Subject: [RHEL7.8 PATCH V2 34/47] imsm: close removed drive fd.
|
|

f9a9f5 |
When member drive fails, managemon prepares metadata update and adds
|
|
|
f9a9f5 |
the drive to disk_mgmt_list with DISK_REMOVE flag. It fills only
|
|
|
f9a9f5 |
minor and major. It is enough to recognize the device later.
|
|
|
f9a9f5 |
|
|
|
f9a9f5 |
Monitor thread while processing this update will remove the drive from
|
|
|
f9a9f5 |
super only if it is a spare. It never removes failed member from
|
|
|
f9a9f5 |
disks list. As a result, it still keeps opened descriptor to
|
|
|
f9a9f5 |
non-existing device.
|
|
|
f9a9f5 |
|
|
|
f9a9f5 |
If removed drive is not a spare fill fd in disk_cfg structure
|
|
|
f9a9f5 |
(prepared by managemon), monitor will close fd during freeing it.
|
|
|
f9a9f5 |
|
|
|
f9a9f5 |
Also set this drive fd to -1 in super to avoid double closing because
|
|
|
f9a9f5 |
monitor will close the fd (if needed) while replacing removed drive
|
|
|
f9a9f5 |
in array.
