Hi all, Running Ubuntu 18 LTS, I have a console-mode number-cruncher which writes occasional output files. It works just fine if the output is directed to a drive which is permanently spun up, but can fail if the output is directed to a USB drive (by which I mean a USB-connected 8TB external drive, not one of the keydrives). I've followed things through with the debugger, and it seems that the problem occurs when the drive has powered itself down due to lack of accesses. The assign and rewrite work OK, but then the first attempt to write to the file fails with a 'No such file' error. Putting a large (30 second!) delay before the first write means everything works OK, presumably because the drive gets time to spin up again.
My question: Is there a standard method for handling this situation, i.e. making sure that a drive has not spun down, or is it just a case of writing a wrapper round the write function and handling the 'No such file' error with a wait and a retry? Thanks, Brian. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
