Yes, but where do you buy SuperMicro toys?

I’d like to report the ZFS related crash/bug described below. How do I go about
reporting the crash and what additional information is needed?
I’m using my own very simple test app that creates numerous directories and
files of randomly generated data. I have run the test app on two machines, bo

Currently there isn't a way to do this without having some
additional buffer disk space available.

Sorry, but looking again at the RMP page, I see that the chassis I
recommended is actually different than the one we have. I can't find
this chassis only online, but here's what we bought:

I suspect it's probably not a good idea but I was wondering if someone
could clarify the details.
I have 4 250G SATA(150) disks and 1 250G PATA(133) disk. Would it
cause problems if I created a raidz1 pool across all 5 drives?
I know the PATA drive is slower so would it slow the access across th
Is there a way to convert a 2 disk raid-z file system to a mirror without
backing up the data and restoring?
We have this:

Just checking status on the resilver/scrub + snap reset issue-- it is very
painful for large pools such as exist on thumpers that make heavy use of
snaps. Is this still on track for u5/pre-u5 or has it changed? Is there a
different view of these bugs with more information so I do no need to

I have a huge problem with space maps on thumper. Space maps takes over 3GB
and write operations generates massive read operations.
Before every spa sync phase zfs reads space maps from disk.
I decided to turn on compression for pool ( only for pool, not filesystems )
and it helps.

Back in April, I pinged this list[1] for help in specifying a ZFS server
that would handle high-capacity reads and writes. That server was
finally built and delivered, and I've blogged the results[2] as part of
a larger series[3] about that server.
