SELinux is preventing /usr/bin/sh from read access on the directory .

*****  Plugin catchall (100. confidence) suggests **************************

If you believe that sh should be allowed read access on the directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep sa1 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Should tell you the file being accessed along with the path.

Also, /dev/sda3 has no dir named root:

$ ls /sda3/root
/bin/ls: cannot access /sda3/root: No such file or directory
