 Posted: Tue Jan 25, 2005 2:40 am Post subject: resize reiserfs problem |
 |
|
Well, I have searched the fourms and found many similar issue but can't seem to find a solution. I think this should be an easy one.
I am trying to resize my root partition which is reiserfs like this.
| Code: |
resize_reiserfs -s +7G /dev/hda4
returned message is:
/dev/hda4 only with reiserfs of 1271137 blocks size only with reiserfs of 1271137 blocks size on it. Your are trying to to expand reiserfs up to 284400 blocks size.
You probably forgot to expand your partition size.
|
Then I ran
| Code: |
reiserfsck --check
reiserfsck --fix-fixable
reiserfsck --rebuild-tree
|
All apread to run fine.
After more searching I attempted to resize the partition using cfdisk. Not quite sure how to do this but I chose "Maximize partition", I and then recieve this error.
| Code: |
cannot maximize this partition
|
I've done all of this while booting from the Gentoo live CD so none of my partitions were mounted.
Here is what my partition table looks like
| Code: |
cfdisk 2.12i
Disk Drive: /dev/hda
Size: 80026361856 bytes, 80.0 GB
Heads: 255 Sectors per Track: 63 Cylinders: 9729
Name Flags Part Type FS Type [Label] Size (MB)
------------------------------------------------------------------------------
hda1 Boot Primary NTFS 5765.93
hda2 Boot Primary Linux ext3 41.13
hda3 Primary Linux swap / Solaris 518.20
hda4 Primary Linux ReiserFS 5206.61
Unusable 68491.91
|
I assume I must increase the size of the hda4 partiton before using the resize_reiserfs command. But that apears to be where I am stuck.
I've also tried parted but it doesn't have reiserfs support. So I also attempted to emerge the need tools to do so but they are masked.
Thank you. |

Can you post the output of
I want to see the cylinder numbers because I am guessing that your empty space is not located next to hda4. This means hda4 cannot be made bigger without also moving another partition. |

I think if you run resize_reiserfs without specifying the size it will automatically expand it to fill the entire partition...
That is assuming you made the partition larger  |

I haven't made the partition larger, I guess that's my problem.
I'm just not quite sure how to make my partition larger? |

I think that you can use fdisk or parted to do so.... beware: it's dangerous.
Your problem with unusable space is determined by having 4 primary partitions, which is the maximum number of partitions that you can have. You should change the last primary partition to an extended disk, and them allocate logical disks on it.

I've tried parted, no reiserfs support.
I though the resize_reiserfs would be all I needed.
/dev/hda4 is the last partition on the drive so I would assume I can expand it? |

resize_reiserfs will resize the file system, not the partition. There's a big difference. That's why you need to use GNU/parted, which does support reiserfs partitions as long as it it built with libreiserfs and the partition's starting point is unchanged. Check out the table and read the notes that apply.
The version that comes on the Recovery Is Possible CD works great. I've used it a few times. To get Gentoo's build of parted to work with reiserfs, you need to 'emerge progsreiserfs' (not to be confused with reiserfsprogs) before parted.

OK, "progsreiserfs" is masked. Being a nOOb I figure it's best not to try to override it.
I will try the "Recovery Is Possible" route.
Thank you |

Using parted off the Recover Is Possible CD did the trick.
Thanx for all your help.
ps I attempted QParted off Knoppix... no luck. |

Hi ronmon, I read your post above.
I would like to use Qtparted to resize a Reiserfs partition to make it smaller. I realise I require libreiserfs which on Gentoo comes as part of progsreiserfs which is masked by ~x86.
My question is: if progsreiserfs is masked as unstable have you tried using it and is it worth risking using Qtparted with unstable progsreiserfs to resize my partition? I really don't want to screw up my hard drive! thanks |
