управлять MD-устройствами, также известными как Linux Software RAID (manage MD devices aka Linux Software RAID)
Файлы (Files)
/proc/mdstat
If you're using the /proc filesystem, /proc/mdstat lists all
active md devices with information about them. mdadm uses this
to find arrays when --scan is given in Misc mode, and to monitor
array reconstruction on Monitor mode.
/etc/mdadm.conf
The config file lists which devices may be scanned to see if they
contain MD super block, and gives identifying information (e.g.
UUID) about known MD arrays. See mdadm.conf(5) for more details.
/etc/mdadm.conf.d
A directory containing configuration files which are read in
lexical order.
/run/mdadm/map
When --incremental mode is used, this file gets a list of arrays
currently being created.
