Comment 0 for bug 1784383

Currently the guided methods of the Ubuntu installer only address single disk setup. When a user have several disks on his machine he has to use the manual partitioning which is prone to failure for inexperienced user.

It would be useful to understand how many disks are installed on a system and their size.

This information is available from /sys/block/<device>/size . The information is in blocks. The block size is available from /sys/block/<device>/queue/{logical|physical}_block_size

For example on my system

$ cat /sys/block/sda/{size,queue/*_block_size}
125045424
512
512
