A system can determine to uninstall a patch that is installed on a computer, wherein an image of an operating system of the computer and a package that was used to install the patch are cryptographically signed. The system can further identify a first stored location of the package, and a second stored location of the image of the operating system. The system can further extract a file manifest from the package at the first stored location. The system can further extract versions of files identified on the file manifest from the image of the operating system at the second stored location, resulting in extracted versions of files. The system can further store the extracted versions of files to a temporary storage location. The system can further move the extracted versions of files in the temporary storage location to respective original running locations of the versions of files.

Patch uninstallation using a signed operating system install package

Techniques are provided for installing patches during upgrades. In an example, an administrator specifies an upgrade image and a patch for a computing cluster. The computing cluster verifies compatibility between the upgrade image and the patch, registers the patch, and stores the patch for later use at the cluster level. Then, at the node level, the upgrade image and the patch are applied to each node that is upgraded.

Installing patches during upgrades

Techniques are provided for installing patches using a jail. In an example, a computing node boots from a first partition and then mounts a second partition. The computing node can install an upgrade image for an operating system on the second partition. The computing node can then create a jail that sets the mount point of the second partition as the apparent root directory, and install one or more patches within the jail. The computing node can then reboot from the patched and upgraded operating system of the second partition. In this manner, the node can be upgraded with an operating system and one or more patches, while being rebooted once.

Installing patches using a jail

Performing patch reconciliation of storage nodes within a storage cluster is presented herein. A patch reconciliation component receives an upgrade patch request to upgrade a first version of an operating system (OS) on a data storage node of a data storage cluster to a second version of the OS that has been installed on another data storage node of the data storage cluster, the first version preceding the second version; and based on the upgrade patch request, determines a group of upgrade patches to apply to the first version of the OS to facilitate the upgrade, and applies the group of upgrade patches to the first version of the OS resulting in the upgrade of the first version of the OS to the second version of the OS, the group of upgrade patches comprising respective upgrade binary files for the first version of the OS.
