i'm new to xfs (courtesy of most helpful and encouraging commentary by stan hoeppner!) and i've seen some advice which says to make the block size -> 512 directory size -> 4096 on the other hand, i've also come across webpages which say don't mess around! keep the defaults as they are unless you are absolutely sure that changing it suits your purpose and know why. my question is for the data storage area on a web/email server. we're mainly going to have small files there and the email part will have only temporary files for the most part since people will download (ie pop). it makes sense to make the block size = 512, but i wonder if it really matters noticeably. the server is not a heavily visited one and only on very rare occasions will we get around 50000 hits/day - most of the time we're looking at under 10000 and that is with all the domains combined. -- in friendship, prad _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
