No, I don't have time to deal with SuSE regarding failure, the company I am working for is growing so fast, need to add dozens of servers every month. After switch to XFS, I seldom get problems, even if I got problem, I can quickly reboot nfs server because it is using XFS. > > 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. Oh, you don't put much load on it.
