Commit	Line	Data
805e021f CE	1	=over 4
	2
	3	=item [I<initcmd>]
	4
	5	Accommodates the command's use of the AFS command parser, and is optional.
	6
	7	=item B<-partition> <I<name of partition to salvage>>
	8
	9	Specifies the name of the partition to salvage. Specify the full partition
	10	name using the form F</vicepI<x>> or F</vicepI<xx>>. Omit this argument to
	11	salvage every partition on the file server machine.
	12
	13	=item B<-volumeid> <I<volume id to salvage>>
	14
	15	Specifies the volume ID of a specific read/write volume to salvage. The
	16	B<-partition> argument must be provided along with this one and specify
	17	the volume's actual site.
	18
	19	=item B<-debug>
	20
	21	Allows only one Salvager subprocess to run at a time, regardless of the
	22	setting of the B<-parallel> option. Include it when running the Salvager
	23	in a debugger to make the trace easier to interpret.
	24
	25	=item B<-nowrite>
	26
	27	Brings all undamaged volumes online without attempting to salvage any
	28	damaged volumes.
	29
	30	=item B<-inodes>
	31
	32	Records in the F</usr/afs/logs/SalvageLog> file a list of all AFS inodes
	33	that the Salvager modified.
	34
	35	=item B<-force>
	36
	37	Inspects all volumes for corruption, not just those that are marked as
	38	having been active when a crash occurred.
	39
	40	=item B<-oktozap>
	41
	42	Removes a volume that is so damaged that even issuing the B<vos zap>
	43	command with the B<-force> flag is ineffective. Combine it with the
	44	B<-partition> and B<-volumeid> arguments to identify the volume to remove.
	45	Using this flag will destroy data that cannot be read, so use only with
	46	caution and when you're certain that nothing in that volume is still
	47	needed.
	48
	49	=item B<-rootinodes>
	50
	51	Records in the F</usr/afs/logs/SalvageLog> file a list of all AFS inodes
	52	owned by the local superuser C<root>.
	53
	54	=item B<-salvagedirs>
	55
	56	Salvages entire directory structures, even if they do not appear to be
	57	damaged. By default, the Salvager salvages a directory only if it is
	58	flagged as corrupted.
	59
	60	=item B<-blockreads>
	61
	62	Forces the Salvager to read a partition one disk block (512 bytes) at a
	63	time and to skip any blocks that are too badly damaged to be salvaged.
	64	This allows it to salvage as many volumes as possible. By default, the
65	Salvager reads large disk blocks, which can cause it to exit prematurely
66	if it encounters disk errors. Use this flag if the partition to be
67	salvaged has disk errors.
68
69	=item B<-parallel> <I<# of max parallel partition salvaging>>
70
71	Specifies the maximum number of Salvager subprocesses to run in parallel.
72	Provide one of three values:
73
74	=over 4
75
76	=item *
77
78	An integer from the range C<1> to C<32>. A value of C<1> means that a
79	single Salvager process salvages the partitions sequentially.
80
81	=item *
82
83	The string C<all> to run up to four Salvager subprocesses in parallel on
84	partitions formatted as logical volumes that span multiple physical
85	disks. Use this value only with such logical volumes.
86
87	=item *
88
89	The string C<all> followed immediately (with no intervening space) by an
90	integer from the range C<1> to C<32>, to run the specified number of
91	Salvager subprocesses in parallel on partitions formatted as logical
92	volumes. Use this value only with such logical volumes.
93
94	=back
95
96	The BOS Server never starts more Salvager subprocesses than there are
97	partitions, and always starts only one process to salvage a single
98	volume. If this argument is omitted, up to four Salvager subprocesses run
99	in parallel but partitions on the same device are salvaged serially.
100
101	=item B<-tmpdir> <I<name of dir to place tmp files>>
102
103	Names a local disk directory in which the Salvager places the temporary
104	files it creates during a salvage operation, instead of writing them to
105	the partition being salvaged (the default). If the Salvager cannot write
106	to the specified directory, it attempts to write to the partition being
107	salvaged.
108
109	=item B<-showlog>
110
111	Displays on the standard output stream all log data that is being written
112	to the F</usr/afs/logs/SalvageLog> file.
113
114	=item B<-showsuid>
115
116	Displays a list of the pathnames for all files that have the setuid or
117	setgid mode bit set.
118
119	=item B<-showmounts>
120
121	Records in the F</usr/afs/logs/SalvageLog> file all mount points found in
122	each volume. The Salvager does not repair corruption in the volumes, if
123	any exists.
124
125	=item B<-orphans> (ignore \| remove \| attach)
126
127	Controls how the Salvager handles orphaned files and directories. Choose
128	one of the following three values:
129
130	=over 4
131
132	=item ignore
133
134	Leaves the orphaned objects on the disk, but prints a message to the
135	F</usr/afs/logs/SalvageLog> file reporting how many orphans were found and
136	the approximate number of kilobytes they are consuming. This is the
137	default if the B<-orphans> argument is omitted.
138
139	=item remove
140
141	Removes the orphaned objects, and prints a message to the
142	F</usr/afs/logs/SalvageLog> file reporting how many orphans were removed
143	and the approximate number of kilobytes they were consuming.
144
145	=item attach
146
147	Attaches the orphaned objects by creating a reference to them in the vnode
148	of the volume's root directory. Since each object's actual name is now
149	lost, the Salvager assigns each one a name of the following form:
150
151	=over 4
152
153	=item C<__ORPHANFILE__.I<index>> for files.
154
155	=item C<__ORPHANDIR__.I<index>> for directories.
156
157	=back
158
159	where I<index> is a two-digit number that uniquely identifies each
160	object. The orphans are charged against the volume's quota and appear in
161	the output of the B<ls> command issued against the volume's root
162	directory.
163
164	=back
165
166	=item B<-help>
167
168	Prints the online help for this command. All other valid options are
169	ignored.
170
171	=back
