This seems to be exacerbated when there is limited free space on the /boot filesystem. HPE is no longer providing new firmware fixes for this platform. [Test Case] Install a new kernel and reboot. When this bug is triggered, you'll see the following errors (emphasis <<>> mine): ## Executing script at 4004000000 11349894 bytes read in 312 ms (34.7 MiB/s) <<invalid extent block>> ## Booting kernel from Legacy Image at 4002000000 ... Image Name: kernel 5.8.0-25-generic Created: 2020-10-21 5:26:34 UTC Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 11349830 Bytes = 10.8 MiB Load Address: 00080000 Entry Point: 00080000 Verifying Checksum ... OK Wrong Ramdisk Image Format <<Ramdisk image is corrupt or invalid>> [Where Problems Could Occur] The workaround I've added here is to attempt to defrag the boot files so that the u-boot parsing bug is not triggered. This workaround is only activated for machines tagged with a certain property, and only the m400 server is tagged w/ that property. If there is a bug in detecting the platform or property, it could of course impact other platforms. Though it should be said that this code uses a well-established flash-kernel pattern. On the m400, the code only implements the workaround if /boot is on an ext4 filesystem (the Ubuntu default). If the filesystem detection code is buggy, we may unintentionally run e4defrag on a non-ext4 filesystem which could cause errors. Those errors currently only cause a warning to be printed - it does not fail the script. Users who miss this warning could still end up with an unbootable system if the workaround fails -- which it may, if the disk is very close to full. Long term, we should consider making this error fatal.
