Subject: [RHEL7.8 PATCH V2 34/47] imsm: close removed drive fd.
|
|
|
|
When member drive fails, managemon prepares metadata update and adds
|
|
the drive to disk_mgmt_list with DISK_REMOVE flag. It fills only
|
|
minor and major. It is enough to recognize the device later.
|
|
|
|
Monitor thread while processing this update will remove the drive from
|
|
super only if it is a spare. It never removes failed member from
|
|
disks list. As a result, it still keeps opened descriptor to
|
|
non-existing device.
|
|
|
|
If removed drive is not a spare fill fd in disk_cfg structure
|
|
(prepared by managemon), monitor will close fd during freeing it.
|
|
|
|
Also set this drive fd to -1 in super to avoid double closing because
|
|
monitor will close the fd (if needed) while replacing removed drive
|
|
in array.
