zfs discuss - May 2011 - ZFS issues and the choice of platform

Hi all

I have a few servers running openindiana 148, and it''s been running
rather well for some time. Lately, however, we''ve seen some hichups
that may be related to the platform, rather than the hardware. The actual errors
have been variable. Some issues were due to some supermicro backplanes that
tended to fail, causing drives to report massive i/o errors. But then, the
really bad ones are issues where zfs reports bad drives even though iostat
report them as good. So far, we haven''t lost a pool, it has been sorted
out, but I still wonder what happens if I''m gone for a few weeks and
something like that happens.

The systems where we have had issues, are two 100TB boxes, with some 160TB
"raw" storage each, so licensing this with nexentastor will be rather
expensive. What would you suggest? Will a solaris express install give us good
support when the shit hits the fan?

No more so than what you have now, without a support contract.

Are you suggesting that support contracts on sol11exp are useless?  Maybe I
should go tell my boss to cancel ours...  *sic*

Any support contract is worth some things
In your case you will need
1. Server contract 
2. Array contract or part of server
3. Solaris/solaris express support

There is no free lunch, if you want support you will need to pay $ or your xxx
is on the line

No, not at all.  The OP didn''t mention having or intending to buy one,
and talked only about an "install" of SX, vs paid support for nexenta.
I was just pointing out the gap, in case wrong assumptions were being
made.
