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.
15 If \fB\-\-only\fR <\fImirror_id\fR[,...]> option is specified, then the
16 command will resynchronize the mirror(s) specified by the \fImirror_id\fR(s).
17 This option cannot be used when multiple mirrored files are specified.
20 .BR \-\-only\fR\ <\fImirror_id\fR[,...]>
21 This option indicates which mirror(s) specified by \fImirror_id\fR(s) needs to
22 be resynchronized. The \fImirror_id\fR is the numerical unique identifier for
23 a mirror. Multiple \fImirror_id\fRs are separated by comma. This option cannot
24 be used when multiple mirrored files are specified.
27 .B lfs mirror resync /mnt/lustre/file1 /mnt/lustre/file2
28 Resynchronize all of the stale mirror(s) for /mnt/lustre/file1 and /mnt/lustre/file2.
30 .B lfs mirror resync --only 4,5 /mnt/lustre/file1
31 Resynchronize mirrors with mirror ID 4 and 5 for /mnt/lustre/file1 even if they
32 are not marked as STALE.
34 The \fBlfs mirror resync\fR command is part of the Lustre filesystem.
