It seemed to pass dbench runs OK, but then I started simultaneously running dbench and nbench on two different disks (I have a new test machine with more disks available). I am getting failures like this: Jan 23 06:54:38 dev4-003 kernel: journal_bmap: journal block not found at offset 1036 on sdc1 Jan 23 06:54:38 dev4-003 kernel: Aborting journal on device sdc1. Jan 23 13:19:43 dev4-003 kernel: journal_bmap: journal block not found at offset 1036 on sdd1 Jan 23 13:19:43 dev4-003 kernel: Aborting journal on device sdd1. Jan 23 13:19:43 dev4-003 kernel: EXT3-fs error (device sdd1) in start_transaction: Readonly filesystem The first failure was on the disk I am using for nbench (sdc). The second is during a later run on the disk I am using the dbench (sdd). I rebooted between the runs. It's interesting that its failing at exactly the same offset both times. Is there anything magic about offset 1036? The new test machine is a 4 way PIII, with 4G ram, and 4 36G SCSI disks. The test machine I have been using previously was a 2 way (+hyperthreaded) Xeon. I'll see if I can reproduce the problem with just dbench or just nbench. Cheers, Tridge
