This is an example of the --export output:
# mdadm --detail --export /dev/md127
MD_DEVICES=3
MD_METADATA=1.2
MD_UUID=70bc1acd:f879f9cd:dca76d79:d9ce624a
MD_DEVNAME=debian:R5
MD_NAME=debian:R5
MD_DEVICE_dev_sdc_ROLE=spare
MD_DEVICE_dev_sdc_DEV=/dev/sdc
MD_DEVICE_dev_sdd_ROLE=spare
MD_DEVICE_dev_sdd_DEV=/dev/sdd
MD_DEVICE_dev_sdb_ROLE=spare
MD_DEVICE_dev_sdb_DEV=/dev/sdb
This is the same command in "normal" format-output:
# mdadm --detail /dev/md127
/dev/md127:
Version : 1.2
Raid Level : raid5
Total Devices : 3
Persistence : Superblock is persistent
State : inactive
Working Devices : 3
Name : debian:R5
UUID : 70bc1acd:f879f9cd:dca76d79:d9ce624a
Events : 358
Number Major Minor RaidDevice
- 8 32 - /dev/sdc
- 8 48 - /dev/sdd
- 8 16 - /dev/sdb
It would be nice if the --export included the properties "Raid Level",
"State", "Persistence" (the first two most important).
Another thing, is it correct that "MD_DEVNAME" and "MD_NAME" should be the same?
Or perhaps "MD_NAME" should show the kernel/Device-Mapper name e.g.
"md127", that would be helpful (by the way, what do you call this mdxx
name?)
Thanks
