Failing journals are either I/O errors (dying hard disk drive) or otherwise Linux kernel bugs. I have not yet seen ext3fs + NFS (or only the journals) break under load (SUSE 9.2 and 10.0) for any other reason than a broken drive or broken cables. If you have a workload that reproduces the problem, report it to SUSE. OTOH, it's "only" one Xeon NFS server with 1 70 GB RAID5 and 1 292 GB RAID5 (MegaRAID SCSI 320-1 with BBU) with half a dozen users at any one time. > BTW, thank Craig Rodrigues, Alexander Kabaev, Russell Cattelan and all > others for porting XFS to FreeBSD, it's a good news for community.
