Solaris 10 SVM fails to boot from mirrored disk on 2 disk system; need help!

Post by Roger P. Johnso » Wed, 18 May 2005 08:36:04



Trying to make a Solaris 10 router out of Netra AC200 T1.

In a nutshell:
Solaris 10 3/05 Reduced Networking Software Group installed
Right out of the box. No patch clusters yet applied.
Installed the SVM missing pkg SUNWmdu not part of the Group install.
Got the boot disk mirrored/attached/sync'd up. All ok.

To test the the failover I shutdown the system, pull disk number 2 out
and power up.

On boot, the kernel loads, and then I get:

WARNING: md: d102 (Unavailable)
          Error writing ufs log state
          ufs log for / changed state to error
          Please unmount(1M) and run fsck (1M)

panic[cpu0]/thread=180e000: could not install the isa driver
....
syncing files systems ...done

I googled on the "ufs log" error but all I could find where references
to Disksuite for Solaris 7/8, maybe 9 and possibly a patch for it.
Nothing about Solaris 10.

What really irks me is that I practiced SVM for Solaris 10 on an extra
E450 where I could give a rats ass whether it worked or not (of course
it all worked and no problems, recoveries and all!). Now that it is for
real,I get problems. Been pissing away 7+ days on this beast and I need
help!

The AC200 has the latest OBP prom (4.0.17 IIRC) and the latest lom lite
firmware in it.

inetd and svcs looks ok to me. All enabled and not any problems.
I cannot give listsings as it is a work and isolated to a Wyse 60 for a
console.

Quick searching on sunsolve didn't reveal anything specific.
Anyone have some experience on this?

Thanks.
-Roger

This might be related:

Bug ID 6215065.

One of the SVM people suggested disabling ufs logging (remove 'logging'
from /etc/vfstab) for only the / filesystem, if my recollection is correct.

I don't think there's a patch for it yet to fully fix that problem.

I ran into the same thing during my Sol10/x86 SVM testing, too. ;)

I then found comments by Jerry Jelinek about that bug and I can tell you
his suggested workaround did indeed avoid this panic.

I stumbled upon that "solution" also, but forgot all about it when
writing the post. UFS logging is on by default on in Solaris 10. I did a
"nologging" in vfstab and got the same thing. But know I see I had the
wrong syntax for that test. Ugh.

I'll try a cluster patch. I see the topic was during the timeframe of
March 2005. That's about the release time for the Solaris 3/05 version....

This must be it (Jerry Jelinek):

Thanks for the tips Dan.
 
 
 

1. SVM boot disk mirroring on Solaris 9 x86

Hello,

We are using Solaris Volume Manager on Solaris 9 SPARC servers to mirror
the boot disk (RAID 1) so in case of one disk crashes we can still boot
on the other and have our system up. Now I wanted to ask if this is also
possible on x86 ?

We are currently planning on installing x86 Solaris 9 servers and would
also like to mirror the boot disk using SVM. Is this also possible ? If
yes is it the same procedure as with SPARC ?

I am not so sure about installing the boot block on the second disk on
x86...

Many thanks

3. Solaris 10, built new disk, now cannot boot off solaris 8 disk???

4. Announce: Tk based alarm clock

5. Is it possible to mirror disks without physically removing disk the incompletely mirrored disk

6. pppd and routeing

7. Solaris 10, Mirroring, pre-existing disk

8. Driver Loading FPGA Device

9. testing Disk Mirroring with SVM

10. Solaris 10 installation fails with "no disk found".

11. How-to mirror system disk using disk suite

12. Software RAID 1 - disks mirror but the secondary disk does not boot.

13. Is a hot spare disk needed for disk mirroring?
