Help! TrueNAS Scale recognize all driver of the pool, but dont auto import pool and cant manually import also

[phamthinh1368]

Hi all,
My Truenas system has 5 disks connected by Sata ports and 5 disks connected by PCIE-NVME-Sata adapter boards (JMB585), setup as RAIDz2. Its run for 2 months but when I replace CMOS battery, I got some issues here.

First of all, the system cant load TrueNAS while I still plugged 5 disks to adapter boards (dont show command line screen after POST screen for 10 minutes). BIOS still show 11 disks in my system (10 for pool, 1 for TrueNAS).

Second, when I move 3 disks to external USB-Sata adapters (2 disks leave outside because I dont have enough adapter), TrueNAS can load correctly but I meet the second issue here. I installed 2x8GiB RAM, BIOS recognize all of it but just 2.4GiB were recognized by Truenas. It make the copy speed is so low, just around 2-5MB/s (typically 100-120MB/s).

Finally, my TrueNAS system shown me 8 disks, but as 8 unassigned disks. TrueNAS know that all of my disk belong to my old NAS pool but dont auto import pool for me although RAIDz2 can work with 2 offline disks.

And when I import pool by manually, there is no pool there to import because dont have any pool option on it.

Can anyone help me to solve this problem? Or just help me copying data to another disks.

Thank you.

First off, loss of CMOS likely screwed up 2 things;

• Boot disk / boot order
• Amount of memory allocated to built in graphics

You don't list your hardware specifications, so it is a guess about the last one.

Go into the BIOS, correct the issues, and save.


Next, from the command line, run this command and paste the output in CODE tags here;
zpool import


Please list your entire hardware configuration. Including how each disk is wired, the make & model of each disk.


You have to be careful about "adding" disks of an existing pool. Under the wrong circumstances you can destroy your pool. When dealing with this type of problem, slow and steady are far more preferred.

Hi all,

Tks for all of your attention. After whole day research and debug, below is the whole story.

My system fail to connect to update server after each time electricity loss, so I assume that CMOS battery is drain out. After replacing CMOS battery, my BIOS reset to factory condition, leading to BIOS rolling back to v01.19 from v01.55.

This make whole system cant run as normal: cant detect all RAM, cant boot if PCIE-NVME-Sata adater being used...

Ive updated BIOS version and now its OK.

Again, tks all of you for reading my post.
