Preclear script can't find unassigned disk

[CaptainTivo]

I recently replaced an HGST 4 TB parity disk with an HGST 8 TB.  I precleared the 8TB drive, installed and parity-synced.  I then re-installed the 4 TB disk to a different port.  I went to run the preclear script on the  4TB and it could not see it!  preclear -l reports "No un-assigned disk detected".  I stopped the array and clicked on the dropdown assignment menu and the 4 TB show up there (see screencap).  Anybody know what's wrong?

Try after rebooting

No dice.  This odd, from what I can tell pre_clear.sh gets it's info from /boot/config/disk.cfg and so does the gui so they should see the same thing, right?  Attached is my disk.cfg file.

disk.cfg

The GUI uses disks.ini for devices in the array, and devs.ini for unassigned devices. These files are in the folder /var/local/emhttp.

I don't know if the preclear script reads these files though.

 

Have you considered to upgrade to V6?

[CaptainTivo]

Yes, I plan to upgrade but not before I have step-by-step list to move to mysql docker for my Kodi install.  I just thought I would pre-clear this disk first.  This has always worked for me before and I would like to understand why it is failing now.  Should I use the "new Config" util in UnRaid 5.0.5 to reset the configuration?

 

Just checked devs.ini and it has:

[device0]
id="HGST_HDN724040ALE640_PK1334PCJZXT9S"
device="sdj"
size="3907018584"

This is the old 4 TB parity disk that I want to preclear.  It just looks like the preclear script is not reading this correctly for some reason.  ????

Bump.  Still can't find a solution to this.

One source of array information is extracted from the /boot/config/super.dat file. Sometimes serial number of old disks remain there and that will keep your disk from being recognized.

 

You will have to edit the script to bypass that limitation.
