Hi All,
I have an interesting question that may or may not be answerable from
some internal
ZFS semantics.
I have a Sun Messaging Server which has 5 ZFS based email stores. The
Sun Messaging server
uses hard links to link identical messages together. Messages are stored
in standard SMTP

This is really standard Unix filesystem semantics.
I Understand this, just wanting

we have left. M$ also heavily discounts Exchange CALS to Edu and Oracle
is not very friendly
the way Sun was with their JES licensing. So it is bye bye Sun Messaging
Server for us.

Hello,
Does it make any sense to use a bunch of 15K SAS drives as L2ARC
cache for several TBs of SATA disks?
For example:
A STK2540 storage array with this configuration:
* Tray 1: Twelve (12) 146 GB @ 15K SAS HDDs.
* Tray 2: Twelve (12) 1 TB @ 7200 SATA HDDs.

I think the answer to this is no. UPS's do fail. If you have two

He told it's possible to grow a zpool by replacing every single disk
