[LU-3102] kernel BUG at fs/jbd2/transaction.c:1033

Related — Tue, 14 Dec 2021 22:58:29 +0000

While testing wide-striping by creating 200 osts per oss, 2 oss, I ran the following. Note that I see the stripe count to 500 which is more than 400 total osts.

while true; do
rm -rf /mnt/lustre/dir$(hostname)
for i in $(seq 1 500); do
DIR=/mnt/lustre/dir$(hostname)/dir$i
mkdir -p $DIR
lfs setstripe -c $i $DIR
touch $DIR/lustre
ls -l $DIR/lustre
lfs getstripe $DIR > /dev/null
done
done
