Thanks, for your reply. I at least *feel* better knowing that my questions doesn't fall into the "too dumb to deserve an answer" category. :)

Hi Drew,

 Please read the following:

http://www.vinumvm.org/vinum/how-to-debug.html


I have.

And follow the instructions exactly. And I mean exactly.


I thought I had, with the exception of the /var/log/vinum_history and /var/log/messages files due to the size. However I offered to provide them separately.

Also keep the following in mind, Greg will try to help but
note carefully the sentence on this webpage:

"Since I wrote it, FreeBSD has changed its I/O structure, breaking many
things in Vinum. At the time of writing, a new version, provisionally
called gvinum, is being written"


Yes, however I thought that vinum is still the way to go with 4-STABLE versions. Is this still true?

 I myself have had one serious crash on a vinum RAID volume as
a result of a SCSI cable problem that blew away the volume.  (2
drives were corrupted, instead of just one, making it impossible
for the volume manager to repair by itself)  I sent all the info
to Greg but ultimately he wasn't able to offer any suggestions
on recovering the array so I just wiped it and started over.

Note that Greg DID NOT recommend wiping the array. In fact he
didn't recommend anything. The lack of any recommendation
appears to be his way of telling you "your volume is screwed,
wipe it and start over" Like most UNIX commands, if Greg
has nothing to offer, he says nothing at all, he won't tell you he
has nothing to offer. So, the lack of a response to your
original post you can probably take as an answer, to be honest.


I can understand that about Greg. I'm sure he has so many emails to deal with each day that there's no point spending time on replies that don't offer any benefit. But what really blows me away is that my volumes work if they are deleted and re-created. This tells me my volume is not "screwed" because they work. I just don't understand why they don't survive reboots. These are the same volumes that I've had since version 4.1 and they've worked flawlessly -- well there was the time I tried to add a firewire drive to a concatenated volume but had the SCSI delay set too low in the kernel so the drive was not available when vinum started. However once I figured that out (with help from Hidetoshi Shimokawa, the driver author), everything worked fine again. However the upgrade from 4.9 to 4.10 royally screwed up the vinum volumes and they haven't been right since.

This did teach me a lesson that I kind of knew already but
didn't think too much about. That is, a software array is no substitute
for a hardware array. In other words, vinum is a great thing
if what your wanting to do is use a bunch of cheap disks and
cheap controller cards to either get a giant partition, or to
stripe them together and get faster access. But it's not so
good if the intent is to get some crash recovery.


Agreed. I have backups for crash recovery. With the exception of /usr, I used vinum so that I could have large drives on which to store backups, mp3s, mpegs, online copies of software, etc.

I don't use and have never used vinum for /etc, /, /usr, /var
or any other system partitions. I only use it for partitions
that I want to mount AFTER the system is booted. If I were in
your shoes I'd nuke your system and start all over again and
rethink how I had it laid out. I would use a single disk for
the system then take the rest of the disks and put them together
under vinum. Then I'd mount that on /ftp and I'd softlink
whatever thing is gopping up space under /usr, for example
/usr/local/www, to a directory under /ftp


You have a valid point and I will heed your advice when I finally wipe and upgrade to 5-STABLE. In the beginning, it seemed to be a good idea to use vinum to stripe my /usr for speed. Since this is just a home/hobby system, I probably never really needed the speed increase but I wanted to experiment.

Vinum isn't going to give you any crash recovery
for /usr so there is really no point in making /usr a vinum
volume. Beyond that I really don't understand why you
are putting /usr as a vinum volume, espically as you yourself
said "Fortunately this volume is up and running or I would
really be in a mess" I mean, your basically saying your
hitting yourself in the face and you feel fortunate you
haven't broken your nose yet.


You're right and my nose is still straight. :) See above as to "why" I striped /usr.

Anyway, one other thing I will bring up:  How exactly did
you update your system?  Did you nuke and repave it?  Or did
you follow the instructions here EXACTLY:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html


As I have since version 4.1.  My steps are:

make buildworld
make buildkernel
make installkernel
make installworld
mergemaster (accept replacement of all files I have not modified and merge my mods with new files)
reboot


I see 19.4.1 has two steps between "make installkernel" and "make installworld" that I did not follow. Do you suspect this is where my problem lies? I need to upgrade to the latest security level so I could try this.

If you didn't do one or the other of these things then nobody is going
to help you.

Ted


Thanks your your time and input!

Subject: One Last Plea For Vinum Assistance


I sent the message below a couple of times but did not receive any response. I assume that it's because either I have a really difficult problem or am asking something really stupid. :) But anyway, I want to install additional memory in this machine and am sure I will run across the same problems after shutting down. So if anyone has any suggestions on how I might solve this issue, I'd really appreciate the input.

Thanks,

--- Original Message ---
Since an upgrade from 4.9 to 4.10, I've had problems with
vinum.  The basic
problem is that upon reboot, two of my vinum drives show up as
"referenced" and
thus create the associated chaos.  I've tried many things and fiddled
around
quite a bit so I can't say exactly what I've done.  I can
include all of
the
entries in the history file since Oct. 31 if that's a help but
it would
be a
long list.

So prior to digging that deep, I will describe where I stand
currently and
where I want to finish.  Currently, I have one vinum volume
that I use for
/usr. Fortunately this volume is up and running or I would
really be in a
mess. Here's the 'vinum list' output in this state:

blacklamb# vinum
vinum -> list

S usr.p0.s1             State: up       PO:      256 kB Size:
    8383 MB

I want to add another volume and mount it on /ftp.  After creating the
volume,
vinum sees it and it appears OK as indicated in this output:

vinum -> list
5 drives:
D disk1                 State: up       Device /dev/da0s1h      Avail:

S ftp.p0.s2             State: up       PO:      149 GB Size:
     111 GB

Next I 'quit' the vinum command line and fsck my newly created
volume.  It
finishes successfully and I mount it:

blacklamb# df

I recheck with the 'vinum list' command and the output is the same as
above.
Now I cross my fingers and reboot to see if the volume comes
up properly on
startup.  However ftp3 (/dev/da3s1h) comes up 'referenced' and causes
problems.

Now I delete all references to the ftp volume by running these

Yet the 'reference to ftp3 remains.

Why does the list output show "1 drives:" when there are three listed
and two
working?  Anyway, I've been here before and I quit vinum.
Then I issue
these
commands:

Since everything appears correct, this seems like a good place
to do 'vinum
saveconfig'.  Next I edit /etc/fstab so only /ftp is not mounted and
reboot.
The system reboots fine and the 'vinum list' is as it is
immediately above.


Running in full production mode, I create the ftp volume again:

After running fsck, I can mount and access the volume.  The system
continues to
run fine until the next reboot where the same problems start all over
again.  I
also have the same problem with another volume I wish to run called
"backup".
How can I fix my vinum volumes so they survive reboots?

Thanks for your help and Happy Holidays!

Drew
