Now at four blocks since the initial transaction was attempted, no confirmations and can't find any record of the TX on the unconfirmed list @ bitcoincharts.com  - the client is absolutely up to date with the blockchain, so that is not the issue.

I have a bitcoind running for a private pool, and it has accumulated a fair number of blocks over the last six months (not many recently though).  It also has had quite a few payouts, so the wallet is "fragmented" (I think that's the proper term for it).

I decided to consolidate to a new wallet.dat because the one being used was becoming massive, and reloading bitcoind took a long time to parse the wallet.  So I created a new wallet and sent the old wallet balance to the new address.

So far it's been 30 minutes, and it hasn't shown up with 0/confirms on the new wallet, and it also isn't showing up on bitcoincharts.com's list of unconfirmed transactions.  Since I transferred the full balance, no fee was included by bitcoind, and I'm worried this transaction may never get passed along to nodes/confirmed.

Is there any way to know how large (size) the tx I tried to send was, and is there any way to revert it and include a transaction fee so that nodes won't ignore it?
