sqlinux weirdness

Every now and then I get an alert like this one. I have no clue what this
"rear" subsystem is, or why madam would be trying to write to its log
file.

Can anyone enlighten me?

thanks in advance!

SELinux is preventing /usr/sbin/mdadm from write access on the file /var/log/rear/rear-fcshome.log.lockless.

***** Plugin restorecon (93.9 confidence) suggests ************************

If you want to fix the label.
/var/log/rear/rear-fcshome.log.lockless default label should be var_log_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /var/log/rear/rear-fcshome.log.lockless

***** Plugin leaks (6.10 confidence) suggests *****************************

If you want to ignore mdadm trying to write access the rear-fcshome.log.lockless file, because you believe it should not need this access.
Then you should report this as a bug.
You can generate a local policy module to dontaudit this access.
Do
# ausearch -x /usr/sbin/mdadm --raw | audit2allow -D -M my-mdadm
# semodule -i my-mdadm.pp

***** Plugin catchall (1.43 confidence) suggests **************************

If you believe that mdadm should be allowed write access on the rear-fcshome.log.lockless file 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:
# ausearch -c 'mdadm' --raw | audit2allow -M my-mdadm
# semodule -i my-mdadm.pp

ReaR is Relax-and-Recover tool: <a href="http://relax-and-recover.org/" title="http://relax-and-recover.org/">http://relax-and-recover.org/</a>

It creates a bootable CD/DVD with all backup content to restore your system.

Try to restore SELinux label to see if that would help.

OK, did that. we'll see what happens, thanks!

Reading back thru my original I can only guess that I needed sleep,
given the (at least) two horrid typos: sqlinux==>selinux, and madam==>mdadm.
ugh.

thanks again!
