I'm trying to make a backup of a zvol before I try to resize it, (just in case). When I try to zfs recv, I consistently get the error:
cannot receive incremental stream: dataset is busy
I have tried both zfs send to a file and subsequent receive, and piping send and receive together.
I.e.
- Code: Select all
# zfs send -vceLR Wells/TM/Camel@2020-06-20 > Wells/TM/Camel-backup; zfs receive -Fv Wells/TM/Camel-backup < Wells/TM/Camel-backup
- Code: Select all
# zfs send -vceLR Wells/TM/Camel@2020-06-20 | zfs receive -Fv Wells/TM/Camel-backup
- Code: Select all
# zfs send -vceLR -I Wells/TM/Camel@2017-11-15 Wells/TM/Camel@2017-12-09 | zfs recv -Fv Wells/VMs/Camel-backup-2
