Linux 101: Disown long running jobs like an InsightIQ database upgrade

Long InsightIQ upgrade processIf you’re remotely managing a Linux machine, you’ll probably use an SSH connection to run commands on that machine. There’s one problem with this approach: if you close the SSH connection, any long-running jobs/commands will halt. If you know a job will take a long time and you won’t be able to babysit the SSH connection, you can plan accordingly. But what if you underestimated the time a job will take, and you need to disconnect anyway? Here’s how to keep the job running AND make it home in time for dinner!

Linux 101: Extend root partition of an InsightIQ VM

InsightIQ old free spaceWhile upgrading OneFS it’s important to keep the InsightIQ software version compatible with the Isilon systems. In this case, InsightIQ wasn’t updated for a while and I had to upgrade from 3.0 -> 3.1 -> 3.2 -> 4.x. The actual upgrade process isn’t too hard (it just takes a lot of time), but there’s one little prerequisite in the 3.1 -> 3.2 upgrade: a minimum free space in the root partition of 502MB. As you can see in the screenshot, I wasn’t even close to the minimum requirement. I got to 357 MB, and that’s after cleaning up redundant stuff. Time to add some more disk space and extend root partition!

Dell EMC World 2017 recap: “Cloud is not a place; it’s a way of doing IT” and “AI is here to stay”

DellEMCWorld 2017 logoThis is a long overdue post covering Dell EMC World 2017 in Las Vegas and the announcements that were made during the event. I’ll recap some of the topics that resonated most with me, namely that cloud computing is not a place but a way of doing IT. Secondly, I spoke briefly with some of the Dell EMC server guys whom give me hope that the Dell 14th generation servers are a big step up from previous experiences. Finally, I’ll share a bit of insight in what the Dell EMC Elect picked up during an interview with John Roese, and will link to a few posts from friends that attended Dell EMC World 2017. Maybe it’s a bit more of a “Dear diary,”-style post, so hang in there.

VNX Unified standby data mover interface suspended after Cisco NX-OS upgrade

We’re in the midst of a VCE vBlock 340 software upgrade. Part of this upgrade process is upgrading the Cisco Nexus 5K switches that connect the blades and storage to the customer network. After upgrading the switch we suddenly noticed on the switch that the VNX Unified standby data mover (server_3) interface suspended with a “no LACP PDUs” error message. A quick check on the switch that wasn’t upgraded yet showed that interface to be online. So what’s up with that?

VNX Unified upgrade – Where’s that .upg package?

VNX OE for File .upg package selectionA VNX Unified upgrade is fairly easy: Unisphere Service Manager (USM) does most of the heavy lifting. A Block only system is the simplest of all: you upload a .ndu software package to the system and wait for the update to complete.

A Unified system is a combined package of a VNX Block system, and a File component consisting of one or two Control Stations and at least 2 datamover blades. In a VNX Unified upgrade, you first need to upgrade the File part of the system and afterwards the Block part. For the File upgrade, you need to select an .upg package. But… you can’t download this from the EMC/VCE website. Now what?

Workforce Transformation at Dell EMC World 2017

DellEMCWorld 2017 logoOn the first day of Dell EMC World 2017 in Las Vegas a few important announcements were made. It covered both product announcements and other industry developments. I’ll try to cover a few that stood out to me, and how they will impact the people that run the IT infrastructure. This workforce transformation as Dell EMC calls it, might be more challenging than simply making a system a bit faster with flash.
