vdev_is_dead panic, NULL pointer of vd

[Bob via illumos-zfs]

Hi All,

We met a coredump with following call stacks, and actually the coredump
seems caused by a DISK, if we plugin the disk, and trigger a 'zpool import',
without any addtional args, the system just coredumped, nothing
displayed on console, but below dump info after reboot.
what happened in this case? Is it a bug or the on disk data corrupted by
mis-operations?

Thanks in advance.

It may be that there is something wrong with the data on disk. Can you
make a crash dump available? (contact me off-list if you'd prefer)

Hi All,
We met a coredump with following call stacks, and actually the coredump
seems caused by a DISK, if we plugin the disk, and trigger a 'zpool import',
without any addtional args, the system just coredumped, nothing displayed
on console, but below dump info after reboot.
what happened in this case? Is it a bug or the on disk data corrupted by
mis-operations?
Thanks in advance.

Given that he is in the middle of spa_load(), I don't imagine any ZFS
vnodes/inodes have been instantiated yet.

Hi All,
We met a coredump with following call stacks, and actually the coredump
seems caused by a DISK, if we plugin the disk, and trigger a 'zpool import',
without any addtional args, the system just coredumped, nothing
displayed on console, but below dump info after reboot.
what happened in this case? Is it a bug or the on disk data corrupted by
mis-operations?
Thanks in advance.

Oh, yeah, I was thinking of another similarly named function. Never mind :)

Post by Matthew Ahrens via illumos-zfs
Given that he is in the middle of spa_load(), I don't imagine any ZFS
vnodes/inodes have been instantiated yet.

Post by Gordon Ross via illumos-zfs
I think I've seen this one. Do you see a ZFS vnode with its mode bits
having zero for the inode type bits?

It may be that there is something wrong with the data on disk. Can you
make a crash dump available? (contact me off-list if you'd prefer)

Hi All,
We met a coredump with following call stacks, and actually the coredump
seems caused by a DISK, if we plugin the disk, and trigger a 'zpool import',
without any addtional args, the system just coredumped, nothing
displayed on console, but below dump info after reboot.
what happened in this case? Is it a bug or the on disk data corrupted
by mis-operations?
Thanks in advance.

The problem is that there are at least 3 devices in the pool, but the pool
config that was passed in from userland has only one device.

Does that match with your understanding of the pool layout, that it should
have at least 3 top-level VDEVs? Are they all still present on the system?
I'm not sure exactly how userland generates this config. Could you also
send the output of "zdb -l /dev/dsk/..." for each of the devices that
should be part of the pool?

Hi All,
We met a coredump with following call stacks, and actually the coredump
seems caused by a DISK, if we plugin the disk, and trigger a 'zpool import',
without any addtional args, the system just coredumped, nothing displayed

what happened in this case? Is it a bug or the on disk data corrupted by
mis-operations?
Thanks in advance.
