cannot open 'EllerData/Digital': operation not applicable to datasets of this type

Now I created a new ZFS volume and ran this last night

Code:

zfs send EllerData/Digital | zfs receive tank/dig

and this looks to of copied "something". Didn't have time this morning before work to check to see if what was copied is readable or not. I know the zfs send should be used for snapshots but how do you take a snapshot of a volume that is mounted read only ?

I will update once I get home and see if I can access the ISCSI lun

 

[Robert Trevellyan]

OK, no snapshots and no canmount property.

this looks to of copied "something"

That's encouraging.

zfs send should be used for snapshots

That's the normal use case, but I noticed recently that you can zfs send a filesystem, which is what you've attempted. I think you can only do this with a read-only pool, which is what you have. Fingers crossed.

 

[Slydogsz]

YES!!
Now recovering the data I didn't want to loose. Thank you all for the help,
I now have 8 3tb drives and after I get all my data backed up I am going to stick with a hardware raid 10 config and automate some backups to the cloud.

Thank you again.

So you are leaving FreeNAS? Or do you mean stripped mirrors?

Don't do this if you plan to continue using FreeNAS, or any ZFS-based solution.

I am re-evaluating FreeNas. I have a need to present storage to ESXi . ISCSI may not be the right choice for my lab and I may go with NFS instead. I am not sure at this point if I am going to use FreeNas as the head unit to present or go with Windows2012R2. There are a few folks here at work who are getting decent performance using Win2k12 to present NFS to ESXi .

I was dumb to mix my home stuff with my lab stuff and have corrected that. It wasn't critical stuff but the kids are happy to get their pictures back and are now storing them in the cloud (I hate that term).

Done with ZFS for personal use.
