Topic: Replacing the disk with a bigger one

[megl]

I have just cloned by SME-server disk (120 GB) onto a new disk (160 GB) using ddrescue because the old disk was 3 years old and I want to avoid HW failure.

I replaced the old disk with the clone.

The new disk works fine and boots correctly but it uses only the first 120 GB (of cause).

Because of lvm2 I can not use pmagic to expand the partition of the new disk to include the last 40 GB.

Can someone guide me to a description of how to utilize the last 40 GB of my new disk. Thank you.

Does this cover it

I cannot say if it works but this may help you

SME Server docs are quite good but there is a lot of reading etc involved look through the wiki before you proceed, some of the other guys here may be able give you better pointers

Thank you for the hints, but they do not cover my situation.

I have only one single disk in my machine and therfore running RAID 1.
I have cloned my single harddisk and now using the clone.

It it possible to create an extra partition in the free 40GB, and somhow including this space into my existing lvm2 partition?

Here's my fdisk -l output

Disk /dev/hdc: 160.0 GB, 160041885696 bytes

I hope you can help.

megl:

are you saying you have only 1 hd? well, in this case you are not safe at all, even if the hd is new (sometime this is worst)..

anyway, I suggest you to re-use the "old" (quoted as a 3 years old hd is not old.. I've 7 years old scsi disk running 24/24 without problems) in a raid1.

to do so:
- erase the mbr sector of your 120 GB hd
- add it via the manage console ("Manage disk redudancy")

in this way you'll get a 120 GB raid1 array.. you will not use al the space on the bigger one, but you will not suffer if one hd fails.

It should be possible, though tedious, for you to go back to the 120-gig drive, use one of the many contribs (DAR, Affa, BackupPC) to back up your server & data, then restore to a clean 7.4 installed on the 160-gig drive.
