26 | 07/20
|
---|
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 |
|
---|
31 | 06/29
|
---|
32 | - make sure software RAID devices are formatted IF user says they're to be
|
---|
33 | - drivelist is struct now, not char[][]
|
---|
34 |
|
---|
35 | 06/26
|
---|
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 |
|
---|
39 | 06/22
|
---|
40 | - be sure not to resize non-NTFS images when restoring
|
---|
41 | - set non-NTFS images' partition types properly
|
---|
42 |
|
---|
43 | 06/19
|
---|
44 | - shut down all LVMs and VGs before prepping
|
---|
45 |
|
---|
46 | 05/07
|
---|
47 | - usage of parted2fdisk instead of fdisk alone (ia32/ia64 compatibility)
|
---|
48 | BCO
|
---|
49 |
|
---|
50 | 03/31
|
---|
51 | - rewrote partitioning and formatting code to call fdisk once per disk
|
---|
52 |
|
---|
53 | 10/21/2003
|
---|
54 | - suspend/resume Newt gui before/after calling do_my_funky_lvm_stuff()
|
---|
55 |
|
---|
56 | 10/20
|
---|
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 |
|
---|
64 | 10/07
|
---|
65 | - use strstr(format, "raid") instead of strcmp(format,"raid") to determin
|
---|
66 | if partition is a RAID component
|
---|
67 |
|
---|
68 | 09/23
|
---|
69 | - better comments
|
---|
70 |
|
---|
71 | 09/18
|
---|
72 | - better logging of RAID activity
|
---|
73 |
|
---|
74 | 05/05
|
---|
75 | - added Joshua Oreman's FreeBSD patches
|
---|
76 |
|
---|
77 | 04/30
|
---|
78 | - added textonly mode
|
---|
79 |
|
---|
80 | 04/24
|
---|
81 | - added lots of assert()'s and log_OS_error()'s
|
---|
82 |
|
---|
83 | 04/21
|
---|
84 | - format_everything() --- don't let bar go too far
|
---|
85 | - mkfs -c to check for bad blocks when formatting
|
---|
86 |
|
---|
87 | 04/04
|
---|
88 | - misc clean-up (Tom Mortell)
|
---|
89 |
|
---|
90 | 01/15/2003
|
---|
91 | - added code for LVM and SW Raid (Brian Borgeson)
|
---|
92 |
|
---|
93 | 12/10/2002
|
---|
94 | - line 1238: friendlier output
|
---|
95 |
|
---|
96 | 11/20
|
---|
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 |
|
---|
102 | 09/09
|
---|
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 |
|
---|
106 | 07/01 - 07/31
|
---|
107 | - added hooks to libmondo
|
---|
108 | - RAID enhancements (Philippe de Muyter)
|
---|
109 |
|
---|
110 | 01/01 - 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 |
|
---|
145 | 11/22/2001
|
---|
146 | - preliminary code review
|
---|
147 | - created on Nov 22nd, 2001
