Hmm, good thought, but I don't think that would be it, since his mdstat is showing 2 raid-disks for each array. David, could you send the rest of your log from the time you create the array until after the hot add? I'm wondering what's in the log when the hot add is done. Are there errors? Also, would it be possible to run "mdadm --examine /dev/sd[ab]3" and/or run this: perl -e '$io_num = 0x0913; open (FD, "/dev/md2") or die "open: $!"; ioctl(FD, $io_num, $null) or die "ioctl: $!";' and send the log output, so we can see what's in the superblocks? -- Paul
