I/O size (minimum/optimal): 512 bytes / 512 bytes FDISK 2 :~# fdisk /dev/sdbĬhanges will remain in memory only, until you decide to write them.īe careful before using the write command.ĭevice does not contain a recognized partition table.Ĭreated a new DOS disklabel with disk identifier 0x90d7397a. Sector size (logical/physical): 512 bytes / 512 bytes Some irrelevant command outputs were removed: $ sudo -i

Here is an actual operation in progress, with the full output. Here is shortened way of explaining all the layers:Īdd hardware->sudo->fdisk->pvcreate->vgcreate->lvcreate->mfks->mkdir->mount->fstab – Then you update the operating system to tell it about the new drive. – Then you make a file system, taking a note of the UUID If you have a box, you add a new hard drive with a Philips screwdriver.First you create a hardware disk if you’re using virtualisation.What they never explain to you are all the layers. If you can follow the commands you can do a TL DR and get into the fast lane with adding new disks to Debian based distributions.Īn actual breakdown is roughly as follows. See here if you simply want to add a new EXT4 disk without LVM.īelow are the commands used to get the whole operation going. If you have vanilla EXT4 and you want to enlarge it, then you need to work out extents and at this point we feel it’s too complicated and technical. The reason why we love LVM is because when you need to increase the space it’s really easy.
