I'm testing out accessing a "Windows DynamicDisk Raid0" array under linux, and for the most part it works very well. My only problem is mdadm will not auto start the array even when I have it setup in mdadm.conf (mdadm is told to auto start all arrays found there). Basically I have to manually run "mdadm --build /dev/md0 --chunk=64 --level=raid0 --raid-devices=4 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1" then "mount /mnt/winraid" when I want to access the filesystem (using ntfs-3g if anyone was wondering). All I get from mdadm/syslog is this: Aug 4 02:43:10 natasha kernel: [ 7.862373] md: md0 stopped. Aug 4 02:43:18 natasha mdadm[3597]: DeviceDisappeared event detected on md device /dev/md0 The reason I'm trying to use non persistent superblocks is I'm assuming trying to save them will damage the windows DynamicDisk metadata in some way. -- Thomas Fjellstrom tfjellstrom@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
