Installed from default ubuntu repository. What does "-W" do?

[cronnelly]

I've packaged the latest version of mbuffer for Ubuntu Trusty, to solve this issue. It's available via our PPA:

https://launchpad.net/~clock/+archive/ubuntu/mbuffer

[redmop]

Also, it works fine if you edit /opt/znapzend-0.14.1/lib/ZnapZend/ZFS.pm and remove the -W from the mbuffer line

has mbufferParam => sub { [qw(-q -s 128k -m)] }; #don't remove the -m as the buffer size will be added

in 14.04

[hadfl]

-W option was added in mbuffer version 20121111
