Yes, it is normal.
1. The diskpool gets full
2. Some sessions request backups and end up with mount requests
3. The diskpool is drained and there is some space in it
4. New sessions backup to diskpool while old sessions still wait their 
requests to get satisfied

A possible workaround for this issue is to set maxnummp=0 for offending 
nodes but their backups will tend to fail due to lack of server storage 
space.
The real solution is to scale your diskpool when your nodes scale!!!

hello
 
I guess the subjectline says it all.
When my diskpool gets full the new sessions goes directly to the tapepool,
but when the diskpool is migrated and gets free space the sessions still
wait for mountpoint in my tapepool. 
Is it normal behaviour??
