I'm using a Promise PDC20277 IDE controler (with pseudo RAID functions but I'm not using them). 4 Western Digital 120 GB with 8MB of cache are connected (Master/slave with good cables) to it. Power supply is sized large enough to support all the power consumption of the system. I was using 2.4.20 with Alan Cox's patches in order to add new IDE layer for supporting this IDE controler. Maybe the problem comes from IDE layer in these kernels with -ac patches ? After high data trasnfers on the disks, file system corruption occurs. Last time, a php script reported this error : failed: Input/output error (5). The server was rebooted and never started again as filesystems were too much corrupted. Today, I'm going to setup it again with 2.4.21-rc3 and I'm going to do several tests using Linux Test Project ( http://ltp.sourceforge.net/ ). What are the tests you would advise me in order to stress as much as possible the filesystems ? I've noticed Cerberus could be a good test. But if anyone already met this problem, I would be happy to hear any advice ;-) Many thanks and best regards Eric - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
