Hello, It seems that mdadm/md do not perform proper sanity checks before adding a component to a degraded array. If the size of the new component is just right, the superblock information will overlap with the data area. This will happen without any error indications in the syslog or otherwise.I thought I fixed that.... What versions of Linux kernel and mdadm are you using for your tests?
Linux is 2.6.23.14 with everything md related compiled in (no modules) mdadm - v2.6.4 - 19th October 2007 (latest in debian/sid) Peter
