Extended Drive Size Information

Hello,

I have an extended drive for EmailXtender and all EMX-files are purged after archiving to an EMC Centera. The properties of the drive show 75% of space filled up; the DX extended drive report says the same. DX seems to be working fine, all files are purged (from my point of view), the files have the black icon and direct read is also activated. The meta-data is about 11MB of size. On this drive, there are only EMX-Files and the DX-Folder with its status information. I would have guessed the drive should be nearly empty?!

1) Where can I find the actual free/used disk size of the extended drive? Or does it mean I run into a problem if both (disk size and the DX report say the same)?
2) I would have thought to archive more information to the EMC Centera than the size of my extended drive? E.g. if the extended drive is 16GB and the EMX-files are each 90MB, shouldn't it be able to store more than 182 files, since the "DX-Shortcuts" are tiny?

Thanks for your help.
Regards, Jochen.

Strange. Each DX stub file consumes around 1500 bytes in the file system. Check for hidden files (like a page file). If I'm not mistaken, you can view the true amount of free space just by right clicking the drive in explorer.

One way to free up space is to create a purge rule and enable the option to purge during a background scan. Double check that background scans are enabled.

If that doesn't help try setting the DisableFileSizeFixup registry key to Yes under /hklm/sw/emc/dx/extended drives/xxx-xxxx
restart DX
This key normally causes DX to fixup file sizes for the benefit of windows explorer. For example, stubs will appear as 0kb after you set this key to Yes. This may help you better identify where all that space is being used.

Good luck.

I think that the OS cannot understand the operation of purging files so it is still gives the actual size after purging, i had the same thing on my server, it gives me a different size for each purged file which is the same as the actual size before purging, so i think it is a thing with the OS that it cannot understand the archiving.

the only thing now that is to wait and see if it will allow archiving on the extended drive if the OS giving that is full, then this will be difinitley clear.

best regards
Osama

You might also want to check how much space the MFT is taking up as well - a utility called NTFS Ifo from Sysinternals can give you this information.
