250.0. "region log merge question" by EVTAI1::BROCHARD (Manuel Brochard - French CSC) Wed Apr 23 1997 03:18

    
    Hi,
    
    	One customer has a very old and "stable" config with ultrix
    shadowing running on his 5240, Ultrix v4.3
    	
    	the last Creation date is 2 Aug 1995
    
    Each Sunday, he does a shutdown/reboot. From 2 years, no special problems..
    
    	But last sunday He got a reboot time :
    
>   shadow: Beginning region log merge on set /dev/shd9c with 8 dirty regions
and 
>   shadow: Beginning region log merge on set /dev/shd11c with 4 dirty regions
    
    
    	After a short time, everythings is OK, the both shadows are present 
    	with 2 members each.
    	shdls -v shows  0 or 1 dirty region and all I/O seems Ok..
    
    	Does the system need special attention ?
    	fsck on /dev/rshd9c ? 
    	other.. ?
    
     Thanks for info,
    
    	Manuel.
