For this reason, md will normally refuse to start such an array. This
requires the sysadmin to take action to explicitly start the array
-desipite possible corruption. This is normally done with
+despite possible corruption. This is normally done with
mdadm --assemble --force ....
This option is not really available if the array has the root
raid levels that involve striping (1,4,5,6,10). The address space
of the array is conceptually divided into chunks and consecutive
chunks are striped onto neighbouring devices.
- The size should be atleast PAGE_SIZE (4k) and should be a power
+ The size should be at least PAGE_SIZE (4k) and should be a power
of 2. This can only be set while assembling an array
component_size
safe_mode_delay
When an md array has seen no write requests for a certain period
of time, it will be marked as 'clean'. When another write
- request arrive, the array is marked as 'dirty' before the write
- commenses. This is known as 'safe_mode'.
+ request arrives, the array is marked as 'dirty' before the write
+ commences. This is known as 'safe_mode'.
The 'certain period' is controlled by this file which stores the
period as a number of seconds. The default is 200msec (0.200).
Writing a value of 0 disables safemode.
This applies only to raid1 arrays.
spare - device is working, but not a full member.
This includes spares that are in the process
- of being recoverred to
- This list make grow in future.
+ of being recovered to
+ This list may grow in future.
This can be written to.
Writing "faulty" simulates a failure on the device.
Writing "remove" removes the device from the array.
This gives the role that the device has in the array. It will
either be 'none' if the device is not active in the array
(i.e. is a spare or has failed) or an integer less than the
- 'raid_disks' number for the array indicating which possition
+ 'raid_disks' number for the array indicating which position
it currently fills. This can only be set while assembling an
array. A device for which this is set is assumed to be working.
rdNN
-where 'NN' is the possition in the array, starting from 0.
+where 'NN' is the position in the array, starting from 0.
So for a 3 drive array there will be rd0, rd1, rd2.
These are symbolic links to the appropriate 'dev-XXX' entry.
Thus, for example,
