Abstract
In a reliable distributed computing system, techniques where user actions or events affecting real system devices (RSD's), or causing the system to make changes to metadata, require fewer accesses to RSD's. When a virtual system device (VSD) is mounted, substantially all the metadata, or at least that associated with data recovery, is read into memory. Changes to that metadata can be made substantially without any metadata accesses to RSD's. No metadata accesses to RSD's are made for read operations, as the RSD would remain unchanged. Metadata is flushed from memory upon write operations. Metadata about data locations can be maintained in memory, so as to be available if any RSD becomes corrupted or otherwise comes to lose data.
