I have Ubuntu Server 14.04.3. I connected a storage unit (IBM Storwize v3700). I cannot getting it to be mounted to the server. I followed the following steps.
- install multipath
sudo multipath -ll
36005076300808b9e4800000000000003 dm-2 IBM ,2145
size=500G features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='round-robin 0' prio=50 status=active |- 1:0:0:0 sdb 8:16 active ready running
-+- policy='round-robin 0' prio=10 status=enabled
`- 1:0:1:0 sdc 8:32 active ready running
- create a partition table on /dev/sdb
sudo parted /dev/sdb mklabel gpt
format a partition
sudo parted /dev/sdb mkpart primary ext4 1G 500Gmount it on the folder /storwize I created
sudo mount /dev/sdb1 /storwize
This is where I have the error
mount: /dev/sdb1 already mounted or /storwize busy
I might be mistaken on what to mount, considering that fdisk -l gives me for my storage /dev/sdb, /dev/sdc (no partition table), and /dev/mapper/36005076300808b9e4800000000000003 (no partition table) (all with the size of my storage).
Here is the full output of
sudo fdisk -l
