Pools lost but can be seen

TrueNAS General
1

Ok So I had a power outage, had to replace my modem/router.
I have a new IP not the default 10.0.0.50 truenas does. whatever.
I get in and all the pools/datasets are gone.
After a moment of panic I click create pool wizard and can see the storage drives/pools listed.

Anyone know how I can get those back into usable system pools/datasets without erasing them??? There is almost 6tb of data in there.

Why have you posted twice: here and Pool disappeared ?

If you want help to try to get your data back online then you need to stop griping and ask for help instead - and provide us with details of your hardware and pool configurations.

In the mean time here are some commands to run (and please paste the output from each into a separate </> box):

  • lsblk -bo NAME,LABEL,MAJ:MIN,TRAN,ROTA,ZONED,VENDOR,MODEL,SERIAL,PARTUUID,START,SIZE,PARTTYPENAME
  • sudo zpool status -v
  • sudo zpool import
  • lspci
  • sudo sas2flash -list
  • sudo sas3flash -list
  • sudo storcli show all

P.S. I have a feeling that what you are seeing is explained by the following:

  • Linux has one view of what ZFS pools are mounted
  • TrueNAS keeps its own UI record of what pools should be loaded

and what you are seeing is TrueNAS showing you what it thinks exists rather than what Linux has imported and mounted.

AFAIK, this is also how the Core UI also worked - so you could well have had exactly the same issues on Core.

That’s a different user though?

That was just the wrong link.
I think this is the one @Protopia was thinking of:

I’m sorry, 2 car accidents then just wanted to sit down run a backup and watch a movie.
Thank you for the help.

Do you see the missing pools on the dropdown when you go to Storage > Import Pool and if so are you able to import them?
