Description

The truncate operation consistently leads to LFSCK reporting repaired_inconsistent_owner. This issue occurs in Lustre version 2.15.6 (other versions not tested)

Steps to Reproduce:

1. sudo chown -R $USER: /mnt/lustre
2. lfs setstripe -o 0,1 /mnt/lustre
3. touch /mnt/lustre/file1
4. truncate -s 1M /mnt/lustre/file1
5. sudo lctl lfsck_start -A -r -t all -C -c -o -d

Results:
repaired_inconsistent_owner: 2
This issue appears to be consistently reproducible following the steps outlined above. Truncating to other sizes (e.g. truncate -s 1048596) also gives inconsistent owner issue.

Note that truncating files to a smaller size works fine and behaves as expected.
