      "message": "Create global_filter to avoid scan of missing devs\n\nA while back I added an lvm.conf file with a device filter setting\nto try and clean up the LVM hangs in the gate:\n  (commit 0b9e76f280208b5b5ad54bb6fbc4133e63037286)\n\nIt turns out this wasn\u0027t the real problem, the real problem\nis that on an LVS/VGS command LVM  will attempt to open and read\nall potential block devices in /dev to see if they have LVM data\non them.  I initially thought the local filter would keep that\nfrom happening, as it turns out the local filter only limits what\u0027s\nreturned AFTER the actual scan process.  In order to keep the scan\nfrom happening at all, either a global_filter needs to be used or\nlvmetad needs to be running and enabled.\n\nThere are situations in gate tests where /dev/sdX devices are created and\ndeleted and the result is that we hit situations where LVM tries\nto open up devices to check them even if they\u0027ve been removed.  The\nresult is we have a blocking open call from LVM that takes approx\n60 seconds to time out and fail.\n\nUbuntu won\u0027t have a version of lvmetad until Vivid, so for now\nthat just leaves the global_filter as an option.\n\nThis patch adds the filter routine to the end of stack.sh.  We don\u0027t\nwant to put the routine in lib/cinder_backend/lvm like we had it because\nnow we have to set the global filter for all LVM commands on the system.\nSo we put this as one of the last steps in stack.sh and run it if Cinder\nis enabled.  This way we can query PV\u0027s on the system regardless of what\nother services may be running and using LVM and make sure that all of\ntheir devices are added to the filter as well.\n\nAlso, make sure we only set this for Ubuntu as Fedora/RHEL variants\nutilize lvmetad.\n\nThis patch also removes the old change that set the local filter.\n\nDocImpact\nShould add this to recommended config for Cinder on systems\nthat don\u0027t have lvmetad, and recommend lvmetad for those that do.\n\nChange-Id: I5d5c48e188cbb9b4208096736807f082bce524e8\nCloses-Bug: #1373513\n"

      "message": "Auto add a cinder lvm.conf file\n\nWe have a number of issues where LVM scan commands hang during\ntest runs.  Looking closer at this with strace it turns out\nthat what seems to be happening is that we\u0027re scanning all of the\ndevices on the node, this includes the loop devices for swift and\nother projects as well as the Cinder devices that are being attached\nto the system during the test.\n\nThis is particularly messy for example when we issue a VG or LV scan\non a device like /dev/vdb and at the same time issue a detach.  The\nresult is LVM scan commands hanging waiting for timeout.\n\nThis patch adds a function to the cinder_backend/lvm module which\nis called as the last part of cinder init.  If Cinder LVM is in use\nas per cinder.conf this function will copy the default\n/etc/lvm/lvm.conf to /etc/cinder/lvm.conf and use the cinder.conf file\nand PVS to create filters so that ONLY the devices actually being used\nby Cinder are included in scans.\n\nThere are two pieces to this fix; the first is to properly setup an\nlvm.conf file with filters.  The second step is to merge the Cinder\nchange that modifies the Cinder LVM commands to specify the lvm.conf\nfile usage.\n\nThe Cinder part of this fix can be found here:\n    https://review.openstack.org/#/c/148747/\n\nChange-Id: I962b6e21cbfb6f5612b6c973053d86828ca8071a\nPartial-Bug: #1373513\n"
