Don Brady 39fc0cb557 Add support for devid and phys_path keys in vdev disk labels ... This is foundational work for ZED. Updates a leaf vdev's persistent device strings on Linux platform * only applies for a dedicated leaf vdev (aka whole disk) * updated during pool create|add|attach|import * used for matching device matching during auto-{online,expand,replace} * stored in a leaf disk config label (i.e. alongside 'path' NVP) * can opt-out using env var ZFS_VDEV_DEVID_OPT_OUT=YES Some examples: path: '/dev/sdb1' devid: 'scsi-350000394a8ca4fbc-part1' phys_path: 'pci-0000:04:00.0-sas-0x50000394a8ca4fbf-lun-0' path: '/dev/mapper/mpatha' devid: 'dm-uuid-mpath-35000c5006304de3f' Signed-off-by: Don Brady <don.brady@intel.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #2856 Closes #3978 Closes #4416		2016-03-31 13:45:53 -07:00
