            "content": "pvmove  moves  the allocated physical extents (PEs) on a source PV to one or more destination\nPVs.  You can optionally specify a source LV in which case only extents used by that LV  will\nbe moved to free (or specified) extents on the destination PV. If no destination PV is speci‐\nfied, the normal allocation rules for the VG are used.\n\nIf pvmove is interrupted for any reason (e.g. the machine  crashes)  then  run  pvmove  again\nwithout any PV arguments to restart any operations that were in progress from the last check‐\npoint. Alternatively, use the abort option at any time to abort the operation. The  resulting\nlocation of LVs after an abort depends on whether the atomic option was used.\n\nMore  than one pvmove can run concurrently if they are moving data from different source PVs,\nbut additional pvmoves will ignore any LVs already in the process of being changed,  so  some\ndata might not get moved.\n",

            "content": "pvmove works as follows:\n\n1. A temporary 'pvmove' LV is created to store details of all the data movements required.\n\n2.  Every LV in the VG is searched for contiguous data that need moving according to the com‐\nmand line arguments.  For each piece of data found, a new segment is added to the end of  the\npvmove LV.  This segment takes the form of a temporary mirror to copy the data from the orig‐\ninal location to a newly allocated location.  The original LV is updated to use the new  tem‐\nporary mirror segment in the pvmove LV instead of accessing the data directly.\n\n3. The VG metadata is updated on disk.\n\n4. The first segment of the pvmove LV is activated and starts to mirror the first part of the\ndata.  Only one segment is mirrored at once as this is usually more efficient.\n\n5. A daemon repeatedly checks progress at the specified time interval.  When it detects  that\nthe  first  temporary  mirror is in sync, it breaks that mirror so that only the new location\nfor that data gets used and writes a checkpoint into the VG metadata on disk.  Then it  acti‐\nvates the mirror for the next segment of the pvmove LV.\n\n6.  When  there are no more segments left to be mirrored, the temporary LV is removed and the\nVG metadata is updated so that the LVs reflect the new data locations.\n\nNote that this new process cannot support the original LVM1 type of on-disk metadata.   Meta‐\ndata can be converted using vgconvert(8).\n\nIf the --atomic option is used, a slightly different approach is used for the move.  Again, a\ntemporary 'pvmove' LV is created to store the details of all  the  data  movements  required.\nThis  temporary  LV contains all the segments of the various LVs that need to be moved.  How‐\never, in this case, an identical LV is allocated that contains the same  number  of  segments\nand  a mirror is created to copy the contents from the first temporary LV to the second.  Af‐\nter a complete copy is made, the temporary LVs are removed, leaving behind  the  segments  on\nthe  destination  PV.  If an abort is issued during the move, all LVs being moved will remain\non the source PV.\n\n",
