Hm, it seems I don't understand that. I tried now on different servers,=20 using stat -f /disks/db --format '%s %S' 4096 4096 That filesystems were all created with su=3D64k,swidth=3D(values 4-8=20 depending on RAID). So I retried specifying directly in the mount=20 options: sunit=3D128,swidth=3D512 and it still reports "4096" for %s - or is %s not the value I should=20 look for? Some of the filesystems even have allocsize=3D specified, still=20 always 4096 is given back. Where is my problem? And while I am at it: Why does "mount" not provide the su=3D/sw=3D options= =20 that we can use to create a filesystem? Would make life easier, as it's=20 much easier to read su=3D64k,sw=3D7 than sunit=3D128,swidth=3D896. When I defined su/sw on mkfs, is it enough, or would I always have to=20 specify sunit/swidth with every mount too? =2D-=20 mit freundlichen Gr=FCssen, Michael Monnerie, Ing.
