the test without actually knowing what the capacity of a DVD is.
Looking at: http://en.wikipedia.org/wiki/DVD#DVD_capacity I believe we are only planning to produce a single side/single layer DVD kit, so based on the DVD-5 (single side/single layer) entry: Type Sectors Bytes MB MiB GB GiB DVD−R SL 2,298,496 4,707,319,808 4,707.320 4,489.250 4.707 4.384 DVD+R SL 2,295,104 4,700,372,992 4,700.373 4,482.625 4.700 4.378 I believe it makes sense to change our testing parameter to 4.378 GiB ...

Can we close this?
iso size verification test already modified to reflect new DVD size. I think it's save to close this.
