Subject: [PATCH 36/52] mdadm: Fix mdadm -r remove option regression
|
|
|
|
The commit noted below globally adds a parameter to the -r option but missed
|
|
the fact that -r is used for another purpose: --remove.
|
|
|
|
After that commit, a command such as:
|
|
|
|
mdadm /dev/md0 -r /dev/loop0
|
|
|
|
will do nothing seeing the device parameter will be consumed as a
|
|
argument to the -r option; thus, there will only be one device
|
|
seen one the command line, devs_found will only be 1 and nothing will
|
|
happen.
|
|
|
|
This caused the 01r5integ and 01raid6integ tests to hang indefinitely
|
|
as mdadm did not remove the failed device. With the device not removed,
|
|
it would not be readded. Then the loop waiting for the array status to
|
|
change would loop forever.
|
|
|
|
This commit was recently reverted, but the legitimate fix for the
|
|
monitor operations was still not fixed. So add specific monitor
|
|
short ops to re-fix the --monitor -r option.
|
|

|
Fixes: 190dc029b141 ("Revert "mdadm: fix coredump of mdadm --monitor -r"")
