commit b1aab5d0e12e433b714e39f78945baf16e508a41 Author: James Page <[email protected]> Date: Fri May 15 17:00:25 2020 +0100 Trigger udev rescan if pv_dev disappears Workaround for kernel by in Ubuntu 20.04 LTS. When using by-dname device paths with MAAS and bcache, the pvcreate operation results in the by-dname entry for the block device being deleted. The subsequent vgcreate then fails as the path cannot be found. Trigger a rescan of block devices if the pv_dev path does not exists after the pvcreate operation.
