copy CDROM to filesystem

[jaki]

Hi all,
while doing an SAP upgrade on an AIX 4.3.3 DB server its necessary to mount several CD's. There is the possibility to give multiple CD Mountpoints, to avoid the upgrade-procedure to stop because the nexe CD must be mouted, but my system only has 1 cdrom. The idea is to copy the several CD's to a filesystem (each in a seperate directory) and give these as CD mountpoints to SAP upgrade procedure.

The Problem:
On a CDFS you can access all files and Dirs in capital or in small letters ... when cpoied to a Filesystem on disk its only accessable in small letters (casesensitive) but the upgrade procedure tries to access File in Capial Letter Filenames and Paths ... any ideas to avoid this ? or is there a Filesystem which is not Case sensitive as CDFS for a Disk?

thanks in andvance ...
Mark

Hi,

What did you use to copy files ? It seems to me that if they are in small letters on CD, they should be in small letters on your filesystem (if you copy the hole CD with something like "cd /cdrom; tar cf - . | (cd to_dir; tar xf -)" )

Anyway, you can always rename everything with a simple loop like "cd your_dir; for i in `find .`; do mv $i `echo $i | tr [:lower:] [:upper:]`; done"

No, the filenames are in lowercase but the scripts are looking for uppercase names, which doesn't matter on a cdrom but won't work on JFS.

Hi Mark,
use tar instead cp and all will be copied well.
# cd /cdrom
# tar -cvf - *|(cd /NeededFS;tar -xvf -)

the files seem to be in lower cases on the CD, but can also be accesses in upper-cases:

if i use tar to copy the CD all files and dirs are also created in lowercases ...

 

[nwardez]

yes, so what about the loop on the files copied if you want to acces them as uppercase letters ?

 

[jaki]

yes ... this satisfies my request if the Program tries to access uppercase lettered Filenames ... I just thought if there are any other possibilities ...

There is a "-o nocase" option you can specify when mounting a filesystem. I've just play with it but it doesn't seem to be significant on JFS ...
