Note that you can do similiar things via NFS mounts: 1-pong# showmount -e export list for pong: /Disks/d60 @12.38.161/25 /Disks/d70 @12.38.161/25 /export @12.38.161/25 2-pong# cd /export 3-pong# ls /export Backups@ Darwin@ Library@ Packages@ Solaris@ cvsroot@ temp@ CodeFab@ Java@ OPENSTEP@ Projects@ Win32@ home@ 4-pong# ls -l total 13 lrwxrwxrwx 1 root 20 Jan 2 2002 Backups -> ../Disks/d70/Backups/ lrwxrwxrwx 1 root 20 Jan 2 2002 CodeFab -> ../Disks/d70/CodeFab/ lrwxrwxrwx 1 root 19 Jan 2 2002 Darwin -> ../Disks/d70/Darwin/ lrwxrwxrwx 1 root 17 Jan 2 2002 Java -> ../Disks/d70/Java/ lrwxrwxrwx 1 root 20 Jan 2 2002 Library -> ../Disks/d70/Library/ lrwxrwxrwx 1 root 21 Jan 2 2002 OPENSTEP -> ../Disks/d70/OPENSTEP/ lrwxrwxrwx 1 root 21 Jan 2 2002 Packages -> ../Disks/d70/Packages/ lrwxrwxrwx 1 root 21 Jan 2 2002 Projects -> ../Disks/d70/Projects/ lrwxrwxrwx 1 root 18 Oct 7 17:25 Solaris -> /Disks/d70/Solaris/ lrwxrwxrwx 1 root 18 Jan 2 2002 Win32 -> ../Disks/d70/Win32/ lrwxrwxrwx 1 root 20 Jan 3 2002 cvsroot -> ../Disks/d70/cvsroot/ lrwxrwxrwx 1 root 17 Jan 2 2002 home -> ../Disks/d60/home/ lrwxrwxrwx 1 root 17 Jan 2 2002 temp -> ../Disks/d70/temp/ ...clients mount pong:/export/Solaris (or whatever), and the symlink will cause them to access the actual file location in /Disks/dXX, which are a set of DiskSuite RAID-1,0 metadevices, similar to vinum. This way, I can move large trees of stuff between filesystem locations in order to balance space of I/O utilization, only change the symlink, and not have to change any of the clients or take anything down. [ My users do as much I/O to their home directories as they do to everything else combined, pretty much. ] -Chuck To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
