Hi ! I use ext3 over Software RAID-5, and access this through Samba/NFS/HTTP. From time to time, the machine hangs, no response to any kind of input (ping does not respond, nor keyboard/mouse). Only hard-reset does the trick. I also notices that 2 of the 7 disks are in UDMA 33, the others in UDMA 100. Does this have any impact ? (besides performance) If I do not mount the ext3 partition, it runs fine. Any help ? --Pascal My setup: RedHat 7.2, kernel 2.4.9-13, all updates with up2date raidtools-0.90-25 Software RAID-5: 7 x 76.8GB IDE, ext3 -> ~422GB nfs-utils-0.3.1-13.7.2.1 /: 4GB, ext3 /home: 67GB, ext3 Any other info needed?
