And I still don't have a mental image of the connection between
this code, and actually telling the flippin drive to DO a %$#@
rewind!
However, this is what works here, 100%, like this:
[amanda@gene amanda-2.4.3b2-20020111]$ dd if=/dev/nst0 bs=32k
count=1 && amtape DailySet1 show && amcheck DailySet1

And I have uparrowed the prompt and repeated that 4 times.
And here is the modified tape_rdlabel() routine in tapeio.c:
char *
tape_rdlabel(devname, datestamp, label)
char *devname;
char **datestamp;
char **label;
{
int fd;
char *r = NULL;
if((fd = tape_open(devname, O_RDONLY)) < 0) {
r = errstr = newvstralloc(errstr,
"tape_rdlabel: tape open: ",
devname,
": ",
strerror(errno),
NULL);
} else if(fd >= 0)
tapefd_rewind(fd); /* a dummy rewind to make sure it is,
by G.eneHeskett. Doesn't always work. . . ): */
if(tapefd_rdlabel(fd, datestamp, label) != NULL) {
r = errstr;
}
if(fd >= 0) {
tapefd_rewind(fd); /* but this one does! */
tapefd_close(fd);
}
return r;
}
I'm sure I'll find out when amdump runs at 1am, if this is
actually workable. If it does, you _will_ hear me cheering from
there, wherever "there" is, at whatever local time I check. I'm
gmt -5:00 here in WV. :-)
