Hi all,
Recently i got myself a new machine (Dell R710) with 1 internal Dell
SAS/i and 2 sun hba (non-raid) .
From time to time this system just freezes and i noticed that it always
freezes after this message (shown in the /var/adm/messages) :

I was monitering the ssd cache using zpool iostat -v like you said. the

The benchmark even gave an insufficient space and terminated which proves
that it was

Hi Markus,
Thanks for your input and regarding the broadcom fw i already hitted
that issue and have downgraded it.
However for the Dell Bios i couldn't find anything older than 1.2.6. Do
you have by any chance the url for getting bios 1.1.4 like you say?

Hi David,
I think installgrub is unhappy that no s2 exists on c7t1d0.
I would detach c7t1d0s0 from the pool and follow these steps
to relabel/repartition this disk:

Hi,
I have tried what dedup does on a test dataset that I have filled with 372 GB
of partly redundant data. I have used snv_133. All in all, it was successful.
The net data volume was only 120 GB. Destruction of the dataset finally took a
while, but without any compromise of anything else.

Hi,
In your case, there are two other aspects:
- if you pool small devices as JBODS below a vdev
member, no superordinate parity will help you when
you loose a member of the underlying JBOD. The

good
part of your data.
