      "message": "dm: raid456 basic support\n\nThis patch is the skeleton for the DM target that will be\nthe bridge from DM to MD (initially RAID456 and later RAID1).  It\nprovides a way to use device-mapper interfaces to the MD RAID456\ndrivers.\n\nAs with all device-mapper targets, the nominal public interfaces are the\nconstructor (CTR) tables and the status outputs (both STATUSTYPE_INFO\nand STATUSTYPE_TABLE).  The CTR table looks like the following:\n\n1: \u003cs\u003e \u003cl\u003e raid \\\n2:\t\u003craid_type\u003e \u003c#raid_params\u003e \u003craid_params\u003e \\\n3:\t\u003c#raid_devs\u003e \u003cmeta_dev1\u003e \u003cdev1\u003e .. \u003cmeta_devN\u003e \u003cdevN\u003e\n\nLine 1 contains the standard first three arguments to any device-mapper\ntarget - the start, length, and target type fields.  The target type in\nthis case is \"raid\".\n\nLine 2 contains the arguments that define the particular raid\ntype/personality/level, the required arguments for that raid type, and\nany optional arguments.  Possible raid types include: raid4, raid5_la,\nraid5_ls, raid5_rs, raid6_zr, raid6_nr, and raid6_nc.  (again, raid1 is\nplanned for the future.)  The list of required and optional parameters\nis the same for all the current raid types.  The required parameters are\npositional, while the optional parameters are given as key/value pairs.\nThe possible parameters are as follows:\n \u003cchunk_size\u003e\t\tChunk size in sectors.\n [[no]sync]\t\tForce/Prevent RAID initialization\n [rebuild \u003cidx\u003e]\tRebuild the drive indicated by the index\n [daemon_sleep \u003cms\u003e]\tTime between bitmap daemon work to clear bits\n [min_recovery_rate \u003ckB/sec/disk\u003e]\tThrottle RAID initialization\n [max_recovery_rate \u003ckB/sec/disk\u003e]\tThrottle RAID initialization\n [max_write_behind \u003cvalue\u003e]\t\tSee \u0027-write-behind\u003d\u0027 (man mdadm)\n [stripe_cache \u003csectors\u003e]\t\tStripe cache size for higher RAIDs\n\nLine 3 contains the list of devices that compose the array in\nmetadata/data device pairs.  If the metadata is stored separately, a \u0027-\u0027\nis given for the metadata device position.  If a drive has failed or is\nmissing at creation time, a \u0027-\u0027 can be given for both the metadata and\ndata drives for a given position.\n\nExamples:\n# RAID4 - 4 data drives, 1 parity\n# No metadata devices specified to hold superblock/bitmap info\n# Chunk size of 1MiB\n# (Lines separated for easy reading)\n0 1960893648 raid \\\n\traid4 1 2048 \\\n\t5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81\n\n# RAID4 - 4 data drives, 1 parity (no metadata devices)\n# Chunk size of 1MiB, force RAID initialization,\n#\tmin recovery rate at 20 kiB/sec/disk\n0 1960893648 raid \\\n        raid4 4 2048 min_recovery_rate 20 sync\\\n        5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81\n\nPerforming a \u0027dmsetup table\u0027 should display the CTR table used to\nconstruct the mapping (with possible reordering of optional\nparameters).\n\nPerforming a \u0027dmsetup status\u0027 will yield information on the state and\nhealth of the array.  The output is as follows:\n1: \u003cs\u003e \u003cl\u003e raid \\\n2:\t\u003craid_type\u003e \u003c#devices\u003e \u003c1 health char for each dev\u003e \u003cresync_ratio\u003e\n\nLine 1 is standard DM output.  Line 2 is best shown by example:\n\t0 1960893648 raid raid4 5 AAAAA 2/490221568\nHere we can see the RAID type is raid4, there are 5 devices - all of\nwhich are \u0027A\u0027live, and the array is 2/490221568 complete with recovery.\n\nCc: linux-raid@vger.kernel.org\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nSigned-off-by: Jonathan Brassow \u003cjbrassow@redhat.com\u003e\nSigned-off-by: Mike Snitzer \u003csnitzer@redhat.com\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"

      "message": "dm raid1: add userspace log\n\nThis patch contains a device-mapper mirror log module that forwards\nrequests to userspace for processing.\n\nThe structures used for communication between kernel and userspace are\nlocated in include/linux/dm-log-userspace.h.  Due to the frequency,\ndiversity, and 2-way communication nature of the exchanges between\nkernel and userspace, \u0027connector\u0027 was chosen as the interface for\ncommunication.\n\nThe first log implementations written in userspace - \"clustered-disk\"\nand \"clustered-core\" - support clustered shared storage.   A userspace\ndaemon (in the LVM2 source code repository) uses openAIS/corosync to\nprocess requests in an ordered fashion with the rest of the nodes in the\ncluster so as to prevent log state corruption.  Other implementations\nwith no association to LVM or openAIS/corosync, are certainly possible.\n\n(Imagine if two machines are writing to the same region of a mirror.\nThey would both mark the region dirty, but you need a cluster-aware\nentity that can handle properly marking the region clean when they are\ndone.  Otherwise, you might clear the region when the first machine is\ndone, not the second.)\n\nSigned-off-by: Jonathan Brassow \u003cjbrassow@redhat.com\u003e\nCc: Evgeniy Polyakov \u003cjohnpol@2ka.mipt.ru\u003e\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\n"
