SOLVED Help, My folder dissapeared! ZFS Rename of similarly named folder!

[Norlig]

Hi,

I have a folder I had a lot of data on, named for example "ThisFolder".
This was made in windows via the samba share, but I wanted to make it as a Dataset with proper permissions.

I made a Dataset called "ThisFolder0" and set my permissions to that Dataset, plan was to copy the files from "ThisFolder" to "ThisFolder0" then rename "ThisFolder0" to "ThisFolder"

But I did not get that far, as before I even copied any data and renamed the Dataset, I ran "zfs rename <pool>\ThisFolder0 <pool>\ThisFolder1"

Now "ThisFolder" is gone from my pool!
cant see it on the SMB share and cant see if it I open the TrueNas Shell and cd to the <pool>/ and type ls.

The Disk space is unchanged, so I am hoping the files are still there somewhere and can be recovered!

Please help :<

System details:
Version: TrueNAS-12.0-U6

And mount, please ...

Although if I just take a guess you could try zfs umount <MyName>-ZFS2-RAID-NAS/ThisFolder1 and check if your other folder reappears.
