Da das ja derzeit groß in Mode ist habe ich mal 3 platten als raidz1 zusammengeknotet und mein FreeBSD 9-stable auf einem ZFS installiert. Ich habe soweit nichts zu meckern mit der Performance oder so, aber dieses Gerassel im 5 Sekundenabstand geht mir auf den Senkel...
Kann man den ARC etwas bremsen?
Steckt da einer in der Materie? Olli?
Gruß,
Holm
