I have a reproducable problem with corrupted data read from a RAID1-array. Setup: HW: 2 S-ATA-Disks (160GB each) -> /dev/md4 RAID1 Promise S150 TX4 - Controller AMD Sempron 2200+ SW: Fedora Core 3 Kernel 2.6.10 unpatched Samba (for read/write-accesses) SW-Raid Everything works fine with only one drive in the array. If the second is synced up read accesses return corrupted data. Interesting: If you remove again the second disk. The same files will be read correctly again (no matter if written while only one disk is in the array or two are synced!)! Tests with differend disks (2x80GB Seagate and 2x160GB Samsung), different partition sizes (20, 40, 80, 160GB), different filesytems (ext3, ext2, reiser) showed the same results. If i use the drive without raid everything works fine. Many Thanks in advance! Best regards, Markus
