scripts: introduce blkdeactivate blkdeactivate - utility to deactivate block devices Traverses the tree of block devices and tries to deactivate them. Currently, it supports device-mapper-based devices together with LVM. See man/blkdeactivate.8 for more info. It is targeted for use during shutdown to properly deactivate the whole block device stack - systemd and init scripts are provided as well. However, it might be used directly on command line too. Please, see the commentary at the top of the blkdeactivate script for dependencies and versions of other utilities required. 2012-10-12 16:37:57 +04:00			`[Unit]`

systemd: blk-availability.service: add After=iscsi-shutdown.service The iscsi-shutdown.service is the one responsible for logging out iscsi sessions so blk-availability.service (running the blkdeactivate script) should be run before that on shutdown (so we need to use After=iscsi-shutdown.service because "After" relates to starting the service and the opposite order is automatically applied on stopping the service at shutdown). 2015-03-13 14:05:47 +03:00			`After=lvm2-activation.service lvm2-lvmetad.service iscsi-shutdown.service iscsi.service iscsid.service fcoe.service`

blkdeactivate: add -m\|--mpathoption disablequeueing and use it for blk-availability systemd service and initscript blkdeactivate -m disablequeueing causes "multipathd disablequeueing maps" call inside blkdeactivate script before deactivating devices. This avoids a situation where blkdeactivate may wait for paths to appear if multipath is set to queueing and there's a stack of other devices and/or mount points on top of such multipath device.
