Copying files to an AIX DVD is very slow, is there a way to increase the speed?
The DVD is formatted as a udfs filesystem. I have a lot of small compressed files that I want to store on several DVD's. It took over 11 hours to copy 7600 files. Is there a faster way to write these files to the DVD?
I used the following:
mount -Vudfs /dev/cd0 /mnt
find . -depth | cpio -pdum /mnt
The lscfg for the DVD is:
cd0 U789C.001.AAA0429-P2-D2 SATA DVD-RAM Drive
Manufacturer..............
Machine Type and Model......RMBO0020581
ROS Level and ID............RA33
Device Specific.(Z0)........05800
Part Number.................39J
EC Level....................H
FRU Number..................39
Hardware Location Code......U789C.001.AAA042
The system is:
System Model: IBM,8203-E4A
Processor Type: PowerPC_POWER6
Number Of Processors: 1
Processor Clock Speed: 4204 MHz
CPU Type: 64-bit
Kernel Type: 64-bit
LPAR Info: 1 10-BAF01
Memory Size: 3760 MB
Good Memory Size: 3760 MB
We are running AIX 5.3

wesly_chen,
Thank you for your reply. I was trying to keep the directory structure intact so that if they wanted to get a specific report from the DVD they would not have to search through different tar files.
It doesn't look like the DVD on AIX should be used for what I wanted to do.
Thanks again for your reply.

Thanks woolmilkporc, we are behind in the TL updates. Planning to upgrade to the latest TL12 in the next 2-3 weeks.
Hopefully that corrects the problem.
Thanks again,
