I like them even better when stored as DVD5 or DVD9 iso images for playing them with VLC (VideoLan Client) on the wide-screen TV. But as my list of DVD's grew, my VxFS 3Tb filesystem started to become full (about 400 DVDs). With VxFS version 9 compression feature, I gained some time and was able to reclaim some space.. First of all: 1) Upgrade to SF6.0 2) Upgrade your DG (vxdg upgrade <dg>) 3) Upgrade your filesystem (vxupgrade -n 9 <fs>) Which gives: [root@thorbardin ~]# vxdg  upgrade local00dg [root@thorbardin ~]# vxupgrade -n 9 /export/home/raistlin/.private/movies0 UX:vxfs vxupgrade: ERROR: V-3-25236: /dev/vx/rdsk/local00dg/movies0_lv: already at disk layout version 9. [root@thorbardin ~]# find /export/home/raistlin/.private/movies0/DVD -name \*.iso|wc -l 512 So we have 512 DVD images on this FS. Let&

For those of you who don't want to watch Symantec's video, here's a quick & cheap howto of a VxFS de-dupe test using SFHA 6.0 under RHEL5.8: * First, here's our setup: [root@vcs11 ~]# df Filesystem           1K-blocks      Used Available Use% Mounted on /dev/mapper/rootdg-lv_root                       15109112   9258676   5070560  65% / /dev/sda1               101086     20027     75840  21% /boot tmpfs                  1029372         0   1029372   0% /dev/shm tmpfs                        4         0         4   0% /dev/vx /dev/vx/dsk/vcsdg/lv_vcs                         131072      4473    118813   4% /shared/vcs   * Let's check the initial state of this setup: [root@vcs11 ~]# /opt/VRTS/bin/fsadm -S shared /shared/vcs  Mountpoint    Size(KB)    Available(KB)   Used(KB)   Logical_Size(KB) Space_Saved(KB) /shared/vcs      131072        118813       4473             4473             0 * Enable de-dupe for our test filesystem: [root@vcs11 ~]# /opt/VRTS
