Hi list, I am facing a strange behaviour between udev and the raid code here and to be honest I do not know where the problem is. The problem is the following. I have two md devices ARRAY /dev/md0 metadata=0.90 UUID=3b9e371a:f651d170:2a42ebe3:f331026f ARRAY /dev/md/1 metadata=1.00 name=gibson:1 UUID=2f18e1fe:867d891e:501f93be:ea635188 /dev/md/1 is giving me troubles. I am booting using an initramfs. Looking through the initramfs scripts I see that /dev/md/1 gets created by it. The syslog on the other hand shows me this during the boot process. Aug 4 21:23:12 gibson mdadm[3606]: DeviceDisappeared event detected on md device /dev/md/1 Aug 4 21:23:12 gibson mdadm[3606]: NewArray event detected on md device /dev/md1 Apparently the device gets removed and then added as /dev/md1 as a result /dev/md/1 disappears. If I then run mdadm -Ds I see this KERNEL[1280949869.791242] change /devices/virtual/block/md1 (block) KERNEL[1280949869.792353] change /devices/virtual/block/md0 (block) UDEV [1280949869.850176] change /devices/virtual/block/md1 (block) UDEV [1280949870.044863] change /devices/virtual/block/md0 (block) and /dev/md/1 is re-created. Now my question. Why does /dev/md/1 disappear and /dev/md1 gets created? And even if /dev/md1 gets created shouldn't this trigger udev automatically resulting in the creation of /dev/md/1 like running mdadm -Ds does?
