3 lfs mirror resync \- resynchronize an out-of-sync mirrored file
6 [\fB\-\-only\fR <\fImirror_id\fR[,...]>]
7 <\fImirrored_file\fR> [<\fImirrored_file2\fR>...]
9 This command resynchronizes out-of-sync mirrored file(s) specified by the path
10 name \fImirrored_file\fR.
12 If there is no stale mirror for the \fImirrored_file(s)\fR, then the command does
13 nothing. Otherwise, it will copy data from synced mirror to stale mirror(s), and
14 mark all successfully copied mirror(s) as SYNC.
16 If \fB\-\-only\fR option is not specified, the \fBnosync\fR mirror(s) (i.e.
17 components that have this flag set) will not be synced.
19 If \fB\-\-only\fR <\fImirror_id\fR[,...]> option is specified, then the
20 command will resynchronize the mirror(s) specified by the \fImirror_id\fR(s),
21 even nosync mirror(s) will be resynchronized as well.
22 This option cannot be used when multiple mirrored files are specified.
25 .BR \-\-only\fR\ <\fImirror_id\fR[,...]>
26 This option indicates which mirror(s) specified by \fImirror_id\fR(s) needs to
27 be resynchronized. The \fImirror_id\fR is the numerical unique identifier for
28 a mirror. Multiple \fImirror_id\fRs are separated by comma. This option cannot
29 be used when multiple mirrored files are specified.
32 .B lfs mirror resync /mnt/lustre/file1 /mnt/lustre/file2
33 Resynchronize all of the stale and sync-able mirror(s) for /mnt/lustre/file1 and /mnt/lustre/file2.
35 .B lfs mirror resync --only 4,5 /mnt/lustre/file1
36 Resynchronize mirrors with mirror ID 4 and 5 for /mnt/lustre/file1 even if they
37 are not marked as STALE.
39 The \fBlfs mirror resync\fR command is part of the Lustre filesystem.
