Subject: [PATCH 1/2] Filesystem: respect udevd need time to create UUID
|
|
|
9cf66a |
symlinks
|
|
|
9cf66a |
|
|
|
9cf66a |
To refresh the filesystem UUID, there is a race condition. partprobe
|
|
|
9cf66a |
might return before the UUID symlink get created. Particularly, when the
|
|
|
9cf66a |
system has many devices, the udev daemon could need visible time to
|
|
|
9cf66a |
process the udev event queue. Hence, wait udev for a moment.

Subject: [PATCH 2/2] Filesystem: add trigger_udev_rules_if_need() for -U, -L,
|
|
|
9cf66a |
or /dev/xxx device
|
|
|
9cf66a |
|
|
|
9cf66a |
DEVICE parameter of this RA accepts "-U <uuid>" and "-L <label>" in
|
|
|
9cf66a |
addition to "/dev/xxx". Let's add a new function
|
|
|
9cf66a |
trigger_udev_rules_if_needed() to accommodate them all.
|
|
|
9cf66a |
|
|
|
9cf66a |
It is useful in the case a fresh filesystem is just created from another
|
|
|
9cf66a |
node on the shared storage, and is not visible yet.
