How should I navigate to my sdb drive?

Please find the details of my ubuntu directory,

NAME                           MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda                              8:0    0   300G  0 disk

sdb                              8:16   0   150G  0 disk
sr0                             11:0    1  1024M  0 rom

when I take remote /home through the WinSCP it seems I am able to have 76GB of memory. Although my sdb which is 150GB is empty. Can anyone help me how to access sdb via WinSCP?

TIA

4You need to mount it but it doesn't look like you have any partitions setup? – Seth – 2018-04-30T11:41:31.217

And the partitions would be like sdb1 or sdb2 in sdb just like sda1 , sda2 and sda5 in sda. You will be accessing sdb1 and like them. – C0deDaedalus – 2018-04-30T18:37:48.267

@C0deDaedalus , could you please explain a bit more as I am novice in ubuntu. – Aman Dalmia – 2018-05-02T12:40:14.230

Simply said To access any partition , you must have a mount point. In your case partition sda has mount points with labels as sad1, sda2 and sda5, but I don't see any of it for sdb. To make sure a partition has mount points run df -kh and look in the last column. – C0deDaedalus – 2018-05-02T14:47:31.453

@C0deDaedalus, i have done that, please see the result. Seems sdb doesn't mounted. Can you please tell me the process how to mount sdb to "/" such that I can get space when I am working through WinSCP. – Aman Dalmia – 2018-05-03T08:08:48.327

"how to mount sdb to /" – It looks like what is currently mounted under / is an LVM volume. Do you want to add /dev/sdb to it? Or move the OS entirely to /dev/sdb, so at the end the sole /dev/sdb (or better /dev/sdb1) would hold your /? Or mount /dev/sdb (sdb1) somewhere else separately? – Kamil Maciorowski – 2018-05-03T08:17:38.387

@KamilMaciorowski, Hi, actually the system is a VM and I am accessing the files via WinSCP. Due to the memory constarint of 75 GB, I asked for more space and they allocated me.

sda increased from 150 to 300 and sdb of 150GB got allocated. But still I am seeing the space for /dev/dm-0 remains 75GB.

My main agenda to increase the size of the /dev/dm-0 – Aman Dalmia – 2018-05-03T09:29:57.637

Please, instead of explaining in comment(s), [edit] the question and add all the relevant information there. Your question should be self-contained and you shouldn't expect users to read all the comments. // Probably the procedure will be: (1) create new partitions; (2) add them to LVM; (3) expand /dev/dm-0; (4) expand the filesystem within /dev/dm-0. // Please paste the output of fdisk -l /dev/sda, fdisk -l /dev/sdb, mount. This won't show us your LVM setup though. I'm not familiar with LVM, so I can't guide you in this aspect. – Kamil Maciorowski – 2018-05-03T13:36:20.117
