11 Sorry for delayed response, I've been reading up
12 on gpt-fdisk [1].
13 Interesting reading on gpt-patch-fdisk....
14
15
16 So "parted" 2.3 in on the minimal cd I'm using:
17 install-amd64-minimal-20110714.iso
18 should be as sufficient as gparted?
19
20 If so, it looks like my disk(s) setups
21 which are identical are ok? [2] seems to
22 suggest that what I originally used (fdisk)
23 to partition a 4K block drive
24 (fdisk -H 224 -S 56 -l) will
25 work, but the drive is NOT optimized?
26
27 Using this (parted) syntax:
28
29
30 (parted) print
31 Model: ATA ST32000542AS (scsi)
32 Disk /dev/sda: 2000GB
33 Sector size (logical/physical): 512B/512B
34 Partition Table: msdos
35
36 Number Start End Size Type File system Flags
37 1 1049kB 269MB 268MB primary boot, raid
38 2 269MB 5414MB 5144MB primary raid
39 3 5414MB 2000GB 1995GB primary raid
40
41 and
42 (parted) align-check minimal 1
43 1 aligned
44 (parted) align-check optimal 1
45 1 aligned
46 (parted) align-check optimal 2
47 2 aligned
48 (parted) align-check optimal 3
49 3 aligned
50 (parted)
51
52
53 Should I conclude that sda and sdb are
54 correct and optimized for 4K block drives?
55
56 I never used parted before, so I can easily be making
57 a mistake [3] or poor assumption?
