Subject: [RHEL7.9 PATCH 54/71] Change warning message
|
|
|
5bf14f |
|
|
|
5bf14f |
In commit 039b7225e6 ("md: allow creation of mdNNN arrays via
|
|
|
5bf14f |
md_mod/parameters/new_array") support for name like mdNNN
|
|
|
5bf14f |
was added. Special warning, when kernel is unable to handle
|
|
|
5bf14f |
request, was added in commit 7105228e19
|
|
|
5bf14f |
("mdadm/mdopen: create new function create_named_array for
|
|
|
5bf14f |
writing to new_array"), but it was not adequate enough,
|
|
|
5bf14f |
because in this situation mdadm tries to do it in old way.
|
|
|
5bf14f |
This commit changes warning to be more relevant when
|
|
|
5bf14f |
creating RAID container with "/dev/mdNNN" name and mdadm
|
|
|
5bf14f |
back to old approach.
