Troubleshooting

Resetting the admin password

If you forget the admin password you can reset it by logging into the system via the console or via SSH and then run these commands:

sudo -i
cd /opt/osnexus/quantastor/bin
service quantastor stop
./qs_service --reset-password=newpass
service quantastor start

In the above example the new password for the system is set to 'newpass' but you can change that to anything of your choice.

Storage pool creation fails at 16%

Many motherboards include onboard RAID support which in some cases can conflict with the software raid mechanism QuantaStor utilizes. There's an easy fix for this, simply remove the driver using these two commands after logging in via the console as 'qadmin':

sudo apt-get remove dmraid
sudo update-initramfs -u

Here are a couple of articles that go into the problem in more detail here and here.

The two commands noted above removes the dmraid driver that linux utilizes to communicates with the RAID chipset in your BIOS. Once removed the devices will no longer be locked down so the software RAID mechanism we utilize (mdadm) is then unable to use the disks.
