Dear list I have three partition of the same size on different disks (ad0, ad1 and ad2). In disklabel they show up as e: 2097152 720896 4.2BSD 2048 16384 89 # (Cyl. 715*- 2795*) (f: ... for ad1 and ad2) In df they show up as: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/ad0s1e 1032142 2 949570 0% /data0 /dev/ad1s1f 1032142 2 949570 0% /data1 /dev/ad2s1f 1032142 2 949570 0% /data2 MY FIRST QUESTION IS: In the vinum configuration's sd length attribute am I to use the df 1K-block or the df Avail size? (e.g. sd length 1032142 drive ... or sd lenth 949570 drive ...). I am asking because Lucas writes in AbsoluteBSD df Avail, but I used accidently 1k-block. I don't want to keep on installing and configuring and later on run into trouble. I cross checked on Lehey's web page but did not find any information. MY SECOND QUESTION IS: vinum(8) stated: "org organization [stripesize ] [stipesize] For type raid5, it specifies the size of a group. A group is a portion of a plex which stores the parity bits all in the same subdisk. It must be a factor of the plex size (in other words, the result of dividing the plex size by the stripe size must be an integer), and it must be a multiple of a disk sector (512 bytes)." I understand this as stripesize has to devide sd length by ) AND 512k has to devide stripesize by 0 is that true? TIA zheyu
