Odd rm behavior on 5.4-S with 3ware raid

[Brandon Fosdick]

The machine is an amd64 running 5.4-S with a 3ware 9500S-12 card.

I wrote a test script to fill up the raid array with lots of files, and it did just that. Afterwards I did a 'rm *' to clean out the test files and naturally checked the results with ls. All the files were gone. For some reason, after waiting a few seconds, I did ls again. Some of the files had magically reappeared. After a few more seconds, more files were back. Its still happening as I type this. The drive lights are flashing wildly, but I kind of expected that. df is also showing that the array is filling back up.

Any ideas? Is my computer possessed?
