analytics1038 seems to have an issue with the BBU, alarms keep flapping:
08:38 <icinga-wm> PROBLEM - MegaRAID on analytics1038 is CRITICAL: CRITICAL: 13 LD(s) must have write cache policy WriteBack, currently using: WriteThrough, etc.. 08:48 <icinga-wm> RECOVERY - MegaRAID on analytics1038 is OK: OK: optimal, 13 logical, 14 physical, WriteBack policy
I forced a manual re-learn with sudo megacli -AdpBbuCmd -BbuLearn -aALL -NoLog but it doesn't seem to have reached the desired result:

The host is OOW, but if we have a spare BBU in the DC we might attempt a swap.
