Can't execute scripts to which I have execute rights [SOLVED]

I have a directory ~/bin, in which I keep a couple of bash and sh scripts I use often. When I converted my disk from MBR to GPT I copied these files along with all files in my home to another disk, and afterwards I put them back using

rsync --progress -vrl --update -e "ssh -i ~/.ssh/mykey" /mnt/backup/archbox/home/me me@archbox:~/

Then all the files were back in my home, but when I try to execute the scripts, I get this error:

me@archbox ~/bin> ./flac2mp3
bash: ./flac2mp3: Access denied

Even though:

me@archbox ~/bin> ls -ln flac2mp3 
-rwxr-x--- 1 1000 1000 89 28 apr 12:01 flac2mp3*

which is my user id:

me@archbox ~/bin> id me
UID=1000(me) GID=1000(me) groups=1000(me),90(network),998(wheel)

When I start the scripts using

me@archbox ~/bin> bash flac2mp3

they run fine though.

Does anyone know what I'm missing here?

Thanks for any help!

Please post the output of the following:

stat ~/bin/flac2mp3
sed 1q ~/bin/flac2mp3
findmnt -T ~/bin/flac2mp3

Trilby,
What are you looking for in that sed command?  I get the other two.

I'm looking for precisely what it does: it shows the first line and thus it should have the shebang.

Please post the output of the following:

stat ~/bin/flac2mp3
sed 1q ~/bin/flac2mp3
findmnt -T ~/bin/flac2mp3

me@archbox ~> stat ~/bin/flac2mp3

TARGET SOURCE    FSTYPE OPTIONS
/home  /dev/sdc1 ext4   rw,nosuid,nodev,noexec,relatime,sync,data=ordered

It differs from the output of the last command.
The last line puzzles me, since:

me@archbox ~> grep -A1 "sdc1" /etc/fstab 
# /dev/sdc1
UUID=3acfd832-1761-45f8-9b34-24810195172e	/home		ext4		rw,auto,user,sync	0 1

It differs from the output of the last command.

/home  /dev/sdc1 ext4   rw,nosuid,nodev,noexec,relatime,sync,data=ordered

Post your /etc/fstab.  You are configured to not permit execution of stuff on that volume

/home  /dev/sdc1 ext4   rw,nosuid,nodev,noexec,relatime,sync,data=ordered

Yes, I saw that, but since it is not specified in my /etc/fstab, why is it there and how do I remove it?

Re: Can't execute scripts to which I have execute rights [SOLVED]

       user   Allow an ordinary user to mount the filesystem.  The name of the
              mounting user is written to the mtab file  (or  to  the  private
              libmount  file  in /run/mount on systems without a regular mtab)
              so that this same user can unmount the filesystem  again.   This
              option  implies  the  options  noexec, nosuid, and nodev (unless
              overridden  by  subsequent  options,  as  in  the  option   line
              user,exec,dev,suid).

Thanks!
