Replication Task Fail "zfs destroy"

TrueNAS General
1

Complete newbie here. I have a replication task setup to replicate another drive. I get the below error when trying to run the task. Following the error I try to run the “zfs destroy -r Fire Control Center LGM@auto-2025-11-30_00-00"

I get “root@truenas[/mnt/Thunderball/sgtmass]# sudo zfs destroy -r Fire Control Center LGM@auto-2025-11-30_00-00
too many arguments
usage:
destroy [-fnpRrv] <filesystem|volume>
destroy [-dnpRrv] <filesystem|volume>@[%][,…]
destroy <filesystem|volume>#

For the property list, run: zfs set|get

For the delegated permission list, run: zfs allow|unallow”

I am not able to delete the replication error and start a new replication task.

If you have a command argument that contains spaces you need to quote it. In this example, zfs destroy -r "Fire Control Center LGM@auto-2025-11-30_00-00" would be better. However spaces aren’t allowed inside in ZFS component names, so I don’t think that would work.

I don’t know how you managed to get to this point. What dataset are you trying to replicate? How did you get a name with spaces inside?

I have two 16 TB drives that I have previously replicated to another set of 16 TB drives. The file drives/replication task is “Fire Control Center LG” - “Fire Control Center LGM” I have replicated this way without errors for about 6 months until I had a boot drive failure. After reinstalling and setting the replication back up, I get the replication error. I’m assuming a permission issue developed somewhere after reinstall. So I just want to delete the dataset and start the replication again, but I want to understand how to do this and/or why this happened.

Can you check the replication settings and make sure that source and destination are correct? There shouldn’t be any spaces in the names.

EDIT: The file /var/log/zettarepl.log contains more log messages about replication which might be helpful.

Ok so I ran zfs destroy -r “Fire Control Center LGM@auto-2025-11-30_00-00” that worked. I then had another error and also had to run zfs destroy -r “Fire Control Center LGM@auto-2025-11-23_00-00” as it was complaining about that one after.

Once I run the zfs destroy on the second dataset it appears to be running as of now without error. I’ll post back after it completes.

I guess OpenZFS does allow spaces. Spaces do have a tendency to break a lot of scripts. So be careful with properly quoting your arguments.
