My Truensa is experiencing this issue after restarting. Is there anyone who can help solve it. Cannot lose data
Unfortunately I cannot translate the text on your screen captures so please write out exactly what is going on, how long it lasts, and affects the NAS. Be very descriptive, do not assume we know what you are talking about.
And Welcome to the forums!
Based on the symptoms described after the NAS reboot (failure to load hard drive data and information, inability to load datasets, SMB service failure, and inability to retrieve pool information via shell)
It’s been over 3 days now, and I didn’t dare to move because I was afraid of data loss
So anything happen before the system rebooted to this failed state?
Are you able to access the command shell? Any output for
zpool status
Do you have a back-up of your system configuration that you can import? With the very limited information here, I’d personally consider a clean install.
can you post a details on your system? Expand the ‘See My freeNAS system’ in Fleshmauler’s post by clicking on the little triangle. That is the kind of info we would be looking for.
How data pool disks are attached to your system. Do you have a HBA card connecting to the hard drives? What is your pool layout, Raid-Z1, Raid-Z2? What are the models of the hard drives. We are making sure they are CMR and not SMR for how they record data.
If you can’t access the GUI, do you have SSH access to the system or a monitor, keyboard and mouse attached to the TrueNAS machine? The console can be accessed those two ways if GUI is stuck.

zpool status Now it’s like this, I haven’t been able to return any results
not have HBA card
I have backup information from the last upgrade, can it be used
Yes - you have some options. First option; when you reboot, if you have keyboard & monitor connected to NAS (or if your motherboard has IPMI), you can choose which version to boot into. Try to see if the old version works.
Second option; reinstall TrueNAS. Afterwards, go to:
You can upload your backup from there.
Do you not know the root password? That will help with those sudo commands.
Also post the output of sudo zpool list to find out capacities. I am curious if you are too full.
The password you need need for sudo is the one used with admin, not root.
This password is the same password used to log in to the web GUI, so you clearly have this already.
If you were using su instead of sudo things would be different. But sudo is ideal for this, so use that.
I guess that explains it. I have my passwords the same. Doh!
GASP! Reusing passwords??!!111eleven
I would never do such a thing!
cough cough
In all seriousness, by adding a user to the sudoer group (or equivalent in TrueNAS) you have empowered that user with full priviledges, and you have effectively decided to trust them with their own password.
Then it is a good thing I am the only person to have access and use this system. It’s just a NAS for me, nothing more. I do have two user accounts that I use for SMB shares which have limited permissions.
I knew I would get some reaction for having root, admin, and truenas_admin all being the same password, easy passwords too. I normally only use root, anything else is too restrictive
