Creating an IPv6 tunnel in Fedora Recently I had to access a server that only had an IPv6 address. As I am one of the over 80% of the UK without IPv6 access I needed to set up a tunnel on my machine to do this.

Recently we had one of our Proxmox machines suffer a failed disk drive. Thankfully, replacing a failed disk in a ZFS zpool is remarkably simple if you know how. In this example, we are using the ZFS configuration as per the Proxmox installer which also creates a boot partition which is not part of the zpool. Seems like a pretty sensible idea to me. Here is how we can look at the status of our zpool and see that it has a failed disk: root@cluster1 zpool status -v pool: rpool state: DEGRADED status: One or more devices could not be used because the label is missing or invalid.

When trying to update a Magento 2 database recently using: php bin/magento setup:upgrade I also tried: php bin/magento setup:upgrade --keep-generated I got the following error: [Exception] Warning: file_get_contents(.../var/di/setup.ser): failed to open stream: No such file or directory in .../vendor/magento/framework /App/ObjectManager/ConfigLoader/Compiled.php on line 28 It looks like a regression was introduced in 2.1.0 that stops you running setup:upgrade after running setup:di:compile. A temporary fix for this is to remove all contents from var/di and var/generation, run the update and then re-compile.
