I’ve been noticing other posts where folk have LVM problems like this.
One is here, and @marcos-morar comments with links to older ones, even going back to a case with forced power off in july 2025 (maybe 4.2).
Some ideas/questions:
- suspend+hard shutdown is a frequent cause?
- specific hardware? - like some disk or controller write cache that tells lies about when data has been fully written, so strict ordering is not possible…?
- or only tired/worn disks?
- unlikely for LVM to have a bug giving such problems? - it seems such a problem should also show in normal Fedora and other Linuxes that use LVM. I looked for such reports, but did not find any big number yet…
- except if there is any special option or feature in Qubes use of LVM, or Xen underneath, that could cause it?
Maybe it is useful for people to tell what hardware they have, if they are comfortable - it could give a clue. Especially disk type and system/motherboard, but who knows what else might contribute?
And this ^^^ sounds useful.
What does everyone else think?
I am worrying about turning on suspend, because of it, and I need to decrease heat generation ! Btrfs is not tempting.
