Victor,
I've reproduced the crash and have vmdump.0 and dump device files. How do I
query the stack on crash for your analysis? What other analysis should I
provide?
Thanks

There are a significant number of variables to work through with dedup and

features for now so your not working with too many elements.

Does it have the hardware functionality to detect the power outage and do force

Any more detailed info about the capacity (farad) of this supercap and how long
one discharge will be?
Thanks.

A supercap on a SSD drive only needs to sustain the data until it has
been saved (perhaps 10 milliseconds). It is different than a RAID
array battery.

Thanks to everyone for such helpful and detailed answers. Contrary to some of
the trolls in other threads, I've had a fantastic experience here, and am
grateful to the community.
Based on the feedback, I'll upgrade my machine to 8 GB of RAM. I only have two

I tried that - it didn't work - I replaced the drive with a new one, that
worked, and then I made a new zpool on the old drive with zfs-fuse in L

Hey Mitch,
The zpool split feature is available in the OpenSolaris release if
you upgrade to build 131.
You can read about the requirements here:

See the ZFS Admin Guide, page 89-90

Well, I was doing a ZFS send / receive to backup a large (60 GB) of

had to reboot the system, after which it appeared to come up clean. As
soon as I tried the backup again I noticed the pool reported the error

Interesting, this time it worked! Does specifying the device to clear
cause the command to behave differently? I had assumed w/out the device
specification, the clear would just apply to all devices in the pool
(which are just the one).
