I'm also having this occur, it only seems to be one drive but I'm not 100% certain. It also seems to happen when I initiate a rebuild of one of the sub mirrors, however the tw_cli has nothing that appears to indicate that it's a problem. Not sure why but this drive shows up as "Not In Use" when I reboot my machine and seems to complete the rebuild, but it appears that I have to manually initiate the sub mirror rebuild from the controllers alt-3 boot menu. I can only assume that one of the drives is on it's way out since it appears to be isolated to an individual port on the controller. I had to use this 3ware card initially because I was unable to install Debian Sid on the machines on board sata controller for some reason, but that was about a year ago. I think the issue was resolved but since the 3ware raid set worked I simply left it in the system. This chirping is the only issue I've had until just today when all the sudden my machine started throwing I/O errors from the shell for every command... sysrq wouldn't even work and I had to hard cycle the power and everything came up fine, manually started a rebuild upon boot, and then noticed the rebuild pause then restart but finishing. Anyways hope this info helps...
Also ensuring that your able to dump your backups onto the array is not the best way to make sure it's working. Assuming you work out your hardware issue you should consider performing the entire process. IE: perform your backups, then do an actual restore as practice. But that's just my opinion....
Cheers
My Setup:
ASUS M5A78L-MLX
8G Coasiar Value Select
3ware 9500S
4 Seagate 400G SATA
