Does not detect hotplugged storage device

[themusicgod1]

I plug it in, it doesn't automatically mount, is not visible in nautilus. Mounts fine on system start up.

Similar problem for me - upgraded from Kubuntu 14.04 to 14.10 to 15.04 beta2 yesterday, plugging in HDD, not showing up in device manager.
syslog gets this upon plugging in:

HDD doesn't show up in /dev/sd*

[Martin Pitt (pitti)]

Friedemann, your problem is different. If /dev/sd* does not show up, then this is a kernel or hardware bug.

[Martin Pitt (pitti)]

themusicgod1: Can you still reproduce this? If so, can you please do this:

   udevadm monitor -e

then plug in the drive, and wait a few seconds. Please copy&paste the entire output here.

After that, please do

  udevadm info --export-db > /tmp/udevdb.txt

and attach /tmp/udevdb.txt.

Thanks!

[themusicgod1 (themusicgod1)]

If anything it's gotten worse: it used to be on restart, if the drive was plugged in, it would be detected whereas if I plugged it in it would not, now even on restart it's not detected. Mounting manually works just fine.

root@Hedy:/home/themusicgod1# udevadm monitor -e
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

Still issue in 15.10 wily werewolf.

[TJ (tj)]

Came across this bug looking for another issue. Some observations:

There is no information in this report of the file-system type. It is file-systems not partitions or devices that are mounted, so any problem with an unclean file-system could prevent it being auto-mounted.

The partition looks to use the entire 4GB so any fsck on a file-sytem within it would take a long time before an auto-mount could occur.

[TJ (tj)]

What does this report?

$ sudo lsblk /dev/sdb1

Also, is there an entry referring to it already, possibly with noauto option?

$ cat /etc/fstab

I'm wondering if you are effected by the mirror side of the issue I was researching.

In my case systemd is insisting on trying to mount non-existent hot-plug storage devices at boot-time. The external storage is connected via ExpressCard/SATA controller. At some point systemd added entries for the encrypted partitions, LVM VGs, and file-systems into its generator targets, and now at every boot waits for a long time waiting for those devices to appear.

$ ls -l /var/run/systemd/generator/

So far I've not found out how to safely disable those generator targets, or how to prevent them being created in the first place.

I wonder if your system has similar targets configured not to mount the file-system, or no targets at all?

I've since bought about 4 more 4TiB storage devices that all have the same issue(different manufacturers (?))

[Dimitri John Ledkov (xnox)]

As far as I understand big hard-drives are not automatically mounted - but should be present as partitions to mount via nautilus. E.g. I would not expect 4TiB drives to automount.
Automatically mounted are only flash-usb sticks.
