Hello! I have an issue re-gaining access to my data. The error messages are: # lvchange -ay ernie/system Check of pool ernie/cache failed (status:1). Manual repair required! # lvconvert --repair ernie/system bad checksum in superblock Repair of cache metadata volume of cache ernie/system failed (status:1). Manual repair required! How do I recover from this situation and repair the volume group? For a full log, including the output of pvdisplay, vgdisplay and lvdisplay -a, please see attached log file. If more information is necessary, please ask. What led to this situation: I am using one of the infamous AMD Ryzen 2400G with an AMD B350 chipset, which suffers from random lockups related to CPU C-states [1]. With the recent AGESA 1.0.0.2a firmware update and the introduction of the "Power Supply Idle Control = Typical Current Idle" setting, the system is stable, if it boots at all. But it often takes several attempts to boot -- the failed attempts ending in weird firmware / EFI or CPU / idle related Linux kernel stack traces, which sometimes even require a hard reset, since soft-reboot (ctrl+alt +del) sometimes has no effect, because init dies. This was such a situation, where I had to reboot (ctrl+alt+del) and reset (hard) the system several times, at the end of which everything seemed fine, except that dracut was timing out when activating the disks. Debugging the situation using a Fedora 28 live system resulted in the attached log file. --Dennis [1]: https://bugzilla.kernel.org/show_bug.cgi?id=196683
