partitioner passes incorrect values to parted when using whole disk
Last modified: 2008-07-16 15:46:55 UTC
I get error -1007 when using whole disk on a 2.2G drive, sda3 could not be created.
Created attachment 49041 [details] bug115578.tar.bz2 hmm, scsi errors, will reboot and try again.
inst-sys:~ # fdisk -l Disk /dev/sda: 2164 MB, 2164083200 bytes 255 heads, 63 sectors/track, 263 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 3 24066 41 PPC PReP Boot /dev/sda2 4 188 1486012+ 82 Linux swap / Solaris There is a valid AIX label on this disk. Unfortunately Linux cannot handle these disks at the moment. Nevertheless some advice: 1. fdisk will destroy its contents on write. 2. Be sure that this disk is NOT a still vital part of a volume group. (Otherwise you may erase the other disks as well, if unmirrored.) 3. Before deleting this physical volume be sure to remove the disk logically from your AIX machine. (Otherwise you become an AIXpert). Disk /dev/sdb: 2164 MB, 2164083200 bytes 256 heads, 63 sectors/track, 262 cylinders Units = cylinders of 16128 * 512 = 8257536 bytes Device Boot Start End Blocks Id System inst-sys:~ # parted /dev/sda print Disk geometry for /dev/sda: 0kB - 2164MB Disk label type: msdos Number Start End Size Type File system Flags 1 32kB 25MB 25MB primary type=41, prep 2 25MB 1546MB 1522MB primary type=82 Information: Don't forget to update /etc/fstab, if necessary.
this is not only a PPC specific problem. I also had the same error while try to change/add/format partitions e.g. with FAT on usbsticks and exteral USB Harddisks.
Yeah, the current parted version is awfully buggy. It tells the disk having 1017 cylinders but refuses 1016 as last cylinder of a partition, strange. Could you get me access to the disk, so that I can try fixing parted.
the system is ananas.suse.de it worked ok in the second attempt, the logs are still on the machine.
I can reproduce it now. root@ananas , pwd foobar dd if=/dev/zero of=/dev/sd{a,b} bs=1024 count=1 install sles9 ga, leave partition proposal as is. install 10.0 rc1 and choose sda 'use whole disk' system is still in this state. /root/sda.bin has old partition map.
Now I see what causes this problem. Parted reports the disk geometry as 1017,67,62 as long as there are still partitions left from the SLES9 install. Accordingly YaST2 uses 1017 as the number of cylinders of the disk. Afterwards all partitions are removed from the disk. As soon as there are no partitions left on the disk. The disk geometry recognized by parted changes to 263,255,63. But YaST2 still uses the geometry from the initial disk scan according to the new geometry a partition number of 1016 is of course outside of the disk. Unfortunately there is no easy way out of this problem, since libstorage has so far no concept of a disk geometry changing between parted calls. - either we do not use "unit cyl" any more with parted but use one of the other units - or we add a command to parted that tells it which disk geometry to use Arvin, I am not in office tomorrow and we are approaching goldmaster pretty fast. So if you have any ideas that could help out of this dilemma feel free to implement them ;-)
something is really wrong with the msdos partition table concept. 2 identical disks, there was a sles9 whole disk install before. no way to repartition. inst-sys:~ # fdisk -l Disk /dev/sda: 36.4 GB, 36401479680 bytes 255 heads, 63 sectors/track, 4425 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 9 72261 41 PPC PReP Boot Disk /dev/sdb: 36.4 GB, 36401479680 bytes 128 heads, 32 sectors/track, 17357 cylinders Units = cylinders of 4096 * 512 = 2097152 bytes Disk /dev/sdb doesn't contain a valid partition table

it turns into this: inst-sys:~ # fdisk -l Disk /dev/sda: 36.4 GB, 36401479680 bytes 255 heads, 63 sectors/track, 4425 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 3 24066 41 PPC PReP Boot /dev/sda2 4 4425 35519715 fd Linux raid autodetect Disk /dev/sdb: 36.4 GB, 36401479680 bytes 255 heads, 63 sectors/track, 4425 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 3 24066 41 PPC PReP Boot /dev/sdb2 4 4425 35519715 fd Linux raid autodetect Disk /dev/md0: 72.7 GB, 72744173568 bytes 2 heads, 4 sectors/track, 17759808 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk /dev/md0 doesn't contain a valid partition table
Created attachment 49547 [details] bug115578-arvin.tar.bz2 Arvin provided an updated yast2-storage-lib, it doesnt fail with this new version.
Created attachment 49548 [details] bug115578-1G-swap.tar.bz2 a failure with Arvins changes, fresh disks, 70mb prep boot (was truncated to 8mb for some reasons) 1G swap, failed to create this swap.
Ok, this should finally be fixed in yast2-storage-2.12.29 in RC3
