Upgraded from 13.0-U.2 to 13.0-U6.1 - Pool Offline

Not much joy, I don't think.
I will try to respond in order:

Code:

bear% zfs list -t filesystem -r -o name,mountpoint boot-pool/.system

Code:

bear% sudo zpool import
   pool: BigPool
     id: 12719548412266318029
  state: ONLINE
status: One or more devices were being resilvered.
 action: The pool can be imported using its name or numeric identifier.
 config:


        BigPool                                         ONLINE
          raidz1-0                                      ONLINE

            gptid/e4ac0488-4cb0-11ed-a5e8-bc5ff4664310  ONLINE

Code:

bear% zpool import -N BigPool
cannot import 'BigPool': no such pool available
bear% sudo zpool import -N BigPool
cannot import 'BigPool': insufficient replicas
        Destroy and re-create the pool from
        a backup source.

Code:

bear% zpool status -v BigPool
cannot open 'BigPool': no such pool
bear% sudo zpool status -v BigPool
cannot open 'BigPool': no such pool

Code:

bear% zfs list -t filesystem -r BigPool
cannot open 'BigPool': dataset does not exist
bear% sudo zfs list -t filesystem -r BigPool
cannot open 'BigPool': dataset does not exist

There being no "backup source" that I know of, my world may now be a few TB smaller than it was.
Right?

Thanks,
Dave

cannot import 'BigPool': insufficient replicas

Are all the member disks available?

Code:

glabel status

 

[wittend]

I'm not sure what this means:

Code:

bear% glabel status

All disks/partitions required for the pool's sole RAIDZ1 vdev are detected by the system.

Not sure why you're getting hit with "insufficient replicas".

What was the leadup to this? Apparently, the last status message in regards to BigPool was that it was in the middle of a resilver process. (But why? Was a disk failing? Did you configure a hot spare, per chance?)

 

[wittend]

No hot spare.

I wanted to see the exact model number of the drives to check the price and consider adding more. I wanted (perhaps) to create a new pool or something because I always get errors when working with git clone folders or anything with symbolic links.

I bumped one of the data cables and evidently corrupted one of the drives. I tried to understand how to repair things but only got more confused. Perhaps I interrupted the resilvering process. I did not understand what that was, and did not know that it was already going on. I waslooking for something like 'rebuild mirrors' or 'rebuild RAID'.

Unless you can backtrack and memorize what you did, it sounds like you inadvertently destroyed your pool, and hence your data.

Even if you can remember everything, it doesn't mean you can undo the damage; especially when dealing with entire drives and the resilver process of a pool.

You might try to see if you can import the pool in a degraded state:

Code:

zpool import -fFnN BigPool

 

[wittend]

I'm not sure if that did anything. As a regular user it returns 'no such pool'. As su, it returns nothing.

Code:

bear% zpool import -fFnN BigPool
cannot import 'BigPool': no such pool available
bear% sudo zpool import -fFnN BigPool
Password:
bear% bear% zpool import -fFnN BigPool
cannot import 'BigPool': no such pool available
bear% sudo zpool import -fFnN BigPool
Password:
bear%

 

[winnielinnie]

Can you try without the "-n" flag?

Code:

zpool import -fFN BigPool

 

[wittend]

When I run that with sudu via SSH terminal, I get:

Code:

bear% sudo zpool import -fFN BigPool
Password:
cannot import 'BigPool': no such pool or dataset
        Destroy and re-create the pool from
        a backup source.

When I run the same command from an attached console (kbd+ monitor), I get a raft of stuff that changes with repeated invocations. None of it looks promising, but it talks about different volumes each time.

I'm expecting a 10 port PCIe -> SATA controller later today. That should help cleanup the rat's nest of wires. I'm gong to keep watching this thing until that arrives.

Assuming that the clouds don't miraculously part by then, I will take this apart and start clean.

I must thank everyone who has made suggestions.
At least I can walk away from this car wreck with a lot of new information and maybe even a little more knowledge concerning how this works and what tools exist to manage it.
As always, that is the second best possible outcome.

Thanks,

Dave

Really make sure to read the following resource before using that.
