Hi everyone,
I’m running into an issue with my TrueNAS setup. When I try to open a dataset from the CLI, I get the following error:
cannot open 'BigTank': dataset does not exist
I’ve double-checked the dataset name, and everything seems correct. I’ve also included some screenshots to provide more context.
Has anyone encountered this issue before or have suggestions on what I might be missing?
Thanks in advance for your help!
You have a space after "BigTank "
It’s possible to rename the pool, but this requires first exporting it and then re-importing it in the command-line.
zpool import -R /mnt "BigTank " "BigTank"
cannot import 'BigTank ': no such pool available
Did you first export the pool? (This can be done from the GUI.)
Did it first on CLI but didn’t remount pool on reboot then retried the same operation on the GUI and it all went good! Had to fix the smb path share too…
Thanks Winnie! Didn’t know ZFS was cas-sensitive…
“Space” sensitive too. 
It’s good practice to only use letters, numbers, dashes, and underscores in ZFS pool and dataset names.
