I seem to have run into a small issue on my latest Windows Home Server install. I've got 350GB free on my server, but when I try to copy a 90GB chunk of data over I get an error saying "There is not enough space on Software. You need an additional 30GB to copy these files." or something to the same effect.
My setup is as follows:
- Processor - P4 2.4GHz
- Primary HDD - 80GB Seagate ST380011A automatically split into 20GB system drive (C:) and 60GB data drive (D:)
- Secondary HDD - 320GB Western Digital WD320JB
- No replication
So, after rebooting and trying again I Googled the problem (as most software developers would) and found a thread on MSDN called Error "There is not enough space on the disk" copying very large files. Apparently Drive Extender caches every bit of data that is transferred to the on the second partition of the primary and then pushes files to other physical hard drives. This means that - like in my case - if you try to transfer 90GB of data and the second partition is only 60GB, you will get this pretty lousy error message.
Now a choice needs to be made - live with the limitation and remember that I can only chunks of data as large as the partition at any one time, or format and start over again...
Seeing as I'm probably going to have to reinstall once WHS is in RTM (which should only be a couple of months away), I think I'm just going to have to learn to live with this and keep it in mind for then.
