Hello people, we have been experiencing an issue with lvm2-thin on
_some_ of our production servers where out of nowhere
lvm2/device-mapper starts spamming error logs and I can't really seem
to trace down the root cause.
This is what the logs look like;
Oct 9 06:25:02 U5bW8JT7 lvm[8020]: device-mapper: waitevent ioctl on
LVM-CP5Gw8QrWLqwhBcJL87R1mc9Q9KTBtQQmOowipTAFuM7hqzHz6pRVvUaNO9FGzeq-tpool
failed: Inappropriate ioctl for device
Oct 9 06:25:02 U5bW8JT7 lvm[8020]: waitevent: dm_task_run failed:
Inappropriate ioctl for device
Hi
Have you considered to try using kernel & lvm2 from the more modern age where
the 'nvme' storage actually become a regularly available commodity hw ?
I'd have guess your issue likely already has been solved.
Otherwise if you do want to do a hunt for a particular IO - use 'blktrace'
tool - likely on tpool_tdata (or tpool_tmeta) volume.
