Cross-file-system version on-line upgrading method and device

Abstract

The invention discloses a cross-file-system version on-line upgrading method and device. The method comprises the following steps: downloading a main version file to be operated from the current version system; starting a system guidance program to obtain the current file system type in a flash memory, and initializing the current file system; obtaining main version information and the file system type of the main version; judging whether the main version can be operated on the current file system or not, generating a result according to judgment, and causing the current file system to operate the main version. According to the on-line upgrading method disclosed by the invention, the version capable of operating different file systems can be supported to be upgraded on line, the version upgrading process is totally automatically recognized, the difference of the operation steps of upgrading and rolling back the version due to different file systems is not brought for the user, manual operation is reduced, and the upgrading efficiency and the use satisfaction degree of the user can be improved. The method disclosed by the invention is also suitable for upgrading the versions of the main system and backup system as well as the version of a line card.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for online upgrading of versions across file systems. Background technique [0002] Version upgrade is the most common operation in communication products. In order to meet new functions or new requirements, the product version needs to be upgraded, and there may be cross-platform or cross-file system version upgrades. For example, the original system uses the vxWorks operating system. In order to support some new functions, it needs to be replaced with a linux operating system; another example, due to the relationship between the adopted platform, the old and new versions of the file system may be different. To upgrade the software version of these systems, it is necessary to ensure that all hardware remains unchanged: all data in the version and file system before and after the upgrade will not be lost; the upgrade operation is simple and convenient,...

Problems solved by technology

However, the disadvantage of this method is that the new main version cannot be directly upgraded in the old version, and the main version must be upgraded in the new boot software, which is complicated to operate and cannot satisfy online upgrades; due to the incompatibility of the old and new file systems , the data cannot be saved, and the data needs to be backed up to other servers in advance, and the data can only be restored after the new main version runs. The operation is complicated and it is difficult to satisfy batch operations; got the same problem

The disadvantage of this method is: due to the consistency of the reserved data address in the old version and the data address obtained in the new boot software, it is necessary to customize the old version and the new boot software, that is, the old version Upgrade to a temporary version first, and then upgrade to a new version; also if the new version needs to roll back to the old version, the old boot software also needs to be modified
