Hi -- hope this is the right place to report this issue:
Suddenly today my macbook crashed with a kernel panic, and it would not come back but crash after each reboot.
I tracked it down to crashing in zpool during the startup sequence. So I disabled the org.openzfsonosx.zpool-import-all.plist and the laptop runs again.
On my macbook I'm running the official 1.4.5 release, and have (amongst others) my home directory mounted as a zfs file system.
Running zpool -a by hand immediately crashed the machine again, reproducibly. I connected an external backup of this pool (which however is a couple of days old), and could zpool import that one without problems.
So, something is "broken" in that pool, making zpool import panic the kernel.
The traceback shows
panic(cpu 0 caller 0xffffff7f95920681): "VERIFY3(" "0" " " "==" " " "zap_remove_int(zfsvfs->z_os, zfsvfs->z_unlinkedobj, zp->z_id, tx)" ") " "failed (" "0" " " "==" " " "2" ")\n"@zfs_dir.c:763
Any help how to get this zpool back would be welcome. If tracebacks or debug info is needed I can provide that.
Thanks a lot and best regards, LatB
