.Sh RECOVERING
The GEOM class PART supports recovering of partition tables only for GPT.
The GEOM PART class supports recovering of partition tables only for GPT.
The GUID partition table has a primary and secondary (backup) copy of
metadata for redundance.
They are stored in the begining and in the end of device respectively.
Therefore it is acceptable to have some corruptions in the metadata that
are not fatal to work with GPT.
When kernel detects corrupt metadata it marks this table as corrupt and
reports about corruption.
Any changes in corrupt table are prohibited except
metadata for redundance, these are stored at the begining and the end
of the device respectively.
As a result of having two copies, it is acceptable to have some corruption
within the metadata that is not fatal to the working of GPT.
When the kernel detects corrupt metadata it marks this table as corrupt and
reports the corruption.
Any operations on corrupt tables are prohibited except for
.Cm destroy
and
.Cm recover .
.Pp
In case when only first sector is corrupt kernel can not detect GPT even
if partition table is not corrupt.
You can write protective MBR with
If the first sector of a provider is corrupt, the kernel can not detect GPT
even if partition table itself is not corrupt.
You can rewrite the protective MBR using the
.Xr dd 1
command to restore ability of GPT detection.
The copy of protective MBR is usually located in the
command, to restore the ability to detect the GPT.
The copy of the protective MBR is usually located in the

In case when some of metadata is corrupt you will get to know about this
from kernel's messages like these:
If one GPT header appears to be corrupt but the other copy remains intact,
the kernel will log the following:
.Bd -literal -offset indent

In case when the size of device has changed (e.g.\& volume expansion) the
secondary GPT header will become located not in the last sector.
If the size of the device has changed (e.g.\& volume expansion) the
secondary GPT header will no longer be located in the last sector.
This is not a metadata corruption, but it is dangerous because any
corruption of the primary GPT will lead to lost of partition table.
Kernel reports about this problem with message:
corruption of the primary GPT will lead to loss of partition table.
This problem is reported by the kernel with the message:

/*
* pcbgroups, or "connection groups" are based on Willman, Rixner, and Cox's
* 2006 USENIX paper, "An Evaluation of Network Stack Parallelization
* Strategies in Modern Operating Systems". This implementation differs
* significantly from that described in the paper, in that it attempts to
* introduce not just notions of affinity for connections and distribute work
* so as to reduce lock contention, but also align those notions with
* hardware work distribution strategies such as RSS. In this construction,
* connection groups supplement, rather than replace, existing reservation
* tables for protocol 4-tuples, offering CPU-affine lookup tables with
* minimal cache line migration and lock contention during steady state
* operation.
*
* Internet protocols, such as UDP and TCP, register to use connection groups
* by providing an ipi_hashfields value other than IPI_HASHFIELDS_NONE; this
* indicates to the connection group code whether a 2-tuple or 4-tuple is
* used as an argument to hashes that assign a connection to a particular
* group. This must be aligned with any hardware offloaded distribution
* model, such as RSS or similar approaches taken in embedded network boards.
* Wildcard sockets require special handling, as in Willman 2006, and are
* shared between connection groups -- while being protected by group-local
* locks. This means that connection establishment and teardown can be
* signficantly more expensive than without connection groups, but that
* steady-state processing can be significantly faster.
*
* Most of the implementation of connection groups is in this file; however,
* connection group lookup is implemented in in_pcb.c alongside reservation
* table lookups -- see in_pcblookup_group().
*
* TODO:
*
* Implement dynamic rebalancing of buckets with connection groups; when
* load is unevenly distributed, search for more optimal balancing on
* demand. This might require scaling up the number of connection groups
* by <<1.
*
* Provide an IP 2-tuple or 4-tuple netisr m2cpu handler based on connection
* groups for ip_input and ip6_input, allowing non-offloaded work
* distribution.
*
* Expose effective CPU affinity of connections to userspace using socket
* options.
*
* Investigate per-connection affinity overrides based on socket options; an
* option could be set, certainly resulting in work being distributed
* differently in software, and possibly propagated to supporting hardware
* with TCAMs or hardware hash tables. This might require connections to
* exist in more than one connection group at a time.
*
* Hook netisr thread reconfiguration events, and propagate those to RSS so
* that rebalancing can occur when the thread pool grows or shrinks.
*
* Expose per-pcbgroup statistics to userspace monitoring tools such as
* netstat, in order to allow better debugging and profiling.
