Subject: [PATCH 61/83] Mdmonitor: Omit non-md devices
|
|
|
2ad819 |
|
|
|
2ad819 |
Fix segfault commit [1] introduced check whether given device is
|
|
|
2ad819 |
mddevice, but it happend to terminate Mdmonitor if at least one of given
|
|
|
2ad819 |
devices didn't fulfill that condition. In result Mdmonitor service was
|
|
|
2ad819 |
no longer started on boot (with --scan option) when config contained some
|
|
|
2ad819 |
non-existent array entry.
|
|
|
2ad819 |
|
|
|
2ad819 |
This commit introduces ommiting non-md devices so scan option can still
|
|
|
2ad819 |
be used when config is wrong and allow Mdmonitor service to run on boot.
|
|
|
2ad819 |
|
|
|
2ad819 |
Giving a list of devices to monitor containing non-existing or
|
|
|
2ad819 |
non-md devices will result in monitoring only confirmed mddevices.
