Hallo everybody, I have a Solaris 11 box here (Sun X4270) that crashes with a kernel panic during the import of a zpool (some 30TB) containing ~500 zfs filesystems after reboot. This causes a reboot loop, until booted single user and removed /etc/zfs/zpool.cache.

The server is a mirror for our primary file server and is synced via zfs send/receive. I saw a similar effect some time ago on a opensolaris box (build 111b). That time my final solution was to copy over the read only mounted stuff to a newly created pool. As it is the second time this failure occures (on different machines) I'm really concerned about overall reliability.... Any suggestions? thx Carsten _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
