OK, I have LDL disks working with the DIAG driver in parted now. The reason I was having trouble yesterday was that the LDL disk I was using for testing was formatted by a very old version of dasdfmt. Debian Squeeze currently uses version 1.6.2 of s390-tools. I upgraded to version 1.8.3 from Sid and reformatted the disk. This version uses the "version 2" format of an LDL disk label, which contains the number of formatted blocks in the label. Without this information in the label, which the old version of dasdfmt did not supply, parted relies on device geometry to calculate the size of the partition. And device geometry is all bogus when using the DIAG driver. Upgrading to a newer version of s390-tools and reformatting the disk solved the problem.
Now on to the final frontier: FBA DASD. -- .''`. Stephen Powell : :' : `. `'` `- -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
