So those 250GB drives are closer to ~230GB drives. In raid 5 you loose capacity equal to 1 drive for the parity information, leaving 6 * ~230GB = ~1380GB. When you create a ffs file system, newfs leaves some space that only root can write to, this is typically 8% of the drive. In this case, that's about 110GB.Leaving ~1269GB available to the system. You can use tunefs to reduce the percentage of the drive that is reserved for root's use. Does this help clarify the situation? - -- Jeremy Faulkner -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFBh2r0fb0Lle2MIEIRArDMAJwJcDSEeTwUk5c99G/lTAvQp90UWQCeOR3m coQWDqeA6oGQSz8ZOnV5B5o= =COz3 -----END PGP SIGNATURE-----
