I’m +1 on removing the default. While /opt/mesos may seem reasonable on the surface given many common uses of /opt, putting data there doesn’t really comply with FHS. Arguments could be made for /var/mesos (which I’m using) or /srv/mesos, but I think no default is fine.
I noticed early on that it was a little odd to default to /tmp, but felt as if I was following someone-or-other’s lead. It’s now clear that’s not the case. :) From: tommy xiao <xia...@gmail.com<mailto:xia...@gmail.com>> Reply-To: "user@mesos.apache.org<mailto:user@mesos.apache.org>" <user@mesos.apache.org<mailto:user@mesos.apache.org>> Date: Tuesday, April 12, 2016 at 11:14 PM To: "user@mesos.apache.org<mailto:user@mesos.apache.org>" <user@mesos.apache.org<mailto:user@mesos.apache.org>> Cc: dev <d...@mesos.apache.org<mailto:d...@mesos.apache.org>> Subject: Re: [Proposal] Remove the default value for agent work_dir how about /opt/mesos/ +1 2016-04-13 12:44 GMT+08:00 Avinash Sridharan <avin...@mesosphere.io<mailto:avin...@mesosphere.io>>: +1 On Tue, Apr 12, 2016 at 9:31 PM, Jie Yu <yujie....@gmail.com<mailto:yujie....@gmail.com>> wrote: +1 On Tue, Apr 12, 2016 at 9:29 PM, James Peach <jor...@gmail.com<mailto:jor...@gmail.com>> wrote: > > > On Apr 12, 2016, at 3:58 PM, Greg Mann > > <g...@mesosphere.io<mailto:g...@mesosphere.io>> wrote: > > > > Hey folks! > > A number of situations have arisen in which the default value of the > Mesos agent `--work_dir` flag (/tmp/mesos) has caused problems on systems > in which the automatic cleanup of '/tmp' deletes agent metadata.
