Hello,
the filter is:
filter = [ "r|/dev/.*/by-path/.*|", "r|/dev/.*/by-id/.*|",
"r|/dev/fd.*|", "r|/dev/cdrom|", "a/.*/" ]
if filter doesn't contain "a/.*/":
- pvcreate, vgcreate & vgextend use regex filter to reject the disk.
(correct logic)
if filter contains "a/.*/":
- regex fileter pass the disk under pvcreate/vgcreate, create successfully.
- regex filter reject the disk under vgextend. (wrong. should create
successfuly)
- vgextend should do the same action as pvcreate/vgcreate.
log as below (with filter contain: "a/.*/"):
