Outlook Style Google Calendar Notifier

So I moved to a GSuite company. What did I get myself into? I can deal with the browser based apps. That’s fine. It’s the calendar notifications. I don’t see them. I don’t hear them. They are so unobtrusive I miss meetings. I need my old Outlook popup windows. I am old. I admit it.…

WiFi Art

A while ago I saw this project from rootkid called Spectrum Slit https://rootkid.me/works/spectrum-slit. I thought it was really cool. I showed it to a bunch people because I really liked the idea. Now if you know me or have read any of my drivel here you know I can’t leave things alone when I see…

Inside Proxmox’s LVM Snapshot Chains

For years, virtualization admins have mentally separated storage into a few neat buckets: Storage Type Snapshot Method qcow2 on filesystem qcow2 backing chains/internal snapshots ZFS Native CoW snapshots VMware VMFS Delta VMDK chains Then Proxmox decided to make things weird. Recently I started digging into Proxmox’s experimental snapshot-as-volume-chain functionality for LVM storage and quickly realized…

Your Snapshots Aren’t the Problem. Your Restore Process Is.

I built a platform for restoring Proxmox VMs from Pure Storage snapshots. The storage part was easy. Fixing the workflow was the real engineering. TLDR: GitHub – PureStorage-OpenConnect/proxmox-pure-snap-restore: A utility to allow restoring Proxmox LVM based VMs from FlashArrary snapshots · GitHub There’s a familiar enterprise fairy tale: “We have snapshots.” Everyone nods. Risk has…

So you want to restore a Proxmox VM from an array snapshot?

Maybe some duct tape? I know I’ve done it too. Everything untested just have the data somewhere and some hope that you can…

lvm and xcopy

Does anyone else remember when XCOPY via VAAI was released on vSphere? How cool it was to offload the copy of a VM to the array. It only got cooler as the storage vendors figured out how to not actually need to copy the data but just point to the data. Clones went from having…

Proxmox Multipathing Storage Plugins

For those of us who have been around long enough multipathing in VMware environments has just been a thing that has worked. FC or iSCSI you knew what you had to do. iSCSI needs port binding and multiple initiator IPs. FC needs multiple HBAs and paths. It just became a way of life to configure…

Pure vVOLs Migrations From vSphere To Proxmox

I told you there were a few more of these. I was talking to my new manager Paul about some of the things that need to be documented. One of the items was what can Pure do from a migration perspective that others can’t. He mentioned a tool we use to do migrations and that…
