Moving other filesystem from root filesystem

Charles Egbon — Fri, 07 Jan 2005 07:53:16 GMT

Hi Friends,

Please, I have installed SuSE Linux 8.2 (i586) - Kernel 2.4.20-4GB (4). And configured it to my network. But on running the following command I discovered that: /usr, /home, /opt, /tmp, /var, and /proc filesystem are all in root (/) filesystem. How do I move/recreate these filesystem to different partition?

Thanks.

Charles.

First of all, you know you don't have to move those filesystems to different partitions. If you realy want to, you have to find out if there is free space on /dev/hda drive or if there are other free partitions or drives in the system. Please type "fdisk -l " to display your partition info and we will see what you got.

Hi,
1/You must ensure that have enough space for make new patition or add new disk to your system.
2/Backup directory which you want to recreate.
3/Create new partition and restore data to new partition.
4/Mount the new partition to directory which you want to recreate.
5/Edit file /etc/fstab , and add new line, i.e.
/dev/hda4 /yourdir reiserfs defaults 1 1
instead of hda4 and /yourdir for your adapt to real system.

Hi Chris,

Here is the requested info:
linux:~ # fdisk -l

Disk /dev/hda: 10.1 GB, 10110320640 bytes
255 heads, 63 sectors/track, 1229 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Hi Charles,

It looks there is only 1 disk (/dev/hda)with 2 partitions (hda1 and hda2) in the system. I saw no free space nor available partitions for you to move the filesystems to different partitions. You have to add disk(s) and replace the 10G disk with a bigger one to accomplish your goal, if you realy want to do so.

Hi Charles,

It seems haven't free space to recreate new partition. And I give you 2 suggestion.
1/ add new harddisk to recreate new partition and mount point , like my foregoing suggestion.
2/ backup useful and important data , and reinstall os , recreate appropriate size partition, then restore data

Hi Guys,

Thanks for all your suggestion, I think, I will just backup relevant files and reinstall the OS. Though, I have being trying to dodge from reinstallation and adding more hard drives.

Cheers.
