Description

I hit this bug when I do the following thing:

On a fresh lustre env:
1. lfs setstripe -c -1 /mnt/lustre
2. dd if=/dev/zero of=/mnt/lustre/testfile bs=1M count=1500 oflag=direct
3. do rewrite: dd if=/dev/zero of=/mnt/lustre/testfile bs=1M count=1500 oflag=direct

it hit this bug, and the stack trace on the OSS is:
