Re: [zfs-discuss] Which is better for root ZFS: mlc or slc SSD?

2008-09-26 Thread Adam Leventhal
For a root device it doesn't matter that much. You're not going to be writing to the device at a high data rate so write/erase cycles don't factor much (MLC can sustain about a factor of 10 more). With MLC you'll get 2-4x the capacity for the same price, but again that doesn't matter much

I am running OpenSolaris 2008.05 as a PV guest under Xen. If you import the bootable root pool of a VM into another Solaris VM, the root pool is no longer bootable. It is related to the device associated to the pool, which is originally c4d0s0, but on import (-f) becomes c0d2s0 in this case.
