On the server is planed to store 'larger' from 1GB up to 60GB. what would be best settings when formatting with xfs? is it better to use '-b size=4096' or the '512'? should i manipulate the '-i size=' to 2048? or use the default? i also dont get it with the write-disk cache at all, its an linux softraid, is the best then to use 'nobarrier' and let the 'disk write cache on'? or is best solution on linux softraid 'disk write cache' on with xfs barrier on? also, should i tweak with sunit,swidth? and how do i calculate best setting? thanks for any tipps n hints marko -- zbfmail - Mittendrin statt nur Datei!
