Grumble, it's the same, just for a different allocation group:
253,2 0 6514 25.375884394 744 Q R 707526656 + 8 [nfsd]
9,0 0 5451 25.375887257 744 A R 749576576 + 8 <- (253,2)
707526
656
9,0 0 5452 25.375888584 744 Q R 749576576 + 8 [nfsd]
8,16 0 17311 25.375891308 744 A R 749576639 + 8 <- (8,17)
7495765
76
8,16 0 17312 25.375892077 744 Q R 749576639 + 8 [nfsd]
8,16 0 17313 25.375894381 744 G R 749576639 + 8 [nfsd]
8,16 0 17314 25.375895918 744 P N [nfsd]
8,16 0 17315 25.375898572 744 I R 749576639 + 8 [nfsd]
8,16 0 17316 25.375900038 744 U N [nfsd] 1
8,16 0 17317 25.375901715 744 D R 749576639 + 8 [nfsd]
Let's try the following:
for (( i = 0; i < 25293; i++ )); do
dd if=/dev/dm-2 of=/dev/null bs=4k count=1 skip=$(($i*32768))
done
Again run it before and after the hang. If it finishes even after the hang,
check whether nfsd is still hung.
