Truenas scale wont boot when I remove a drive (no pools involved)

[jamesarbrown]

It seems that when I installed there were two PCI drives, a plug in card with a SATA (where truenas was installed recognised as /dev/sdb) and the onboard host controller /dev/sda

When we drop out the onboard drive, truenas wont boot complaining at TrueNas Middleware, heap of errors and drops you to commandline.

It appears what Truenas needs to boot is not being done by UUID?

So i grabbed a fresh usb (not the RC2) I had, switched off the p420 HP Controller, fitted a Adaptec ASR in HBA with 8 disks.

Truenas was installed on the SATA under /dev/sdi and it booted ok.

Not sure which bit fixed this

Please note that the Adaptec ASR's have been problematic in the past. Also see

What's all the noise about HBAs, and why can't I use a RAID controller?

1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with, a server. RAID controllers typically aggregate several disks into a Virtual Disk abstraction of some sort...

Thankyou for support. The onboard was a HP P420 and I had read already it was both difficult to make it HBA and even then it was not a direct raw disk in JBOD

The adaptec is an ASR71605 which i bought knowing the adaptec in my desktop supported JBOD. In the BIOS menu though there was no JBOD mode and elected for HBA for now.. maybe I will get the Microsemi software up for this soon, but a quick check and I do believe I am getting the disk direct.

I suspect the introduction of the Adaptec (HBA Raw?) over the HP controller (in raid) was a primary solution. The DL385G8 just wouldnt play with other storage controllers and its fully off now.
