Recently we rebooted about 6 machines that had uptimes of 950+ days.
Last time fsck had run on the file systems was 2006.
When stuff gets that old, has been on-line and under heavy load all that
time you actually get paranoid about reboots. In my newly reaffirmed
opinion, at that stage reboots are at best a crap shoot. We lost several
hours to that gamble more than we had budgeted for. HP is getting more of
their gear back than in a usual month.
Maybe that is just life with HP.
