Doc Type: Bug Fix
Doc Text:
Some of the functions in the GFS2 file system were not reserving enough space for the resource group header in a transaction and for resource groups bit blocks that get added when a memory allocation is performed. That resulted in failed write and allocation operations. With this update, GFS2 makes sure to reserve space in the described scenario, using the new gfs2_rg_blocks() inline function.
