OK. Of course. Cool!

The system is 4.0-STABLE, which is more or less 4.0-RELEASE right
now.
dump fails at the point were it is trying to convert the block
device listed in fstab to a raw device, by inserting a 'r' after
the last '/' in the pathname. This part of dump wasn't changed
since the initial import :)
in sbin/dump/main.c:546:
char *
rawname(cp)
char *cp;
{
static char rawbuf[MAXPATHLEN];
char *dp = strrchr(cp, '/');
if (dp == NULL)
return (NULL);
*dp = '\0';
(void)strncpy(rawbuf, cp, MAXPATHLEN - 1);
rawbuf[MAXPATHLEN-1] = '\0';
*dp = '/';
(void)strncat(rawbuf, "/r", MAXPATHLEN - 1 -
strlen(rawbuf));
(void)strncat(rawbuf, dp + 1, MAXPATHLEN - 1 -
strlen(rawbuf));
return (rawbuf);
}
So, here what dump says:
trumpet:vinum# dump 0af /dev/null /cluster1
DUMP: Date of this level 0 dump: Wed Mar 22 02:10:20 2000
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/vinum/rcluster1 (/cluster1) to /dev/null
DUMP: Cannot open /dev/vinum/rcluster1
which is rather expected.
My fstab has the line:
/dev/vinum/cluster1 /cluster1 ufs rw 2 2
Since you've enlighted me with the fact that there are only
character devices in vinum nowadays, my suggestion is putting a
symlink rfilesys->filesys in /dev/vinum for each filesystem, or
creating device nodes named rfilesys as well. This would make
dump(8) happy anyway.
Also, the manual pages (both vinum(4) vinum(8)) seem to be a bit
off here, since they mention both raw devices,
/dev/rvinum/rfilesys and /dev/vinum/rfilesys, none of which I
have (I do have /dev/rvinum/filesys, but they were probably made
under 3.4, right? Can I remove them?).
Oh, by the way, I love vinum. Thanks for all the hard work!
Cheers,
Palle
