/devices/pseudo/md - detecting problems?

Got an informix DB that won't start because DB chunk is offline. Its a raw device. See below:-

lrwxrwxrwx   1 root     root          29 Feb  6  2013 /dev/DB -> /devices/pseudo/md@0:0,10,raw

How do I tell what that refers to? I've checked metadb and metastat and cant see any issues?

Can you show us the output from ls -l /devices/pseudo/md@0:0,10,raw ?

You might get a device major & minor node (rather than a size) so you might be able to search /dev for any special files that match that.

Regards,
Robin
