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.
