Hi Folks!
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
