not mount my usb hard drive

Sun Aug 20, 2017 9:20 am

Hi,
I have in root cron:

Code: Select all

@reboot mount  -o uid=pi,gid=pi /dev/sda1 /home/pi/folder/ 

Always works to me but for some time not works.
Someone could help me please?

Thanks and sorry for my English!

Do you have more than one USB storage device connected? If so, the device node (/dev/sda...) may change across reboots.

You may get better results mounting by UUID. You can get that from running

Code: Select all

sudo blkid
You might also want to switch from using cron to using an entry in /etc/fstab and letting the system take care of mounting it.
Attempts to contact me outside of thes forums will be ignored unless signed in triplicate, sent in, sent back, queried, lost, found, subjected to public enquiry, lost again, and finally buried in soft peat for three months and recycled as firelighters

Even better than an /etc/fstab entry is a systemd xxx.mount file.

Create /etc/systemd/system/home-pi-folder.mount

Code: Select all

[Unit]
Description=Mount /home/pi/folder directory
#
# Replaces this line in fstab
#/dev/sda   /home/pi/folder  vfat defaults,noatime,x-systemd.automount,uid=pi,gid=pi 0 0
#
[Mount]
What=/dev/sda1 # CHANGE ME to value from blkid if available
Where=/home/pi/folder
Type=vfat  # CHANGE ME if /dev/sda1 isn't formatted at VFAT
Options=defaults

[Install]
WantedBy=network-online.target
enable that with sudo systemctl enable home-pi-folder.mount
get it active for this boot with sudo systemctl start home-pi-folder.mount
