there is 16Gb ssd partition and 50Gb home partition. kernel 5.2 amd64
command eio_cli create -d /dev/sdb5 -s /dev/sda4 -p lru -m wt -c sdb5_cache
behavior is the same with wt or with ro.
in the upstream it seems that similar error was fixed.

Could you please provide #parted -l /dev/sdb and #cat /proc/enhanceio/sdb5_cache/config? Thanks.

I migrated to bcache, but it works noticeably worse. I will try now to reproduce the problem again at a new partition
