which is the smallest slice that is appropriate for creating a mirror (RAID 1) of /opt?
A disk drive fails in the production server and the database is down for three days while a new drive is installed and the database is recovered from tape. You must mirror the /opt file system without ordering any additional hardware. Given the size of the /opt file system:
# df -h
Filesystem size used avail capacity Mounted on
/dev/dsk/c0t0d0s5 5.1G 1.2G 3.9G 24% /opt
The following disk slices are available for use:
c0t0d0s4 5.18 GB
c1t0d0s1 1.24 GB
c1t0d0s2 8.43 GB
c1t0d0s4 1.19 GB
c1t0d0s6 6.00 GB
Without repartitioning any disks, which is the smallest slice that is appropriate for creating a mirror (RAID 1) of /opt?
