Hi,
i had to install Scale from scratch. I have 2 pools, one hdd for all my media data and one ssd for documents, fast transfers and also for my ix-applications. After the new installation the hdd pool is imported without problems, the ssd one can’t be imported. The server just restarts and the screen is not giving me any hints.
I could import the ssd pool on my manjaro distro on my computer without any problems… I could recover all data by just copy pasting it. Just the ix-applications folder is struggling a bit.
Heavyscript also did some backups, but the problem is can’t copy them over…
So how can i recover my ix-applications or at least the data?
And why can i import the pool on my laptop and truenas can’t import it?
connecting the ssd’s the same way i connected them to my computer (logilink sata reader) over usb
TrueNAS SCALE 24.04.2
Intel i7-7700K
Ram 64Gb dual channel
4 x 14TB hdd → Sata on mainboard
2 x 1tb ssd → Sata on HBA
GTX 1660TI
its not virtualized. Its on a seperate nvme ssd.
Why did you have to install TrueNAS Scale from scratch? Is this the first installation or were you trying to fix an issue with TrueNAS and reinstalled from scratch?
What kind of pool was the two SSDs? Striped, Mirrored?
What is the motherboard?
Have you tried checking the SATA cables and reseating them?
Are all the drives connected to onboard, SATA or is there a HBA involved?
Please give us the entire picture of what was happening and what is going on? Take us throught all the steps of the problem and what you attempted to do.
Reason to reinstall:
i had random restarts and the logs just gave me some random errors. The Truecharts community looked over it and told me, that there is something wrong with the kernal after some investigation. I should reinstall, test if everything is fine and then import the config. Thats what i did, just the import of the config failed.
Mail Pool is mirrored: so its 2 x 14tb and 2 x 14tb.
The ssd_pool (which i try to import) is also mirrored with 2 x 1tb.
MB: Asus Prime Z270-P
The mainboard has just 4 sata connections. Thats why i have a sata extender with 10 more sata connections. Its connected on the lowest PCIe connection. 3 of the hdds are connected to the mainboard, one of them is connected to my extender. Both SSD’s are also connected to the extender. The HBA i have is nothing special, a cheaper one. Trying to find out the name.
I am using Sata cables which are easier to bend like this one. I switched already between the cables and also i changed the connection to another sata extender. Everything is failing with a restart.
When i connect the SSD this message appears (but not always, trying out when exactly)
Can you look at your add on storage card and find a brand or other info? Since you mentioned cheap, I am thinking that is the problem. If you remove it maybe you can get make and model?
I wouldn’t mess with it any more and just get a detail hardware listing to post and compare against the guide.
SSD & hard drive make and models? We are looking for SMR issues, etc.
add on cards make and model, etc.
You can expand the DETAILS section of my signature to get an idea but my example is a bit shy on details and I only used it to get familiar with TrueNAS. I have multiple copies of the data elsewhere so I can lose the entire NAS while learning.
ok i understand. So i’ll change that for the future.
my first prio is now to get out the data of the ix-applications or the backup of heavyscript. Any ideas here?
As long as there are port multipliers involved in your system, Truenas and ZFS will not be happy and can cause your complete and unrecoverable loss of data.
So you saved your data, good.
Get yourself a 9300-8i, connect your drives.
With luck, if the pool is still ok, it will run.
Ok i will give that a try, but do you understand or can explain why it can’t read the pool, even if i use the same connections where the hdd is (directly on the mb)?
The last image there shows checksum errors. Those are typically hardware related and common causes are bad cables or bad connectors on the HBA/SATA-card, motherboard or the drive itself.
So i received my controller and flashed it to IT Mode (using this guide).
Unfortunately it’s still crashing. But this time it crashes directly without error codes…
I tend to use the command from the doc. But it says:
“Specify the txg to use for rollback. Implies -FX . For more details about pool recovery mode, see the -X option, above. WARNING: This option can be extremely hazardous to the health of your pool and should only be used as a last resort”
Blockquote
zpool import -F -nTX
but tbh i think that will also not work.
So i still don’t understand:
Why can my Laptop (Manjaro) read the pool but TrueNAS (creator of the pool) can’t?
