ZFS Replication from FreeNAS to OS X

[henningkessler]

Hello,

I am trying to set up a replication task from a FreeNAS server to an OS X server. Everything is working except the lz4 compression.

This is the error messages from the FreeNAS host:

Code: Select all

May 25 12:04:01 SNDHOST autorepl.py: [tools.autorepl:138] Sending zfs snapshot: /sbin/zfs send -V tank01/shares@auto-20160518.1300-1w | /usr/local/bin/lz4c | /usr/local/bin/throttle -K 20000 | /bin/dd obs=1m 2> /dev/null | /bin/dd obs=1m 2> /dev/null | /usr/bin/ssh -i /data/ssh/replication -o BatchMode=yes -o StrictHostKeyChecking=yes -o ConnectTimeout=7 -l sadmin -p 22 RCVHOST "/usr/local/bin/lz4c -d | /sbin/zfs receive -F -d 'backup' && echo Succeeded"
May 25 12:04:02 SNDHOST autorepl.py: [tools.autorepl:157] Replication result: bash: /usr/local/bin/lz4c: No such file or directory

Is there a lz4c binary in OS X so i could create a symbolic link to /usr/local/bin/lz4c?

Regards

Hi Brendon,

thanks for your answer, but as O3X utilizes the lz4 compression as a flag for pools lz4 must be already baked into the system or installed by O3X..

or am I wrong with that?

Its in the kernel. You are asking for a userspace utility which we don't have. I think you are getting that utility from your OS, rather than your ZFS implementation.
