I've hit this bug on four of my Solaris 11 servers. Looking for anyone else who has seen it, as well as comments/speculation on cause.
This bug is pretty bad. If you are lucky you can import the pool read-only and migrate it elsewhere. I've also tried setting zfs:zfs_recover=1,aok=1 with varying results. http://docs.oracle.com/cd/E26502_01/html/E28978/gmkgj.html#scrolltoc Hardware platform: Supermicro X8DAH 144GB ram Supermicro sas2 jbods LSI 9200-8e controllers (Phase 13 fw) Zuesram log ZuesIops sas l2arc Seagate ST33000650SS sas drives All four servers are running the same hardware, so at first I suspected a problem there. I opened a ticket with Oracle which ended with this email: --------------------------------------------------------------------------------------------------------------------------------- We strongly expect that this is a software issue because this problem does not happen on Solaris 10. On Solaris 11, it happens with both the SPARC and the X64 versions of Solaris. We have quite a few customer who have seen this issue and we are in the process of working on a fix. Because we do not know the source of the problem yet, I cannot speculate on the time to fix. This particular portion of Solaris 11 (the virtual memory sub-system) is quite different than in Solaris 10. We re-wrote the memory management in order to get ready for systems with much more memory than Solaris 10 was designed to handle. Because this is the memory management system, there is not expected to be any work-around. Depending on your company's requirements, one possibility is to use Solaris 10 until this issue is resolved. I apologize for any inconvenience that this bug may cause. We are working on it as a Sev 1 Priority1 in sustaining engineering. --------------------------------------------------------------------------------------------------------------------------------- I am thinking about switching to an Illumos distro, but wondering if this problem may be present there as well. Thanks - Jamie
