Locate second disk path from ssh and copy a folder to it

ASTRAPI · 06-09-2010, 06:25 AM

Hello

I own a web server (centos 64bit with cpanel on it) and my datacenter add me a second hard disk and i want first to locate from ssh where is it (the path) and then to copy my mysql folder /var/lib/mysql to the new disk and have it like this /new/mysql on the second disk...

Thank you

If the HDD is already mounted, use the "mount" command to see where it is mounted.
If not, guess that you should format it by yourself (by using fdisk/parted and mkfs.ext3), and afterwards mount it ("mount /dev/sdXY /where/to/mount", where X=HDD's letter (the first HDD is a, second is b and etc) and y=partition number, starting from 1).
Afterwards you can use the cp command to copy the mysql folder to the new HDD.

Thank you

a combination of df & sfdisk -l should give you the name and location of the new disk.
i suspect you will need to mount this disk to the directory of your choice too...
I will assume you know how to copy the /var/lib/mysql folder to the new location

Id try "df -h" or try to check "dmesg | grep hd" (or sda, hdb). Once you locate it do mount like Dracuss said.

The only think is how can i add a file system ext3 ?

mkfs.ext3

I need the exact command after partitioning please...

Thank you

Code:

mkfs.ext3 -b block-size /dev/hdb1

man mkfs.ext3

mkfs -t ext3 /dev/sdb1

That looks OK, but it has nothing to do with wanting only one partition...

First, you make the partition(s)---then create the filesystem(s)

I think your syntax is synonymous with:
mkfs.ext3 /dev/sdb1
