We wanted to upgrade our hosting server from FreeBSD 6.2, 3ware 8506-4LP SATA RAID, raid 5 to FreeBSD 7.1 (RC for now), 9550SXU-4LP, raid 10 We have tested the new installation on ASUS P5K WS motherboard with PCI-X slot while the server kept running. The server has Supermicro X5DPE-G2 (pretty old one, 2004). So, when everything was ready, i just took out the old controller and disks and installed the new controller and the array disks. The system booted up, but when i started very intense file operations the file system just froze. The weird thing is that any open program which does not use filesystem kept running fine. For example, i could type and edit in open ee editor, but copying progress bar in midnight commander just stood still. If i tried to save file or open file or do anything disk related from ee in another console the program froze too, apparently waiting for disk system to reply forever (i tried waiting for 20 minutes). I could even connect to ssh port, but it does not auth because sshd needs to read something from the disk. I put everything back into Asus P5K WS and tested it. Everything worked fine again. Any idea what might going on here? OS bugs aside, a dead disk that keeps getting IO request explains all symptoms. Dead can also mean, faulty cable, buggy connector. I would expect the hardware raid controller to pick up on it though and remove it from the array. No, not the case here. As i said, the same controller with the same disks work perfectly on ASUS motherboard. -- Artem ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
