FreeBSD sunslave 7.0-STABLE FreeBSD 7.0-STABLE #1: Thu May 8 19:23:18 UTC 2008 root@sunslave:/usr/obj/usr/src/sys/SLAVENODE sparc64
>Description:
I've two SUN E450 workstations both connected to 4 StorEDGE A1000.
The first machine has 4GB of RAM and 4 CPUs, the second (where the problem appears)
has 1.5GB of RAM and 3 CPUs.
On the first workstation I created a zpool (raidz named "store") with 32 disks.
All works fine, export / import works fine. I tried to export the
pool on the first workstation (works) and then to import the pool on the
second workstation (fails):
----------->8------------
sunslave# zpool import store
internal error: Value too large to be stored in data type
Abort (core dumped)
