[cfarm-users] overheating and dead HBA

[Luke Yasuda]

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.
