Description of problem: My RAID1 suddenly disappeared. A restart didn't resolve the issue. So i ran $ sudo mdadm --assemble --scan and this alert went off. SELinux is preventing mdadm from 'search' accesses on the directory /sys/firmware/efi/efivars. ***** Plugin restorecon (99.5 confidence) suggests ************************ If you want to fix the label. /sys/firmware/efi/efivars default label should be sysfs_t. Then you can run restorecon. Do # /sbin/restorecon -v /sys/firmware/efi/efivars ***** Plugin catchall (1.49 confidence) suggests ************************** If you believe that mdadm should be allowed search access on the efivars 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 mdadm /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:mdadm_t:s0-s0:c0.c1023 Target Context system_u:object_r:efivarfs_t:s0 Target Objects /sys/firmware/efi/efivars [ dir ] Source mdadm Source Path mdadm Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-155.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.6-300.fc23.x86_64 #1 SMP Tue Nov 10 19:32:21 UTC 2015 x86_64 x86_64 Alert Count 180 First Seen 2015-12-01 19:13:22 CET Last Seen 2015-12-01 19:13:23 CET Local ID cfabbc1c-55bd-409d-8bd9-9b92650cc2f1 Raw Audit Messages type=AVC msg=audit(1448993603.65:896): avc: denied { search } for pid=22978 comm="mdadm" name="/" dev="efivarfs" ino=11339 scontext=system_u:system_r:mdadm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:efivarfs_t:s0 tclass=dir permissive=0 Hash: mdadm,mdadm_t,efivarfs_t,dir,search Version-Release number of selected component: selinux-policy-3.13.1-155.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.6-300.fc23.x86_64 type: libreport Potential duplicate: bug 1276519
