The filesytem block size limitation is that the block size must be <=
page size. So, if you have a Linux box that supports 16k pages, then
you can use up to 16k filesystem blocks on that machine. IA64 boxes do
support 16k pages. Opteron machines don't.
Regarding cxfs, you probably need to talk to your cxfs support folks about that. :) -Eric Gabor Forgacs wrote: Hi All, Is there a chance that the current 4k block sizelimitation can be avoided by using 16k pagesize on the 64 bit linux? Will it work on a cxfs san ?regards,gabor |
