27- when starting RAID, don't do it twice :)
28- moved Joshua's new get_phys_size_of_drive() code
29 from resize_drive... into get_phys_size_of_drive()
30
3106/29
32- make sure software RAID devices are formatted IF user says they're to be
33- drivelist is struct now, not char[][]
34
3506/26
36- drop make_relevant_partition_bootable(); do it yourself in C (mostly)
37- offer to reboot if partition table is locked up by the kernel
38
3906/22
40- be sure not to resize non-NTFS images when restoring
41- set non-NTFS images' partition types properly
42
4306/19
44- shut down all LVMs and VGs before prepping
45
4605/07
47- usage of parted2fdisk instead of fdisk alone (ia32/ia64 compatibility)
48 BCO
49
5003/31
51- rewrote partitioning and formatting code to call fdisk once per disk
52
5310/21/2003
54- suspend/resume Newt gui before/after calling do_my_funky_lvm_stuff()
55
5610/20
57- rewrote format_everything() - what a mess it was.
58 It now does things in three phases:-
59 - formats software RAID devices (/dev/md0, etc.)
60 - formats and configures LVM devices
61 - formats regular partitions (/dev/hda1, /dev/sdb2, etc.)
62 and any LVMs recently prepped
63
6410/07
65- use strstr(format, "raid") instead of strcmp(format,"raid") to determin
66 if partition is a RAID component
67
6809/23
69- better comments
70
7109/18
72- better logging of RAID activity
73
7405/05
75- added Joshua Oreman's FreeBSD patches
76
7704/30
78- added textonly mode
79
8004/24
81- added lots of assert()'s and log_OS_error()'s
82
8304/21
84- format_everything() --- don't let bar go too far
85- mkfs -c to check for bad blocks when formatting
86
8704/04
88- misc clean-up (Tom Mortell)
89
9001/15/2003
91- added code for LVM and SW Raid (Brian Borgeson)
92
9312/10/2002
94- line 1238: friendlier output
95
9611/20
97- when wiping a given device in preparation for partitioning + formatting
98 it, don't wipe the MBR; just the partition table. That allows for
99 stupid-ass Compaq users who like to play with their MBR's.
100- disable mountlist.txt-->mountlist.txt.pre-resize copying (superfluous)
101
10209/09
103- run_program_and_log_output() now takes boolean operator to specify
104 whether it will log its activities in the event of _success_
105
10607/01 - 07/31
107- added hooks to libmondo
108- RAID enhancements (Philippe de Muyter)
109
11001/01 - 03/31
111- partition_device() will refuse to partition /dev/mdX now (cos it's a
112 virtual drive); however, it will return 0 (i.e. not an error)
113- make_list_of_drives() will exclude /dev/md* from list
114- mkreiserfs -ff instead of -q (Andy Glass)
115- don't resize drive if drive not found (or if its size cannot be det'd)
116- when generating list of drives from mountlist, skip the 'p' at the end
117 of drive name if /dev/ida/ or /dev/cciss/; just do it (Michael Eisenberg)
118- don't specify journal size when formatting ext3
119 (used to have -Jsize=10 in the call to mkfs)
120- handles files >2GB in size
121- format interactively, if Interactive Mode
122- removed reference to g_tape_size
123- when executing /tmp/i-want-my-lvm, only record the error# if the command
124 was _not_ an 'insmod' command
125- pass partition size to fdisk in Kilobytes now, not Megabytes
126- log fdisk's output to /tmp/mondo-restore.log if it fails
127- don't try to format partitions of type 'image'
128- don't type to set types of 'image' partitions
129- if format code is 1 or 2 chars then assume it is a hex string
130- took out all '/ /' comments
131- don't extrapolate/add partition from RAID dev to mountlist if it's already
132 present in mountlist
133- less repetitive logging in the event of vacuum-packing of last part'n
134- no extrapolation at all: RAID partitions should be listed in mountlist
135 already, thanks to either Mindi v0.5x or the mountlist editor itself
136- no longer say, 'and logging to...' when setting a partition's type
137- don't run mkfs on RAID partitions (/dev/hd*, /dev/sd*); just set type
138- the setting of a partition's type now takes place in a separate subroutine
139 from the subroutine that actually creates the partition
140- no need to set type if 83: 83 is the default (under fdisk)
141- turned on '-Wall'; cleaned up some cruft
142- if vacuum-packing partition (i.e. size=0MB --> max) then say, "(maximum)"
143 not, "(0 MB)"
144
14511/22/2001
146- preliminary code review
147- created on Nov 22nd, 2001
