[zones-discuss] Solaris 10 zone migration to Solaris 11 Express
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. *** zoneadm -z s10zone1 attach -a /home/vneb/ovpidb_zone.cpio.gz Log File: /var/tmp/s10zone1.attach_log.oFaavh Attaching... ERROR: The image was created with an incompatible libc.so.1 hwcap lofs mount. The zone will not boot on this platform. See the zone's documentation for the recommended way to create the archive.

I 'm moving solaris 10u8 zone from M5000 to a Ldom2.0 Solaris11 express 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. -- Mike Gerdts Solaris Core OS / Zones ___ zones-discuss mailing list zones-discuss@opensolaris.org

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 .. root@serverM5K # df -h | grep hw root@serverM5K # so could not unmount them .. though my T-5240 has those hwcap libraries mounted root@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 /platform/SUNW,SPARC-Enterprise-T5240/lib/sparcv9/libc_psr/libc_psr_hwcap2.so.1 128G 4.2G 124G 4%/platform/sun4v/lib/sparcv9/libc_psr.so.1 root@serverT5240# so had to put it on the forums to check with experts on the same - Show quoted text - -- This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org

Ahhh... it looks like you should have gotten the sparse zone error message instead of the incompatible libc message.

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.
