Hi all,

I'm having some trouble with adding cache drives to a zpool, anyone got any ideas?

muslimwookie@Pyzee:~$ sudo zpool add aggr0 cache c25t10d1p2


cannot open '/dev/dsk/c25t10d1p2': I/O error


I have two SSDs in the system, I've created an 8gb partition on each drive for use as a mirrored write cache. I also have the remainder of the drive partitioned for use as the read only cache. However, when attempting to add it I get the error above.

Create one 100% Solaris partition and then use format to create two slices.
