So, we run the MD level 6 array (/dev/md1) with journal device on
a plain partition of one of SSD disk (/dev/sdh5) now. See attached files
for more details.
Since then (March 17th), our discussed issue happened "only" three
times. First occurrence was on April 21st, 5 weeks after moving the
journal.
*I can confirm that the issue still persist, but it is definitely less
frequent.*
Could you check if this helps?
