Let me add this which I failed to mention.

This was a fresh install as a "Server with Desktop". I have been adding
packages as needed.

Week before last when working on this, I was looking through the logs and
found REAR need syslinux which wasn't installed. I may not have all the
packages installed I need. I run REAR as a cron job around 2AM. If I did a
reboot/restart and forgot to manually mount the USB drive or forgot to click
on it gnom, which is usually the case, I don't get a backup.

It ran last night and I was OK, but I'd still need to find out why its not
mounting by itself.

Thanks

Seems a permission issue.  su to root after the "auto" mount and take a
look.  If you can see your file or can write a touch file then your user
may not be in the necessary owner/group to view/write to the structure.
Seen similar problems in upgrades... same user but the UID changed in the
upgrade and blinded the current user to older files that were preserved.  A
simple chmod command from root fixed the issue to restore proper
ownership.  Just a wag, but sometimes it's the little things.

I've never had to do anything at all to make this work,...
I insert the USB device, wait a few seconds, and voila!

are you trying this because you can't get it to work the "normal" way,
or is this simply an educational experience?

Fred

Its not mounting on its own as it did in 6.8.

If I click on it in gnome, it mounts but REAR won't backup to it.

If i manually mount it from a terminal, I have read/write access.

Haven't been able to get a backup since I upgraded back in mid-January.

[CentOS] Automounting a USB drive

[tdukes]

Hello,

Been try to use autofs to mount and unmount a usb flashdrive.

The mount point is /media

When the drive is NOT inserted, /media is empty. When Iinsert the drive,
I see directories in /media that are on the usb drive but nocontent.

So, its kind working.

/etc/auto,master:

#
# Sample auto.master file
# This is a 'master' automounter map and it has thefollowing format:
# mount-point [map-type[,format]:]map [options]
# For details of the format look at auto.master(5).
#
/misc /etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted withthe
# "nosuid"and "nodev" options unless the "suid" and "dev"
# optionsare explicitly given.
#
/net   -hosts
#
# Include /etc/auto.master.d/*.autofs
# The included files must conform to the format of thisfile.
#
+dir:/etc/auto.master.d
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
+auto.master

/media   /etc/auto.usb

/etc/auto.usb:

usb-fstype=auto:/dev/sdb1

The particular usb drive is a REAR backup drive but Iused -fstype=auto
in case it may be something different.

TIA
