Subject:   How recover ZFS pool
Message-ID:  <20141105143423.GA2033@ns.pbox.org>

next in thread | raw e-mail | index | archive | help

Hi,


My computer reboot every time. It crash at boot when /etc/rc.d/zfs starting, and reboot , and reboot ...
I try, in Single User mode, every zpool command crash the kernel.
The pool is a raidz1 with 3 disk and 1 cache on SSD.

I think, the last pkg update is about X11. The first crash maybe a x11 drivers issue.

I try :
- upgrading 10.0-RELEASE-p11 to 10.0-RELEASE-p12
- without SSD disk.
- with another adapter
=> same result.

The system is on UFS, so I could boot without ZFS. How could I recover data ?

thanks for your help,

Luc.
