I compiled device-mapper.1.00.21 and dmraid-1.0.0.rc6 The compile for device mapper and dmraid appeared to go just fine. However when I do a 'dmraid -ay' I get the message ERROR: sil: invalid metadata checksum on /dev/sdb ERROR: sil: invalid metadata checksum on /dev/sdb ERROR: sil: invalid metadata checksum on /dev/sdb ERROR: sil: invalid metadata checksum on /dev/sdb In /dev/mapper I have control sil_afadbgdebbdeb sil_afadbgdebbdeb1 There are supposed to be two ntfs partitions on the raid on /dev/sda and /dev/sdb When I mount the drive sil_afadbgdebbdeb1 sudo mount -t ntfs -o users,owner,ro,umask=00 /dev/mapper/sil_afadbgdebbdeb1 /windows/h and do an ls I get ls: reading directory /windows/h: Input/output error I'm running ubuntu horey 5.04 with the 2.6.10-5-k7 kernel. I'm running an asus A7N8X Deluxe with the Sil 3112A Controller with two WD 160 7200 sata drives on them. They are raided together and partitioned into a 260 and 60 gig ntfs partitions made by windows xp sp2. I have 2 maxtor 200 7200 ata drives where I have winxp duel booting with ubuntu. What can I do to get this working, hopefully without needing to destroy the data that is already on the raid? __________________________________ Do you Yahoo!? Yahoo!
