I'm using a Maverick x64 LiveCD trying to change some partitions on a failed Clonezilla restore of a disk with Windows Vista on the primary partition and three partitions on an extended partition. Don't know if this is the same bug or not but when I try to delete the swap partition in the extended partition I get the following error (googled for MSDOS_MAGIC and found this bug). I was able to delete the ext4 partition sda7 just before it without a problem and the ntfs partition following it also (all three in the extended partition).
I need to get my system built back up soon and will likely start from scratch again with a Windows then Ubuntu install to get dual boot. And since I don't seem to be able to restore this configuration doubt that I will be able to help with a further repro. Error message from GUI after failed attempt to delete swap: Error erasing: helper exited with exit code 1: In part_del_partition: device_file=/dev/sda, offset=292844208128 Entering MS-DOS parser (offset=0, size=500107862016) MSDOS_MAGIC found looking at part 0 (offset 1048576, size 168036401152, type 0x07) new part entry looking at part 1 (offset 168038497280, size 332069340160, type 0x05) Entering MS-DOS extended parser (offset=168038497280, size=332069340160) readfrom = 168038497280 MSDOS_MAGIC found readfrom = 168042470400 MSDOS_MAGIC found Exiting MS-DOS extended parser looking at part 2 (offset 0, size 0, type 0x00) new part entry looking at part 3 (offset 0, size 0, type 0x00) new part entry Exiting MS-DOS parser MSDOS partition table detected got it got disk got partition - part->type=1 committed to disk Error doing BLKPG ioctl with BLKPG_DEL_PARTITION for partition 6 on /dev/sda: Device or resource busy -- palimpsest cannot delete partition/MSDOS_MAGIC found https://bugs.launchpad.net/bugs/518087 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
