zfs send and receive does not finish

[nas4free-user]

I try to move datasets from XigmaNAS to Freenas by:
zfs send pool/dataset@snapshot | ssh destination-IP zfs receive -F dpool/dataset1/received-dataset

everything is fin for small datasets (100GB), but when trying with > 1TB, anytime (after > 100 GB) I get a
"connection closed by remite host" error all transfered data are being deleted.

How can I monitoring whats going on on FreeNAS?
Can I log anything during thr transmission?

How short is your snapshot interval?

Snapshotintervall is daily, but I did a manual snapshot for the transfer!

 

[sretalla]

could it be the case that the daily snapshot runs while the larger transfer is still running?

Test with rsync --av --progress <source> <destination>, to see if you can transfer the files.

Actually, I shifted from rsync to sednd & receive snapshots for performance reasons!
I'm going to disable automatic snapshots and try again!

Problem solved!
After I disabled the automatic snapshot for the dataset to be transferred, everything went fine!
Probably, it must not be taken a newer snapshot while transferring an existing snapshot!?

This was the case! Thanks for the hint.
