Power supply is sized large enough to support all the power consumption= of the=20 system. I was using 2.4.20 with Alan Cox's patches in order to add new IDE laye= r for=20 supporting this IDE controler. Maybe the problem comes from IDE layer in these kernels with -ac patche= s ? After high data trasnfers on the disks, file system corruption occurs. Last time, a php script reported this error : failed: Input/output erro= r (5). The server was rebooted and never started again as filesystems were too= much=20 corrupted. Today, I'm going to setup it again with 2.4.21-rc3 and I'm going to do = several=20 tests using Linux Test Project ( http://ltp.sourceforge.net/ ). What are the tests you would advise me in order to stress as much as po= ssible=20 the filesystems ?=20 I've noticed Cerberus could be a good test. But if anyone already met this problem, I would be happy to hear any ad= vice=20 ;-) Many thanks and best regards Eric - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
