It comes from a historic aversion toward the old SDS (Disksuite Suite). You can use soft partitions on top of hardware RAID. Suppose your hardware RAID'd disk is visible to the OS as c1t0d0 and you have slices 6 (many gigabytes) and 7 (<100MB) available: # Create the metadatabases metadb -a -c 3 -f c1t0d0s7 # Create 30 soft partitions, 500 MB each i=1000; while [ $i -lt 1030 ] ; do metainit d$i -p c1t0d0s6 500m newfs /dev/md/rdsk/d$i i=`expr $i + 1` done -- Mike Gerdts http://mgerdts.blogspot.com/ ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] Several zonepaths on a single slice
Thanks, ZFS wouldn't appear to be an option here as we are only dealing with a pair of internal disks with no SAN-attached storage. Paul John Clingan wrote: That's where you want to use zfs datasets. Push a dataset to each zone and mount zone-local bits, data and logs to filesystems created from that dataset. You can specify a quota per filesystem.
