I'm trying to do a simple zfs send/receive of a snapshot of zroot, but it seems to halt entirely when sending /usr/ports. What I did:
This is being sent to a 16GB flashdrive. Could it be predicting that I may not have enough space and silently failing and hanging?
zpool create zrootbackup -o altroot="/mnt/zrootbackup" /dev/da0 zfs create zrootbackup/servername zfs set readonly=on zrootbackup/servername zfs snapshot -r zroot@`formatting for date` zfs send -R zroot@today | zfs receive -dvuF zrootbackup/servername
