I have a network server running FC5, with a hardware raid 3 card using 5 drives, as one large (1.2TB) partition in JFS. I chose JFS because of a recommendation for performance from a MythTV tutorial, but I don't really know much about file systems and am suspecting JFS to be causing my problems. I run samba, apache and MythTV on this machine, and there is essentially only one problem as far as I know. If I write to my server from the network (only tested from windows XP pc's using samba), I often get either an error in windows (Delayed Write Failed), or windows freezes while writing. On the server side, I generally get kernel messages from JFS that are completely meaningless to me, just a bunch of cryptic numbers and function calls. After one of these problems, I can't access the directory that was being written to, or my prompt freezes. Rebooting seems to be the only fix- jfs does some replaying and then the filesystem is perfect again. This sounds a lot like a cut and dry problem with JFS? except that MythTV does quite a lot of high intensity writing to the array and never has trouble like this, yet it happens frequently when being written to from samba. First of all, is there any known problem with using JFS with samba? Aside from that, I sort of figure maybe there is a samba configuration option that is to blame. Possibly something to do with buffering or with maximum throughput allowed? I am just guessing, but can anyone help? Thanks a lot! Will willconstable@gmail.com
