Re: Data backup- (udev problem)

[Angelo Moreschini <mrangelo.fedora@xxxxxxxxx>]

Hi Samuel,

if I use fstab to mount permanently some partitions that I made on a USB Hard Disk, THEN, every time I use the "find" command, I get (from nautilus) requests to open (show) these partitions.

And this is not only an (very much) annoying problem..

In that eventuality I also begin  to have problems at the boot  ...
I not understand exactly because of this (I can only to think the problem is connected with the <udev> feature) ,
but for sure..  the problems completely disappear if I delete the permanent mounting of partitions with fstab.

================

here some line of command :  sudo journalctl  | grep -i PRTZ_programming (PRTZ_programming = name of partition I made on USB HD)

================l

I use the partitions on USB Hard Disk in order to do the back up of the data of the computer..
And now I am looking for an alternative method (solution) to mounting the partitions..

-----------------

another thing I would like to ask :

to use autofs for partitions on my USB HD that is permanently connected to computer,

it is mandatory install also NFS (network file system)  ???

-----------------

Thank you

Angelo

However, this solution for backing up the data is problematic, because _I always receive messages with the request of access to the partitions __of the “backup-partitions”__by "nautilus"_ - every time that I use the "find" command.

I don't understand this.  Can you provide more details about what is happening here?  I wonder if systemd is lazy mounting the drives, so they don't actually mount until you access them for the first time.  If you look in the journal, you should be able to tell by the timestamps when the drive gets mounted.
