Solaris 10 zone migration to Solaris 11 Express

[Ketan]

I was testing of migrating the solaris10 zone to solaris 11 express zone. I used cpio to create the archive with following syntax

#find db_zone -print | cpio -oP@ | gzip >/swdump/ovpidb_zone.cpio.gz

Then i created a solaris10 brand zone on the Solaris 11 environment and tried to attach the zone but i got following error.

It sounds like the zone was running when you created the archive. As a
result, the version of libc that is optimized for the SPARC64 CPU found
in the M5000 was mounted on top of /lib/libc.so.1. On the T-series box
that you are moving to, the CPU architecture is different and
incompatible with the type of optimization done for the SPARC64 CPU.

It looks like you were following the instructions at
http://download.oracle.com/docs/cd/E19963-01/html/821-1460/gentextid-12093.html#gcglo
but there "shut down the zone while creating the archive" step seems to
be missing.

Look for "unmount" on this page:

Hi
so this is a bug in the s11 docs, as it does need to mention the libc
bit of the step. I will log a bug.

Hi Steve,

I already checked this link .... and i did not see any hwcap libraries mounted on M-5K server ..

***@serverM5K # df -h | grep hw
***@serverM5K #

so could not unmount them .. though my T-5240 has those hwcap
libraries mounted


***@serverT5240#df -h | grep hw
/platform/SUNW,SPARC-Enterprise-T5240/lib/libc_psr/libc_psr_hwcap2.so.1 128G 4.2G 124G 4% /platform/sun4v/lib/libc_psr.so.1

***@serverT5240#


so had to put it on the forums to check with experts on the same

Can you provide the contents of the log file? You might find a line
starting with HWCAP:. Please provide this info.

After steve told me i checked the logs and found that lib files are missing from the zone which was being migrated (do not know the reason for it ).. and i just copied lib files from /lib to /zones/root/lib/ .. it went lil ahead but then it gave
me following error

so does this means we cannot migrate a sparse root zone to Solaris 11 express server ? or is it i 'm doing something wrong ?

Ahhh... it looks like you should have gotten the sparse zone error
message instead of the incompatible libc message. I've created:

7034572 zone install and attach from archive should do sparse check before libc check

That's the sparse zone error message I was expecting.

You can, but in order to do so, you need to be sure that the things that
are not included in a sparse zone get included in the archive. This
will cause the archive to be a lot larger and the zone will not be a
sparse root zone on Solaris 11.

To create the archive

zoneadm -z db_zone ready
cd $db_zone_zonepath/..
find db_zone -print | cpio -oP@ | gzip > /swdump/db_zone.cpio.gz
zoneadm -z db_zone halt

This is mentioned on page 377 of "System Administration Guilde: Oracle
Solaris Zones, Oracle Solaris 10 Containers, and Resource Management":

http://download.oracle.com/docs/cd/E19963-01/pdf/821-1460.pdf

It is also at:

http://download.oracle.com/docs/cd/E19963-01/html/821-1460/gjowt.html

However, this does not appear in the examples. I completely missed it
when I was reading the HTML version, but felt it stood out relatively
well in the PDF version.

Thanks .. i got it working .. zone is attached and booted .. i remember i read that sparse root zone is not supported anymore in Solaris 11 express.


But there is one more question/issue i 've been dealing with. Whenever we migrate a solaris 10u8 zone to a solaris10u8 zone it works fine but later on the live upgrade stucks or gives lots of issues on the target system complaining about the newly migrated zone .. is it very common issue or its just we are facing it. ?

Just to be clear, you migrated a NGZ from an s10_u8 system to another
s10_u8 system?
Not sure what you are exactly doing from above.

Do you have the Lu failure that you can copy and paste, along with the
zone details, ie the FS it's on etc, lufslist from the current BE and
the lucreate etc that was ran, plus what rev of 121430/121431 (
sparc/x86 ) Lu patch was installed.

[Ketan]

I do not have the logs rt now ..

We migrated a zone from one server to other .. on the same revision solaris 10 u8 the reason we migrate is to relieve the server of some load when it starts getting crunch on resources.
