1990 | If the --bluestore argument is given, a bluestore objectstore | |
1991 | will be used instead of the legacy filestore objectstore. | |
1992 | ||
1993 | When an entire device is prepared for bluestore, two | |
1994 | partitions are created. The first partition is for metadata, | |
1995 | the second partition is for blocks that contain data. | |
1996 | ||
1997 | Unless explicitly specified with --block.db or | |
1998 | --block.wal, the bluestore DB and WAL data is stored on | |
1999 | the main block device. For instance: | |
2000 | ||
2001 | ceph-disk prepare --bluestore /dev/sdc | |
2002 | ||
2003 | Will create | |
2004 | ||
2005 | /dev/sdc1 for osd metadata | |
2006 | /dev/sdc2 for block, db, and wal data (the rest of the disk) | |
2007 | ||
2008 | ||
2009 | If either --block.db or --block.wal are specified to be | |
2010 | the same whole device, they will be created as partition | |
2011 | three and four respectively. For instance: | |
2012 | ||
2013 | ceph-disk prepare --bluestore \\ | |
2014 | --block.db /dev/sdc \\ | |
2015 | --block.wal /dev/sdc \\ | |
2016 | /dev/sdc | |
2017 | ||
2018 | Will create | |
2019 | ||
2020 | /dev/sdc1 for osd metadata | |
2021 | /dev/sdc2 for block (the rest of the disk) | |
2022 | /dev/sdc3 for db | |
