123Updating on-disk metadata
124-------------------------
125
126On-disk metadata is committed every time a FLUSH or FUA bio is written.
127If no such requests are made then commits will occur every second. This
128means the thin-provisioning target behaves like a physical disk that has
129a volatile write cache. If power is lost you may lose some recent
130writes. The metadata should always be consistent in spite of any crash.
131
132If data space is exhausted the pool will either error or queue IO
133according to the configuration (see: error_if_no_space). If metadata
134space is exhausted or a metadata operation fails: the pool will error IO
135until the pool is taken offline and repair is performed to 1) fix any
136potential inconsistencies and 2) clear the flag that imposes repair.
137Once the pool's metadata device is repaired it may be resized, which
138will allow the pool to return to normal operation. Note that if a pool
139is flagged as needing repair, the pool's data and metadata devices
140cannot be resized until repair is performed. It should also be noted
141that when the pool's metadata space is exhausted the current metadata
142transaction is aborted. Given that the pool will cache IO whose
143completion may have already been acknowledged to upper IO layers
144(e.g. filesystem) it is strongly suggested that consistency checks
145(e.g. fsck) be performed on those layers when repair of the pool is
146required.

218 such sensors, expose the temperature information from these sensors
219 to userspace via the normal thermal framework. This means that a wide
220 range of applications and GUI widgets can show this information to
221 the user or use this information for making decisions. For example,
222 the Intel Thermal Daemon can use this information to allow the user
223 to select his laptop to run without turning on the fans.
