Updating on-disk metadata
|

-------------------------
|

|
||||
On-disk metadata is committed every time a REQ_SYNC or REQ_FUA bio is
|
||||
written. If no such requests are made then commits will occur every
|
||||
second. This means the cache behaves like a physical disk that has a
|
||||
write cache (the same is true of the thin-provisioning target). If
|
||||
power is lost you may lose some recent writes. The metadata should
|
||||
always be consistent in spite of any crash.

On-disk metadata is committed every time a FLUSH or FUA bio is written.

cache. If power is lost you may lose some recent writes. The metadata

The 'dirty' state for a cache block changes far too frequently for us

Updating on-disk metadata
|
||||
-------------------------
|
||||
|
||||
On-disk metadata is committed every time a FLUSH or FUA bio is written.
|
||||
If no such requests are made then commits will occur every second. This
|
||||
means the thin-provisioning target behaves like a physical disk that has

a volatile write cache. If power is lost you may lose some recent
|

writes. The metadata should always be consistent in spite of any crash.
|
||||
|
||||
If data space is exhausted the pool will either error or queue IO
|
||||
according to the configuration (see: error_if_no_space). If metadata
|
||||
space is exhausted or a metadata operation fails: the pool will error IO
|
||||
until the pool is taken offline and repair is performed to 1) fix any
|
||||
potential inconsistencies and 2) clear the flag that imposes repair.
|
||||
Once the pool's metadata device is repaired it may be resized, which
|
||||
will allow the pool to return to normal operation. Note that if a pool
|
||||
is flagged as needing repair, the pool's data and metadata devices
|
||||
cannot be resized until repair is performed. It should also be noted
|
||||
that when the pool's metadata space is exhausted the current metadata
|
||||
transaction is aborted. Given that the pool will cache IO whose
|
||||
completion may have already been acknowledged to upper IO layers
|
||||
(e.g. filesystem) it is strongly suggested that consistency checks
|
||||
(e.g. fsck) be performed on those layers when repair of the pool is
|
||||
required.
