lostdata on pool ZFS

[françois ROLAND]

I beleive i have made a big error :

I would like to upgrade my NAS4FREE from 9.2 to 9.3

to be sure, I removed 9.2 hard disk and use a new one to install 9.3

so, move to one, come back to other, I finsihed to loss my mind and was unable to see my ZFS pool

I tried to re creat pool ZFS (without format)

So, I get a pool empty (I don't find my data)

is Creat a pool ZFS erase all data ?

How Can I get back my data?

The usual procedure is:
-> Save your config
-> Install new Nas4free (embedded) on a empty USB stick
-> restore the config
-> synchronize the pool

If you create a new pool, you create a new pool and possibly overwrite the existing pool

How Can I get back my data?

From your backup?

OK

I said myself "I'm doing a stupid thing" when I click on RETURN key

Stupid guy I am

[crowi]

you can try from the commandline:

Code: Select all

zpool import

to list if any pools are there which can be imported
and

Code: Select all

zpool history

to see information about your pool(s)
