--- Comment #8 from Ojaswin Mujoo (ojaswin.mujoo@ibm.com) ---
Hey Ivan, thanks!=20

Seems like stripe mount option is automatically added if the filesystem is =
made
using stride or stripe-width options during mkfs time.=20

Can you kindly perform the below steps as well to further help narrow this
issue down:

1. Mount FS with the usual options (including using stripe=3D32752).=20
2. Once mounted, run:

$ echo "0" > /sys/fs/ext4/sdb2/mb_best_avail_max_trim_order

This might need sudo. Basically this disables one of the allocator feature =
that
was added in 6.5.

3. Run the workload again and see if the issue is still visible.

Regards,
ojaswin
