Replication Tasks Erroring out

jhogan93 · November 29, 2022

hey guys, i built a new Truenas server and im trying to copy over my old dataset i followed this guide:

and all i get are errors.

i see on Truenas forums ppl complaining about the same issue but i cant seem to use their fix for my situation.

here is my error logs:

I/O error
pool or dataset is busy.

my old Truenas server is running Truenas core while my new Truenas server is running Truenas Scale (mostly for compatibility with 2.5gb network card Trendnet TEG-25GECTX)

thanks again!
