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
