Anyway, I am having problems with a raid10 sandbox setup consisting of 4 loopback devices. To make a long story short: I created a raid10 array with all these 4 devices (loop0-loop3) then I set two devices faulty, removed them .. checked if I can still write to the array (which I could, so I/O errors, nothing in dmesg): BUT - here it comes: once I am trying to (re)add them (I zero'ed the superblock before) they're only getting added as spares and the array will not sync. Here's the logfile with mdadm -D /dev/md0 in between so one can see what is going on: http://paste.debian.net/31758/ Any ideas? PS: Please CC to me since I am not subscribed. regards, Patrick
