README.Debian for megaide-status package
|
||||
----------------------------------------
|
||||
|
||||
Required configuration:
|
||||
-----------------------
|
||||
|
||||
This software uses informations from /proc/megaide/.
|
||||
However the megaide kernel module report all disk controller ports, even if
|
||||
there are not used.
|
||||
So there is now way to figure out if a disk is not used or if it's offline.
|
||||
|
||||
That's why I added /etc/megaide-status.conf configuration file which should
|
||||
be filled with "in-use" disks ids.
|
||||
|
||||
The syntaxe is 'c<controlleride>u<logicalvolid>p<physicaldiskid>'.
|
||||
In exemple, first disk on second logicial volume and third controller is:
|
||||
c2u1p0
|
||||
|
||||
The default configuration file is suitable for regular SATA systems with
|
||||
only one RAID array.
|
||||
|
||||
Possible configuration:
|
||||
-----------------------
|
||||
|
||||
If you want to change the default configuration of the init script you
|
||||
can create the file /etc/default/megaide-statusd and specify the following
|
||||
values.
|
||||
|
||||
MAILTO=
|
||||
PERIOD=
|
||||
REMIND=
|
||||
|
||||
Use MAILTO to specify which user shall get the status mails
|
||||
(default is root).
|
||||
|
||||
With PERIOD you can fix the seconds between each check.
|
||||
|
||||
And REMIND specifies the seconds between each reminder.
