Greetings I'm facing serious problems with a Raid partition on UATA133 bus. The box is a dual athlon MP with asus MB and REDHAT 8.0. The entire system except /home stand on two IBM 80Gb disks (on uata 100 bus) in Raid 1 with ext3. The /home partition stand on 3 Maxtor 120Gb "diamondmax plus 9" uata133 in Raid 5 with ext3. The system ran fine with 2.4.18-18.8.0smp official redhat kernel and the 3 Maxtor disks attached to and external Adaptec controller based on highpoint hpt370 chipset (note, i used just the ide bus functionality, since Raid was software). When i switched to 2.4.19 vanilla kernel i started to have problems, first of all it seem that the system with vanilla kernels can't deactivate swap in logical volume, leaving just an "invalid argument" error when i use swapoff command, but the real problem is that i started to experience regular FileSystem corrupitons (just on /home) with lots of data lost in reconstructions and fsck. At first i thought about problems with ext3 and compatibility between RH 8.0 and vanilla kernels (i also wrote about this on ext3-users list) but don't seem the case. Now i've replaced the highpoint card with a Maxtor pci card ata133 based on promise chipset 20269. I also tested vanilla 2.4.20 with ext3 patches. Theres nothing to do, problems persist, not only during high i/o throughtput, but also when i start to store large data on partition. I fell back to 2.4.18-18.8.0smp I didn't install the promise patch since it seem to me that is already included in rh kernel) without succes, it seem that when the data on disks reach about 30% of capacity troubles and corruptions manifests. I also thinking about basic design errors, since i have 3 uata 133 disks attached to a single pci controller all with dma access activated, somebody can confirm that this could represent a bandwith problem? When i try to use badblock or other hardware diagnostics tools based on badblock command the system freezes and at reboot i need to run fsck manually (with new data corruption and loss). Things are becoming nasty, since i would like to use reliable IDE system for low profile File Servers at work. I would like to ask if there are know issues about linux kernel, new Large ide disks and uata 100/133 bus, since it seem to me that many other people are experiencing problems like this. Thanks in Advance for your help.
