harddisk control (adding/changing)

[pbecks1963]

Hello,

I would like to see a tool with which i can manage my harddrives. By mistake i have a lvm group set up off 3 ide harddisk's. I would like to change all that (some day). But in the mean time i want to add a fourth ide harddisk. (not necceseraly to the lvm!)

?

[cpg]

is this guide on how to add drives to your amahi home server good for you?

[pbecks1963]

Hello cpg,

The script producess errors. I guess i'll have to start all over (re-installing amahi on the server) again to get things right.

No you don't need to reinstall.
You can extend your lvm with a 4th disk.

As posted in the installation section I'm going to experiment a little bit with it and post a tutorial...
If you can wait a couple of days I'll have the tut posted.

[pbecks1963]

Ok, great.. I'll wait

The script producess errors. I guess i'll have to start all over (re-installing amahi on the server) again to get things right.

well, that is a solution, however, if you could copy the errors, it would be helpful to understand why and perhaps fix them.

it would be useful to everyone.

it looks like you dont have fdisk installed, do

Code: Select all

su -c 'yum install fdisk'

[cpg]

i think fdisk is installed by default. in fact, it looks like it is in /sbin, per his listing above.

i think this may fix it:

Code: Select all

su -

the dash (-) is very important. without it, the user environment is what is being used. i.e. PATH does not include /sbin, which is where fdisk is located.

that or logging in as su directly.

after the su -, then run the Diskmounter.sh script.

[moredruid]

fdisk is installed by default on every linux distro.

Code: Select all

root@localhost #

I think running su - doesn't really help here if you're logged on as root, you'll just spawn another bash instance.
however, if you're elevating your rights from a normal user to root, you MUST run the command like this:

Code: Select all

su -

this will spawn a root bash (or whatever you have defined) shell, and include all the environment variables (like PATH, EXPORT etc.)
without the "-" it will just run a root bash with loading the .bashrc from root, which might produce the error.
