Hi, i am running dietpi on RB3. There is an external HDD mounted and two USB device also mounted in a raid1 configuration. LSBLK gives me the list of the devices sda,sdb,sdc.
I would like to see the contents of each device separetly. How do i do it? Using ls -l for the mount point does not give me the information in which device files are located. SDB device mounted in /mnt/raid1 SDC device mounted /mnt/raid1/SMB. I guess it is not the wisest solution…
thanks

You need to mount the raid drive and not the individual raid members.
And why not mounting the separate individual disk to an own mount point?
Can you share following
```auto
lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid
```

You are mounting the external Transcend device to the very same location as your raid is mounted on. Still I would recommend to mount SBC to an own mount point.

Yes that is what i thought too. However i still would like to see what is on raid volume sdb1. It is 60GB the nextclud\_data occupies only 18GB according to du -sh. How can i monitor the sole content of that device md0?

I think you can do this with [mdadm](https://linux.die.net/man/8/mdadm)

you can’t mount individual raid member. It always needs to be the whole raid `md0`.
To check 20 biggest files on our raid, ensure to `umount` the flash drive first or mount it somewhere else. Once done, you can do following
```auto
du -a /mnt/raid1 | sort -n -r | head -n 20
```

So i have to unmount both flash drives first?

`umount` the Transcend device `sdc`
`sda` and `sdb` needs to be connected as they are member of raid group `md0`
