I needed to add a second file system to one of my Solaris 10 zones this morning, and needed to do so without rebooting the zone. Since the global zone uses loopback mounts to present file systems to zones, adding a new file system was as easy as loopback mounting the file system into the zone’s file system:
mount -F lofs /filesystems/zone1oracle03 /zones/zone1/root/ora03
Once the file system was mounted, I added it to the zone configuration and then verified it was mounted:
mount | grep ora03
/filesystems/zone1oracle03 on filesystems/zone1oracle0 read/write/setuid/devices/nonbmand/exec/xattr/atime/dev=2d9000b on Sun Apr 12 10:43:19 2009 /zones/zone1/root/ora03 on /filesystems/zone1oracle03 read/write/setuid/devices/dev=2d9000b on Sun Apr 12 10:44:07 2009
Now to update my ASM disk group to use the storage.
