    ZFS pool suspended

    973537
      Hi,

      We have an issue with Solaris 11.0 (SRU10.5). It is installed on a super micro system, with DDR write cache, SSD read cache and SAS disks. Every now and then these boxes end up in a "ZFS pool suspended" state, the OS still responds. As a consequence we need to reboot the box. Not yet able to capture a core dump or to reproduce the conditions/error. Upgrade to 11.1 not possible, due to some other bugs. Call logged at Oracle support.

      Does someone recognise this type of problem? And maybe some workarounds?

      Thanks
      Arno

          This sounds like a very serious problem.

          Is it the root pool that suspends across all of the systems?

          I would check all the usual diagnostic data as described below.

          Let me know if any of this reveals a common thread.

          Thanks, Cindy

          1. Review general system log messages:

          # more /var/adm/messages

          2. Review FMA fault logs:

          # fmadm faulty

          3. Review accumulating FMA fault info:

          # fmdump

          4. Review accumulating FMA error log:

          # fmdump -eV | more

          5. Check disk errors:

          # iostat -en
          # iostat -En

            Thanks for your reply. We did all the suggestions you made in your reply. However, still stuck. We are trying to find a way to mimic the issues and cause the problem so we do a crash dump. So far no luck. Suggestions still welcome.

            Regards,

              is this on the root pool or another and what's the failmode set to of the relevant pool(s)?

              we had something similar on a non-root pool due to a dodgy fibre cable...
