Adding drive to rockstor

[phillxnet (Philip Guyton)]

@petermc Hello again.

As soon as I connect it, it says it is part of my pool. That’s not right as I didn’t add it to my pool.

Thanks for the report: that’s quite a strange one.

@petermc

I have a couple of drives which start with this name,

ata-ST2000LM003_HN-M201RAD

I don’t think it’s related to the drive names as the kernel ensures that each drive has a unique name so we should be good there.

@petermc

I suspect it can’t distinguish the drives?

Yes, but we use device serial numbers to uniquely identify/track drives and their settings:

Device management in Rockstor

This is a wikified post documenting how Rockstor manages devices and is intended to serve as a live document on the same; user documentation is available at Disks. Please update this developer document when you make any changes to the disk management subsystem within Rockstor’s code. Also any suggestions on how this might be done better are very welcome; but please make sure that these suggestions are clearly indicated as such; this helps to maintain the relationship between this document and th…

@petermc

I used SSH to remove the partitions on the drive, but the same thing happens.

From this I’m assuming this is not a drive you have previously used with Rockstor or have installed Rockstor on. If it is then you may need to do a proper wipe, ie via ‘wipefs -a’ (very carefully), as just removing the partitions is not enough to remove any prior btrfs signatures.

@petermc

Is there anything I can do about this?

Hopefully yes. I can’t think currently how this could happen unless you are running a really really old version of Rockstor which from your previous posts is not likely (it was years ago now).

Could you first confirm your Rockstor version via a paste of the following command (run as root):

yum info rockstor

and to help diagnose what’s happening here it would help if you could post a screen grab of both your Disks and Pools page, with the problem drive attached, as well as the output of the following commands:

btrfs fi show

ls -la /dev/disk/by-id

and

lsblk -P -o NAME,MODEL,SERIAL,SIZE,TRAN,VENDOR,HCTL,TYPE,FSTYPE,LABEL,UUID

It would also be good if you could post any drive / pool related messages you find within your:

less /opt/rockstor/var/log/rockstor.log

which is also accessible via the Web-UI from System - Logs Manager (thanks to @Flyer).

I’m due to have another look at drive management in the near future so it would be good to understand what’s happened with your setup prior to that stint.

Thanks again for the report and lets hope we can get this one sorted as it’s quiet strange.
