Short summary: Will a resize program for reiser4 be available within the next six months?
Long explanation: I use a 3ware SATA raid card for the main storage on my home network. I currently have 8 250 GB drives in a raid 5 + hot spare configuration. I chose this card because it allows for online capacity expansion. My plan was to wait until a few generations of hard drives emerged then upgrade them one at a time in cycles. This way my storage will periodically expand without any major downtime. When I first created the filesystem, there was a reiser4 resize program. This is no longer the case. I've began my next upgrade cycle with the purchase of two 750 GB drives. I plan to buy one each month until all eight are replaced. Now I need to make a decision. Do I backup my raid onto the new drives and reformat my raid with another filesystem (xfs, reiser3, jfs), or do I put these new drives into the array and assume that when the time comes to resize the filesystem that a working program will exist?
