Would it be possible for LVM to support multi-operation transactions within a volume group? Qubes OS often needs to perform 3 LVM commands at once and doesn’t care about the order of the operations. It would also be nice to get the result of the system afterwards, to avoid needing a separate “lvm lvs” call. The purpose of this is to improve performance, by allowing device scanning, metadata access, and synchronizing with udev to happen once per batch instead of once per operation. I’m willing to promise that there are no dependencies between operations and that the operations can safely be performed concurrently. I also don’t need the overall operation to be atomic, so long as the system is always in a consistent state and any problems result in a non-zero exit code. Getting the result of the individual operations would be nice but is not required. I’m not sure what the best syntax for this would be. For the interactive shell, “begin” and “end” commands might be an option. -- Sincerely, Demi Marie Obenour (she/her/hers) Invisible Things Lab
