Summary	0000267: make blocksize a property of the pool
Description	As it is not possible to easily switch the block size of a tape after it was written, but the blocksize has big impact on tape speed, it would be nice to be able to use different blocksizes in different pools in order to be able to do a migration to another blocksize. For more info, see the tape speed tuning whitepaper: http://www.bareos.org/en/Whitepapers/articles/Speed_Tuning_of_Tape_Drives.html

joergs 2015-03-25 19:19 developer ~0001625	Due to the reimport of the Github repository to bugs.bareos.org, the status of some tickets have been changed. These tickets will be closed again. Sorry for the noise.

bareos: master 860aaeb1 2014-02-25 10:19 pstorz Committer: mvwieringen Ported: N/A Details Diff	Adds support for different blocksizes. Min- and maxblocksize are now a property of the pool and are promoted to tapes in that pool. Therefore, the media and pool database tables were adapted to hold min and maxblocksize. In order to be able to read the tape label always, the label is always read and written with the DEFAULT_BLOCK_SIZE = 63k/64512 bytes For backward compatibility, the blocksize DEFAULT_BLOCK_SIZE is used if the blocksize for the medium is zero in the database table. The device blocksizes are set to the values of the mounted volume after it was mounted, so all blocks being written after the label block are written with the blocksizes configured in the medium/pool. Moving a tape from one pool to another through the scratch pool mechanism is supported, as then the pool's properties are promoted to the medium. This new feature makes it possible to move from one blocksize to a new one during normal operation while being able to restore the old backups at any time. For disaster recovery (DR) using bscan etc. you need to set the blocksize used during write of the tape for restore. Fixes 0000267: make blocksize a property of the pool	Affected Issues 0000267
