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

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!
