The size of the fs is the total size of the individual disks. When you limit the size, you limit the size of a disk, not the whole fs. IIRC, mkfs initializes the fs on the first disk, which is why it was using that size as the size of the whole fs, and then adds the other disks after ( which then add their size to the total fs size ). It might be nice if mkfs could take sizes for each disk, but it only seems to take one size for the initial disk. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJPMzf2AAoJEJrBOlT6nu75Ci8H/j3+8AR5H+UGOzpwMEBmPViJ PCVc5fAqOgLlQgjAII9dF74/1a6NyC9hjWBXPlhfrc3rA0JBj6x2AknvGnTQ6/Xo 4hMu8sFSSOtHf/aTXh7B7YJ/WrqDgkiEOSpcRVJyltzhKt0bbE3t9/IfxAhvkB1z 3CuEs9UeIn9wOV2fcyXoNMWpPQ+tNkxrvE817BHjPdQ5Z1+d2Cc0AxM22lgBVsZZ J+oneFOeqSIGZ9hbr0WVEjHaWJpxEapNmVGE5RIrpneTGpe3eAijqbBa8TEg+C2R iVCT7tBG3gOGhRoApMNM2IP2TgGLHMRgwP8QQv4/9MTNrOEP3G77tbCDHBfKMNA= =g+5L -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
