Description Venky Shankar 2023-01-17 04:34:42 UTC 
Description of problem:

After commit 28227872295ae657a0d26a3f004c54c41794db18 mds: automatically fragment stray dirs
stray dirs are allowed to be fragment.

But scan_stray_dir doesn't walk through all fragments of the stray inodes correctly.
It doesn't reset next.frag after each run of stray dir inode.
Therefore, next stray inode will start from the last fragment of previous stray inode, and the preceding fragments are all skipped.


Version-Release number of selected component (if applicable):
5.2

How reproducible:
Always

Steps to Reproduce:
Delete huge number of files in cephfs to fill up the stray directory and restart the MDS whilst the inodes hang around in stray. Not all stray inodes would get evaluated.

Actual results:
MDS should correct evaluate stray directory inodes on restart.
