After rebooting an ESXi guest, sometimes my NFS storage will no longer be visible to the system. Upon trying to re-add the storage to the ESXi host, it will error. To easily fix this issue, we will need to access the ESXi hosts CLI.
Ran into an issue this morning while changing some network switch ports around where all of a sudden vMotion was no longer working. I did not change the VMware configuration, only the ports in which they were plugged into.
Moving some storage around this evening created a situation where my primary VM datastore was imported on one of my hosts with a new signature file. This had repercussions on the other host in the cluster, causing a situation where when the datastore was being detected through the iSCSI adapter, but not being displayed in the storage window. If the storage was manually added through the vSphere GUI, it would only allow a reformat.
CLI to the rescue.
Updating to ESXi 5.5 was a pretty straightforward task overall. One of my ESXi hosts upgraded without any complications. The second host hung during “relocating modules and starting up the kernel” of the initilization of the installer.
The storage that is running blog.destephen.com is a product of several iterations of lab Network Attached Storage (NAS) setups. What it developed into today allows storage and playback of 1080i home videos, bulk storage of personal files, as well as running 30+ VM’s on a daily basis. This post, while long, walks through the some features and through processes along the way of designing the 21 disk, 25 TB system.
