This is my first ZFS pool. I'm using an X4500 with 48 TB drives. Solaris is
5/09.
After the create zfs list shows 40.8T but after creating 4
filesystems/mountpoints the available drops 8.8TB to 32.1TB. What happened to
the 8.8TB. Is this much overhead normal?
zpool create -f zpool1 raidz c1t0d0 c2t0d0 c3t0d0 c5t0d0 c6t0d0 \
raidz c1t1d0 c2t1d0 c3t1d0 c4t1d0 c5t1d0 \
raidz c6t1d0 c1t2d0 c2t2d0 c3t2d0 c4t2d0 \
raidz c5t2d0 c6t2d0 c1t3d0 c2t3d0 c3t3d0 \
raidz c4t3d0 c5t3d0 c6t3d0 c1t4d0 c2t4d0 \
raidz c3t4d0 c5t4d0 c6t4d0 c1t5d0 c2t5d0 \
raidz c3t5d0 c4t5d0 c5t5d0 c6t5d0 c1t6d0 \
raidz c2t6d0 c3t6d0 c4t6d0 c5t6d0 c6t6d0 \
raidz c1t7d0 c2t7d0 c3t7d0 c4t7d0 c5t7d0 \

(PS. As I said this is my first time working with ZFS, if this is a dumb
question - just say so.)
