After a fashion the number makes some sense: The small swap partitions are 2 GB, if the swap is used uniformly the total would be 8 GB. 7192 MB is less wrong than the ~13GB reported by swapinfo. > > You might want to report the types/models of the USB flash devices that > were in used.

One is model SDCZ80-064, the other SDCZ800-064. The former is rated USB3.0, the latter USB3.1. They're certainly not new, but neither are they obviously broken (yet). Thanks for reading! bob prohaska
