• Hot-Swap Failure After 6.7.2 update

    After the latest stable release 6.7.2 Hot-Swap does not work.

     

    Example.

     

    Added another drive into an available drive bay but the drive does not show up in Unassigned_Devices. (see 1st image)

    Rescaned from terminal:  rescan_scsi_bus (see 2nd image)

    Drive now shows up as an Unassigned_Device (see 3rd image)

     

    Additional information: I also tried to uninstall Unassigned_Devices and Re-install and that did not work either.

     

    The only other thing that worked was to [ REBOOT ] the server which also immediately displayed the missing drive.

     

    Could it be that there is an issue with hot-swapping drives and auto repolling/scanning for changes in the SCSI subsystem?

     

    If anyone is having this issue where drives are not showing up when swapped into your server, REBOOT or run command rescan-scsi-bus from the terminal. Note: @testdasi was kind enough to provide the later remedy.

     

    Any additional method of a permanent fix would be appreciated.

    No access to hot-swap drives unless REBOOT or manual RESCAN via terminal rescan_scsi_bus   /  Rescan button also does not work.

    Hot-swap is still working normally for me on v6.7.2, not saying there isn't a problem, but it might be limited to a specific controller or other hardware, you should post the diagnostics showing the problem, if nothing else we can see the hardware used.

    Just to state that it is also working for me, so although it does sound like a problem on the OP system it is not one that everyone is experiencing.    Posting diagnostics taken just after the system has failed to recognise a hot-swapped drive might help pin down the cause.

     

    there is also the fact that as far as I know Unraid has never formally supported hot swap although it seems to work fine when using the UD plugin the vast majority of the time.
