Subject: auto start raid0 with no superblock?
Date: Tue, 4 Aug 2009 14:44:52 -0600 [thread overview]
Message-ID: <200908041444.52747.tfjellstrom@shaw.ca> (raw)
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.
