Kernel panic and hard crash

Post by Hardcorefs » Mon Dec 10, 2012 7:55 am

Hi,
I built a very simple zpool file system.
During a copy of 100GB data the whole system crashed and required a hard reboot.

zio_notify_parent: zero io_children [0, 0], err 0

Code: Select all
zio_notify_parent: zero io_children [0, 0], err 0


That string appears on page one of a topic where a fix is discussed.
