Hi, I have a problem with my partition table, which makes the system unbootable. Parted sees my partitions, but the kernel does not. If this not the right list to post my problem, please tell me where I could find help.
I have a Powerbook G4 dualboot with OSX and Ubuntu. OSX starts fine but if I select Ubuntu, yaboot starts it, but then it hangs at the Ubuntu splash screen (probably because the root partition is not found). I have done the following tests by booting from the ppcrcd live cd. During boot, no partitions are recognised # dmesg | grep hda [ 92.238964] hda: ST9100823A, ATA DISK drive [ 92.910783] hda: Enabling Ultra DMA 5 [ 94.667101] hda: max request size: 1024KiB [ 94.923239] hda: 195371568 sectors (100030 MB) w/8192KiB Cache, CHS=16383/255/63, UDMA(100) [ 94.923761] hda: cache flushes supported [ 94.932608] hda: # ls /dev/hda* /dev/hda fdisk sees nothing, sfdisk sees (4 times?) nothing, but parted sees the partitions # fdisk -l /dev/hda Disk /dev/hda: 100.0 GB, 100030242816 bytes 255 heads, 63 sectors/track, 12161 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System # sfdisk -l /dev/hda Disk /dev/hda: 12161 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/hda1 0 - 0 0 0 Empty /dev/hda2 0 - 0 0 0 Empty /dev/hda3 0 - 0 0 0 Empty /dev/hda4 0 - 0 0 0 Empty # parted /dev/hda print Disk /dev/hda: 100GB Sector size (logical/physical): 512B/512B Partition Table: mac Number Start End Size File system Name Flags 1 0.51kB 32.8kB 32.3kB primary 6 32.8kB 2033kB 2000kB hfs primary boot 3 134MB 15.0GB 14.9GB hfs+ primary 5 27.1GB 32.4GB 5243MB ext3 primary 2 32.4GB 42.9GB 10.5GB ext3 primary 7 42.9GB 98.0GB 55.2GB fat32 primary 4 98.0GB 100GB 2000MB linux-swap primary swap Now I let partprobe reread the partition table Note that I have not done changed anything on the partition table since booting # partprobe /dev/hda Now the partitions show up. They can be mounted and there seems to be nothing wrong with them. fdisk and sfdisk however still don't see the partitions # ls /dev/hda* /dev/hda /dev/hda1 /dev/hda2 /dev/hda3 /dev/hda4 /dev/hda5 /dev/hda6 /dev/hda7 If I reread the kernel partition table with sfdisk # sfdisk -R /dev/hda All the partitions are gone again # ls /dev/hda* /dev/hda What is going on, what is the difference between "partprobe" and "sfdisk -R". And how can I make my Ubuntu bootable again? The problems started after I resized a partition with parted.
