public bool md_create (string name, string[] devices, MDCreate? optargs) throws Error
create a Linux md (RAID) device
Create a Linux md (RAID) device named name on the devices in the list devices.
The optional parameters are:
missingbitmap A bitmap of missing devices. If a bit is set it means that a missing device is added to the array. The least
significant bit corresponds to the first device in the array.
As examples:
If "devices = ["/dev/sda"]" and "missingbitmap = 0x1" then the resulting array would be "[<missing>, "/dev/sda"]".
If "devices = ["/dev/sda"]" and "missingbitmap = 0x2" then the resulting array would be "["/dev/sda", <missing>]".
This defaults to @0 (no missing devices).
The length of devices + the number of bits set in missingbitmap must equal nrdevices + spare
.
nrdevices The number of active RAID devices.
If not set, this defaults to the length of devices plus the number of bits set in missingbitmap.
spare The number of spare devices.
If not set, this defaults to @0.
chunk The chunk size in bytes.
level The RAID level, which can be one of: *linear*, *raid0*, *0*, *stripe*, *raid1*, *1*, *mirror*, *raid4*, *4*, *raid5*,
*5*, *raid6*, *6*, *raid10*, *10*. Some of these are synonymous, and more levels may be added in future.
If not set, this defaults to raid1.
This function depends on the feature "mdadm". See also feature_available .
