[OpenIndiana-discuss] ZFS log/cache on a loopback device/file?

[Brett Dikeman]

Hi all,

We have an SSD with plenty of space on it, but when the OS was
installed, it was partitioned to use all of the disk. I'd like to use
some space on the SSD for a log or cache device for a 4-drive zpool.
Is that possible, for example by using a loopback device or file?  Or
is our only option exporting the ZFS filesystems on the SSD,
repartitioning, and replacing the filesystems?
