Then passing\na credential and object_id info at the io_state level, private for each\ninode. It would also devise this contraption of rotating the device table\nview for each inode-\u003eino to spread out the device usage.\n\nThis is not compatible with the pnfs-objects standard, demanding that\neach inode can have it\u0027s own layout-info, device-table, and each object\ncomponent it\u0027s own pid, oid and creds.\n\nSo: Bring exofs raid engine to be usable for generic pnfs-objects use by:\n\n* Define an exofs_comp structure that holds obj_id and credential info.\n\n* Break up exofs_layout struct to an exofs_components structure that holds a\n  possible array of exofs_comp and the array of devices + the size of the\n  arrays.\n\n* Add a \"comps\" parameter to get_io_state() that specifies the ids creds\n  and device array to use for each IO.\n\n  This enables to keep the layout global, but the device-table view, creds\n  and IDs at the inode level. It only adds two 64bit to each inode, since\n  some of these members already existed in another form.\n\n* ios raid engine now access layout-info and comps-info through the passed\n  pointers. Everything is pre-prepared by caller for generic access of\n  these structures and arrays.\n\nAt the exofs Level:\n\n* Super block holds an exofs_components struct that holds the device\n  array, previously in layout. The devices there are in device-table\n  order. The device-array is twice bigger and repeats the device-table\n  twice so now each inode\u0027s device array can point to a random device\n  and have a round-robin view of the table, making it compatible to\n  previous exofs versions.\n\n* Each inode has an exofs_components struct that is initialized at\n  load time, with it\u0027s own view of the device table IDs and creds.\n  When doing IO this gets passed to the io_state together with the\n  layout.\n\nWhile preforming this change. Bugs where found where credentials with the\nwrong IDs where used to access the different SB objects (super.c). As well\nas some dead code. It was never noticed because the target we use does not\ncheck the credentials.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"

The call to exofs_write_super from\nexofs_put_super is also removed because the VFS always calls\n-\u003esync_fs before calling -\u003eput_super twice.\n\nTo stay backward-and-forward compatible we also write the old\ns_nextid in the super_block object at unmount, and support zero\nlength attribute on mount.\n\nThis also fixes a BUG where in layouts when group_width was not\na divisor of EXOFS_SUPER_ID (0x10000) the s_nextid was not read\nfrom the device it was written to. Because of the sliding window\nlayout trick, and because the read was always done from the 0\ndevice but the write was done via the raid engine that might slide\nthe device view. Now we read and write through the raid engine.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"

Including variable sized\nstripe_unit.\n\nSome limits:\n* stripe_unit must be a multiple of PAGE_SIZE\n* stripe_unit * stripe_count is maximum upto 32-bit (4Gb)\n\nTested RAID0 over mirrors, RAID0 only, mirrors only. All check.\n\nDesign notes:\n* I\u0027m not using a vectored raid-engine mechanism yet. Following the\n  pnfs-objects-layout data-map structure, \"Mirror\" is just a private\n  case of \"group_width\" \u003d\u003d 1, and RAID0 is a private case of\n  \"Mirrors\" \u003d\u003d 1. The performance lose of the general case over the\n  particular special case optimization is totally negligible, also\n  considering the extra code size.\n\n* In general I added a prepare_stripes() stage that divides the\n  to-be-io pages to the participating devices, the previous\n  exofs_ios_write/read, now becomes _write/read_mirrors and a new\n  write/read upper layer loops on all devices calling\n  _write/read_mirrors. Effectively the prepare_stripes stage is the all\n  secret.\n  Also truncate need fixing to accommodate for striping.\n\n* In a RAID0 arrangement, in a regular usage scenario, if all inode\n  layouts will start at the same device, the small files fill up the\n  first device and the later devices stay empty, the farther the device\n  the emptier it is.\n\n  To fix that, each inode will start at a different stripe_unit,\n  according to it\u0027s obj_id modulus number-of-stripe-units. And\n  will then span all stripe-units in the same incrementing order\n  wrapping back to the beginning of the device table. We call it\n  a stripe-units moving window.\n\n  Special consideration was taken to keep all devices in a mirror\n  arrangement identical. So a broken osd-device could just be cloned\n  from one of the mirrors and no FS scrubbing is needed. (We do that\n  by rotating stripe-unit at a time and not a single device at a time.)\n\nTODO:\n We no longer verify object_length \u003d\u003d inode-\u003ei_size in exofs_iget.\n (since i_size is stripped on multiple objects now).\n I should introduce a multiple-device attribute reading, and use\n it in exofs_iget.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"

      "message": "exofs: Multi-device mirror support\n\nThis patch changes on-disk format, it is accompanied with a parallel\npatch to mkfs.exofs that enables multi-device capabilities.\n\nAfter this patch, old exofs will refuse to mount a new formatted FS and\nnew exofs will refuse an old format. This is done by moving the magic\nfield offset inside the FSCB. A new FSCB *version* field was added. In\nthe future, exofs will refuse to mount unmatched FSCB version. To\nup-grade or down-grade an exofs one must use mkfs.exofs --upgrade option\nbefore mounting.\n\nIntroduced, a new object that contains a *device-table*. This object\ncontains the default *data-map* and a linear array of devices\ninformation, which identifies the devices used in the filesystem. This\nobject is only written to offline by mkfs.exofs. This is why it is kept\nseparate from the FSCB, since the later is written to while mounted.\n\nSame partition number, same object number is used on all devices only\nthe device varies.\n\n* define the new format, then load the device table on mount time make\n  sure every thing is supported.\n\n* Change I/O engine to now support Mirror IO, .i.e write same data\n  to multiple devices, read from a random device to spread the\n  read-load from multiple clients (TODO: stripe read)\n\nImplementation notes:\n A few points introduced in previous patch should be mentioned here:\n\n* Special care was made so absolutlly all operation that have any chance\n  of failing are done before any osd-request is executed. This is to\n  minimize the need for a data consistency recovery, to only real IO\n  errors.\n\n* Each IO state has a kref. It starts at 1, any osd-request executed\n  will increment the kref, finally when all are executed the first ref\n  is dropped. At IO-done, each request completion decrements the kref,\n  the last one to return executes the internal _last_io() routine.\n  _last_io() will call the registered io_state_done. On sync mode a\n  caller does not supply a done method, indicating a synchronous\n  request, the caller is put to sleep and a special io_state_done is\n  registered that will awaken the caller. Though also in sync mode all\n  operations are executed in parallel.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"

      "message": "exofs: Move all operations to an io_engine\n\nIn anticipation for multi-device operations, we separate osd operations\ninto an abstract I/O API. Currently only one device is used but later\nwhen adding more devices, we will drive all devices in parallel according\nto a \"data_map\" that describes how data is arranged on multiple devices.\nThe file system level operates, like before, as if there is one object\n(inode-number) and an i_size. The io engine will split this to the same\nobject-number but on multiple device.\n\nAt first we introduce Mirror (raid 1) layout. But at the final outcome\nwe intend to fully implement the pNFS-Objects data-map, including\nraid 0,4,5,6 over mirrored devices, over multiple device-groups. And\nmore. See: http://tools.ietf.org/html/draft-ietf-nfsv4-pnfs-obj-12\n\n* Define an io_state based API for accessing osd storage devices\n  in an abstract way.\n  Usage:\n\tFirst a caller allocates an io state with:\n\t\texofs_get_io_state(struct exofs_sb_info *sbi,\n\t\t\t\t   struct exofs_io_state** ios);\n\n\tThen calles one of:\n\t\texofs_sbi_create(struct exofs_io_state *ios);\n\t\texofs_sbi_remove(struct exofs_io_state *ios);\n\t\texofs_sbi_write(struct exofs_io_state *ios);\n\t\texofs_sbi_read(struct exofs_io_state *ios);\n\t\texofs_oi_truncate(struct exofs_i_info *oi, u64 new_len);\n\n\tAnd when done\n\t\texofs_put_io_state(struct exofs_io_state *ios);\n\n* Convert all source files to use this new API\n* Convert from bio_alloc to bio_kmalloc\n* In io engine we make use of the now fixed osd_req_decode_sense\n\nThere are no functional changes or on disk additions after this patch.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n"
