Trying to recover deleted Volume

[ruic]

Hi!
I've tried everything that I saw in this forum already....
Someone here deleted a Volume on out local Freenas. Then he proceeded to create another volume with the same name! (don't know what he was thinking)...

This particular volume has no snapshots.... and no backup...
the "zpool import -D" comand returns nothing.

is there any hope?

Thank you!

There is no hope.

That is why root access must be tightly controlled.
You can absolutely destroy the system as root and the system will just do what it is told because you are root.

Yeah FreeNAS could benefit from user permissions. Ie user a can only create pools not delete them.
It's a big ask but it would be darn nice in larger environments where storage tasks may be delegated.

Uh, there ARE such things. See the manual pages. That said, ZFS may not have as much delegation as you desire. But more is being added all the time.

I vaguely saw a ZFS on Linux change for allowing more delegated permissions, like "destroy". Meaning a user may be able to then destroy his own snapshots, (of ZFS datasets HE/SHE owns and has delegated powers to do so).

These changes sometimes start on one of the 3 major OpenZFS platforms, Ilumos, FreeBSD or Linux. Whence it's working well, someone will create a pull request to get it on the others.

Allan Jude has a talk on YouTube showing among other things how to give zfs privileges to restricted users https://youtu.be/qXOZmDoy2Co around the 12 minute mark. The whole video is worth looking at though.

What you want is zfs allow https://www.freebsd.org/cgi/man.cgi?query=zfs

I know ZFS supports this but FreeNAS as a web managed storage server does not.

Ah, now I understand.

Yes, sometimes I wish some computer appliances supported limited function users. Root user would specify what each limited function user was able to do, like shutdown or reboot. Basically a list with check boxes.
