No, you don't need to do any of that. Just executing volume-set commands is sufficient for the changes to take effect. -Krutika On Wed, Jun 21, 2017 at 3:48 PM, Chris Boot <bootc at bootc.net> wrote: > [replying to lists this time] > > On 20/06/17 11:23, Krutika Dhananjay wrote: > > Couple of things: > > > > 1.

This is all coming from the CentOS Storage SIG's centos-release-gluster310 repository. Thanks again. Chris -- Chris Boot bootc at bootc.net

The home-made UPS can run those devices on the same batteries as my 230V UPS, but last for several hours rather than a few minutes due to increased efficiency. The microcontroller I'm using has a serial

They have installed a wireless link and I have made certain that put it behind my simple iptables
