 Posted: Sat Nov 13, 2004 11:51 am Post subject: cfdisk knackered... |
 |
|
cfdisk is reproting the "ends beyond the final partial cylinder" error, and i think it's because my /dev/hda3 starts before /dev/hda2 (god only knows how), but I just thought I'd get some confirmation, If this is the case, what can I do to sort it out?
Here is the output of fdisk p:
| Code: |
Device Boot Start End Blocks Id System
/dev/hda1 * 1 4 32098+ 83 Linux
/dev/hda2 5100 12515 59565082+ 5 Extended
/dev/hda3 5 5099 40925587+ 83 Linux
/dev/hda5 5100 7124 16265781 83 Linux
/dev/hda6 7125 7762 5124703+ b W95 FAT32
/dev/hda7 7763 12226 35857048+ 83 Linux
/dev/hda8 12227 12364 1108453+ 82 Linux swap
/dev/hda9 12365 12515 1208938+ b W95 FAT32 |
Can i save my datain any way ( I am prepared to delete hda,2,5,6,7,8,9) hda1 is /boot and hda3 is /. |

suck_ma_penguin,
You have /dev/hda3 physically on the drive before /dev/hda2 but thats OK. If you look at the layout taking that into account, I dont see any partition overlaps.
The error message is really telling you that you you are attempting to access some disk blocks off the end of the drive.
What does have to say about the total number of blocks on the drive and how does that relate to the end of the drive as described by the partition table?

Here's the output of hdparm, but I don't really know what I'm looking for in all that...

Also, here is the output from parted (different to fdisk)

suck_ma_penguin,
Theres no overlaps there either and both the final partition and the extended partition go right up to the end of the drive.
Can you cut and paste the full text of the cfdisk error and the partition table as cfdisk sees it ?

Full cfdisk output is:
| Code: | FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder
Press any key to exit cfdisk |
I also get the following errors from gparted:
/dev/hda1 | Code: | This ext2 filesystem has a rather strange layout! Parted can't resize this (yet).
|
/dev/hda5 | Code: | This ext2 filesystem has a rather strange layout! Parted can't resize this (yet).

| After a bit more sniffing using parted, I think there are gaps between some of my partitions. Could this be confusing things? |

suck_ma_penguin,
Did you use cfdisk to format this drive?
I suspect that the problems are caused because the partitions do not start on cylinder boundaries.
The concept of cylinder boundaries is no longer relevant but it confuses some partitioing programs.
Does fdisk flag problems ?

The only thing fdisk says is that my cylinders aren't 1024 long or whatever, which I know doesn't matter. If not having used cfdisk is the reason, why is it confusing parted too?
Can I just delete /dev/hda2 with all the extended data and change my fstab to /dev/hda2 instead of /dev/hda3 and linux will still boot? |

suck_ma_penguin,
/dev/hda2 is your extended partition. It contains all the partitions from /dev/hda5 on. If you delete it you delete those partitions too.
You really don't want to do that.

Actually, that's exactly what I have been meaning to do for ages, this gave me a kick up the arse; it contained windows and an old linux install. Now I have:
| Code: |
cfdisk 2.12
Disk Drive: /dev/hda
Size: 102935347200 bytes, 102.9 GB
Heads: 255 Sectors per Track: 63 Cylinders: 12514
Name Flags Part Type FS Type [Label] Size (MB)
------------------------------------------------------------------------------
hda1 Boot Primary Linux ext3 32.91
hda3 Primary Linux ext3 41907.81
Pri/Log Free Space 59912.94
hda2 Primary Linux swap 1077.52
[Bootable] [ Delete ] [ Help ] [Maximize] [ Print ]
[ Quit ] [ Type ] [ Units ] [ Write ]
Toggle bootable flag of the current partition
|
I need a way of extending my main partition (some kind of rescue disk with parted?) and also, I need advice on a partitioning scheme:
I have tried separate /home and /mp3 (for my music), but I always run out of space! Any advice welcome.
Thanks a lot for all your help, even if I did just delete everything in the end! |

suck_ma_penguin,
Heres what I have by way of partitions | Code: | Filesystem Size Used Avail Use% Mounted on
/dev/hda5 7.6G 2.6G 4.7G 36% /
/dev/hda6 16G 11G 3.5G 76% /usr
/dev/hda7 1.9G 954M 879M 53% /usr/local
/dev/hda8 966M 251M 666M 28% /tmp
/dev/hda9 31G 7.9G 21G 28% /var
/dev/hda10 93G 53G 37G 60% /home
none 507M 0 507M 0% /dev/shm
eccles:/home 1.9G 1.3G 526M 72% /mnt/eccles
/dev/hda1 69M 11M 55M 17% /boot
|
<swap> is 2Gb
I don't know what to do about resizing, not having done it.
