Redis sentinel enter mode TILT when raid-check running?

-1

I'm using redis sentinel (Redis v3.0.7), everything is work fine. But 1:00 AM - 4:29 AM every Sunday in /var/log/sentinel.log have TILT mode entered:

4036:X 12 Nov 01:03:16.607 # +tilt #tilt mode entered

4036:X 12 Nov 01:03:46.622 # -tilt #tilt mode exited

4036:X 12 Nov 01:07:20.246 # +tilt #tilt mode entered

4036:X 12 Nov 01:07:50.401 # -tilt #tilt mode exited

.....

4036:X 12 Nov 04:29:13.825 # +tilt #tilt mode entered

4036:X 12 Nov 04:29:43.860 # -tilt #tilt mode exited

I checked at that time and I saw raid_check also running at same time:

cat /etc/cron.d/raid-check

Run system wide raid-check once a week on Sunday at 1am by default

0 1 * * Sun root /usr/sbin/raid-check

I don't know why.

From the docs:

However if the computer time changes in an unexpected way, or if the computer is very busy, or the process blocked for some reason, Sentinel may start to behave in an unexpected way.

Sounds like Redis is noticing that the server is under heavy load due to the RAID rebuild, and switching to tilt mode so it doesn't provide incorrect data, which is the desired behavior.
