Would the system be able to halt if something was unplugged/some

That way if something got tripped, I could fix it before any
corruption or issue occured.
That would be my safety net, I suppose.

Dear list,
Solaris 10 U3 on SPARC.
I had a 197GB raidz storage pool. Within that pool, I had allocated a
191GB zvol (filesystem A), and a 6.75GB zvol (filesystem B). These used
all but a couple hundred K of the zpool. Both zvols contained UFS
filesystems with logging enabled. The (A) filesyst

The big problem is that if you don't do your redundancy in the zpool, then the
loss of a single device flatlines the system. This occurs in single device
