Abstract
Rather than unmounting a corrupt filesystem while doing recovery, the filesystem remains mounted but I/Os to the corrupt area are blocked while a repair process is called to repair the corruption. Threads attempting to access the filesystem go into a waiting state until the corruption is fixed, then are restarted at a stable point in their execution.
Claims13
A computer system, comprising:
- a first processor connected as a server;
- a plurality of client processors connected to communicate with said first processor;
- a filesystem connected to be accessed from said first processor and said plurality of client processors;
- and
- a set of instructions configured to run on said computer system, wherein when a first portion of said filesystem is found to be corrupt, said set of instructions are connected to:
- receive information regarding a location of said first portion and a perceived corruption, isolate said first portion of said filesystem while leaving other portions of said filesystem available, and
- provide repair for said filesystem.
4 more elements
A method of operating a computer system, comprising the steps of:
- receiving information regarding a first portion of a filesystem and a detected corruption in said first portion of said filesystem;
- isolating said first portion of said filesystem while leaving other portions of said filesystem available, and
- providing for a repair of said first portion of said filesystem.
A computer program product on a computer readable medium, said computer program product comprising:
- first instructions for receive information regarding (a) a first portion of a filesystem, and (b) a detected corruption within said first portion of said filesystem;
- second instructions for isolating said first portion of said filesystem while leaving other portions of said filesystem available, and
- third instructions for providing repair for said filesystem.
