Speaking of which, is there a way to read a FS configuration: how can I tell this FS really uses raid1 for both data and metadata? The used column is surprising: if it's a mirror why 111.01 and 111.03? And why all the space is being used anyway: I mean what's the difference between the 79.63GB and 111.0[13]? And the output of df is confusing too: /dev/sdb 234441648 83501968 150939680 36% /space It's reporting twice the total space but I think I remember looking it up and that should be fixed in a future kernel version. -- Mathieu Chouquet-Stringer mchouque@free.fr The sun itself sees not till heaven clears. -- William Shakespeare --
