OpenZFS on OS X

Boot to safe mode, open /usr/libexec/zfs/launchd.d/zpool-import-all.sh, and change

Code: Select all

"${ZPOOL}" import -a
touch "${ZPOOL_IMPORT_ALL_COOKIE}"

to

Code: Select all

# "${ZPOOL}" import -a
# touch "${ZPOOL_IMPORT_ALL_COOKIE}"

Is there any automated mechanism to suppress auto-import following a kernel panic?

No, nor does that make much sense, since it is not trivial to determine whether a panic is attributable to ZFS, let alone a panic particular to import, which the vast majority of the time it is not. Moreover, this is one of the main reasons safe mode exists on OS X - to deal with third party kext issues.

Instead of "safe mode," I suppose I should have said "safe mode or equivalent."

The same changes can be made from safe mode, from a restore partition, from OS X installation media (I keep a partition with the complete OS X installer at the end of my system drive), or from another OS X installation. So indeed one need not "assume that safe mode will be possible in a troubleshooting situation" to deal with a third-party kext issue just as easily as you could from safe mode itself.
