mysql tmpdir

[ron ramos]

Hi All,

i am planning on allocating a separate volume for tmpdir on my
slave(and most probably master), the volume
will be setup as a software RAID 0.for write performance increase i
noticed i cant just simply change it during
runtime, is there a way to update without mysq restart?

also, since i will be usig RAID 0, if 1 disk fails my tmpdir will be
broken, is that gonna cause mysql to fail, and again
the need to restart mysql. thank you in advanced.

Regards
Ron
