Hello all,Sad news: cfarm420~430 except cfarm423 are down. Today I had to shutdown almost all servers at home because the room temperature was rising to 34 degrees and became too unbearable, and BMC keeps sending me so many alerts. The air conditioning is working very hard but not sufficient. After a few hours, I booted some of them back online, but cfarm420..422,430 are still down, because the HBA is probably dead (overheat?) (the drives themselves and the SAS expander are probably OK).
cfarm424..429 will be back online in a jiffy, once the room temperature is back to 28 degrees. As for cfarm420..422,430, until I replace the HBA or find a way to reroute(?) the drives, they will be down and stay down for an unknown period of time. I apologize for the inconvenience.
Clearly I need a long term solution to the overheating issue. Apparently I have too many servers at home. Swapping the air conditioner for a more powerful one is a no-go because my landlord would not do it. But fortunately, related to my personal life and news, I plan to buy a home soon, I'll personally pick out the best air conditioner units, and it will be the permanent home for those servers. But until then, until the servers are moved to a new home (not later than the end of this year), there will be down time, maybe 4~8 hours per week.
Downtime - sysadmins' nightmare. This shall be a lesson for those who want to host servers at home.
