Booting with disk failure
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
This guide is written with disk failure in mind.
|
||||
|
||||
If disks used in Root on ZFS pool failed, but
|
||||
sufficient redundancy for both root pool and boot pool
|
||||
still exists, the system will still boot normally.
|
||||
|
||||
Swap partition on the failed disk will fail to mount,
|
||||
after an 1m30s timeout.
|
||||
|
||||
This feature is useful for use cases such
|
||||
as an unattended remote server.
|
||||
|
||||
Example:
|
||||
|
||||
- System has disks ``n>1``
|
||||
|
||||
- Installed with mirrored setup
|
||||
|
||||
- Mirrored setup can tolerate up to ``n-1`` disk failures
|
||||
|
||||
- Disconnect one or more disks, keep at least
|
||||
one disk connected
|
||||
|
||||
- System still boots, but fails to mount swap and
|
||||
EFI partition
