[OpenIndiana-discuss] ZFS problem hangs machine

[Bernd Helber]

Dear Michelle,

i assume you have physical access to the Box.

Are you able to boot the box?

Are you able to check if there are any Core Dumps left ond the Box?

Only to clarify, we're not talkin about a complete Zpool Corruption?
 ZFS hang the system completely, after zpool import on the reboot?


Regarding the message it looks to me that the disk is affected. Are you
able to give us a little bit more Informations regarding the issue?

With kind regards
