zfs create -V 3G rpool/cache

I like the idea of swapping on SSD too, but why not make a zvol for the L2ARC
so your not limited by the hard partitioning?

GB/sec aggregate throughput. However, the 3124 is a PCI-X chip and hence is
used behind an Intel PCI serial-to-parallel bridge for PCIe applications: th

Try to detach one of the failed devices:

OK, I just did some checking, and my rpool was already set up with
autoreplace=off. It's necessary to use the -r bo

Thanks to everyone who made suggestions! This machine has run
memtest for a week and VTS for several days with no errors. It

Thanks for a reply.

It's now March 28.

There had been a discussion of the topic on this list bout a onth ago,
and I'd been told that similar ideas (compressed metadata/data in
ARC/L2ARC) is on zfs dev agenda.
