I didn't try ext2. All filesystems were on top of SoftRAID1 or
SoftRAID5. / was on md1(hda5/hdb5). Usually I do RAID over two channels
(md1(hda5/hdc5)) but for testing I didn't because of lack of UDMA
cables. I then found out that randomly different files were corrupt. For
example vi dumped core, after reboot vi went fine but rpm dumped core
and so on. Since UDMA uses CRC I thought it should be safe and I was
using 2 different UDMA controllers with the same effect. By now I'm sure
it has something to do with having two disks on one channel (corrupt DMA
transfers, errors in i820 chipset) because I made a new install on just
one disk and there was not one problem again. Unfortunately I don't have
the machines anymore to make more test.
If anybody is using i820 based motherboards and has two UDMA disks on
the same IDE channel, please try a SoftRAID1 install of RH-7.1-XFS and
test around with it.
