Array Information & Maintenance Options: Critical Status
Arrays in the
Critical
status can be accessed and utilized, but are no longer fault
tolerant. A Critical array should be rebuilt as soon as possible to restore redundancy.
A critical status array has all the normal status options except the following:
•
The Array can no longer be renamed
•
Add Disk
replaces the
Verify Disk
option
Once the array status changes to critical, the faulty disk will be taken offline and you
can either:
•
Reinsert the same disk
•
Insert new disk
Reinserting the same disk should trigger the rebuilding status, since data on the disk
would be recognized.
If you insert a new disk, clicking
Add Disk
will give you the option to select that disk
and add it to the array.
If a spare disk is available, an array that has entered the critical state will begin
rebuilding using the next available spare disk.
