Hi Vaibhav, Just go through this blog; it seems the two slave using different work directory (/tmp/mesos1 and /tmp/mesos2) Regarding your log, your work directory is --work_dir="/home/introom/work/mesos/work_dir"; did you change the work directory of the both slaves?
And if you have updated slave's configuration, e.g. resources, you'll also get similar issue when restarting. There's a JIRA (MESOS-1739) to support re-configuration when re-starting slave. ---- Da (Klaus), Ma (马达) | PMP® | Advisory Software Engineer Platform Symphony/DCOS Development & Support, STG, IBM GCG +86-10-8245 4084 | klaus1982...@gmail.com | http://k82.me On Wed, Jan 13, 2016 at 4:04 AM, Vaibhav Khanduja <vaibhavkhand...@gmail.com > wrote: > Tried something similar here, > http://veekeay.blogspot.com/2016/01/fine-grained-resource-management-using.html > > On Tue, Jan 12, 2016 at 5:19 AM, Klaus Ma <klaus1982...@gmail.com> wrote: > >> The default behaviour it to report all cpu/mem; but there's a >> module/plugin to report resources on demand, please refer to MESOS-3366. >> And as haosdent said, you can also use container for that.
