Applying operations or just scanning the partitions in GParted was causing all stopped Linux Software RAID arrays to be automatically started. This is not new with this patch set, but as a result of the following behaviour which has existed for a long time. Chain of events goes likes this: 1) Gparted calls commit_to_os() to update the kernel with the new partition table; 2) Libparted calls ioctl() BLKPG_DEL_PARTITION on every partition to delete every partition from the kernel. Succeeds on non-busy partitions only; 3) Kernel emits udev partition remove event on every removed partition; 4) Libparted calls ioctl() BLKPG_ADD_PARTITION on every non-busy partition to re-add the partition to the kernel; 5) Kernel emits udev partition add event on every added partition; 6) Udev rule: SUBSYSTEM=="block", ACTION=="add", ENV{ID_FS_TYPE}=="linux_raid_member", \ RUN+="/sbin/mdadm -I $tempnode" from either /lib/udef/rules.d/64-md-raid.rules or .../65-md-incremental.rules incrementally starts the member in a Linux Software RAID array. Fix by temporarily adding blank override rules files which does nothing, so that when the udev add and remove events for Linux Software RAID array member partitions fire nothing is done; but only when required. Note that really old versions of udev don't have rules to incrementally start array members and some distributions comment out such rules. Bug #709640 - Linux Swap Suspend and Software RAID partitions not recognised

# Name: gparted
|
|
# Purpose: Perform appropriate startup of GParted executable gpartedbin.
|
|
#
|
|
# The purpose of these startup methods is to prevent
|
|
# devices from being automounted, and to ensure only one
|
|
# instance of GParted is running. File system problems can
|
|
# occur if devices are mounted prior to the completion of
|
|
# GParted's operations, or if multiple partition editing
|
|
# tools are in use concurrently.
