20.59. kb-00058: Image Deploy with Curtin Partitions and XFS¶
20.59.1. Knowledge Base Article: kb-00058¶
20.59.2. Description¶
When doing image-deploy, there are a couple of errors that can be generated when using XFS. These include:
grub-install fails because of bad filesystem type
Missing / bad rootfs or other filesystem on reboot into running system.
This can happen when using Sledgehammer to image deploy Centos 7 or Ubuntu 18.04 or younger images.
The problem is that Centos 8 has a newer version of XFS that is incompatible with the XFS running in previous operating systems, e.g. Centos 7 or Ubuntu 18.04.
This happens when a curtin/partitions parameter is used that sets an XFS filesystem. This is NOT the default and so is only triggered from this action.
20.59.3. Solution¶
Within curtin/partitions parameter, an additional variable will need to be added to all XFS filesystem creation stanzas. This looks like this (in JSON format):
"extra_options": [ "-i", "sparse=0" ],
This tells the Centos8-based sledgehammer to generate an XFS filesystem that will work in the older environments.
A complete XFS filesystem stanza would look like this:
{ "extra_options": [ "-i", "sparse=0" ], "fstype": "xfs", "id": "disk0-part1", "label": "root-partition", "type": "format", "volume": "root_part" }
You will also need to make sure that your image contains the XFS tools. If you are using image builder, you can use the image-builder/additional-packages parameter with a value that includes xfsprogs.
