Better than POSIX?Better than POSIX?Posted Mar 19, 2009 18:33 UTC (Thu) by anton (guest, #25547)In reply to: Better than POSIX? by dlang Parent article: Better than POSIX?
no, currently there is no API in existance for any filesystem (including ext3) that will _guarantee_ that you have either the old or the new filesystem on disk after a crash with no possibility of garbage (even excluding things that damage the drives themselves)I am pretty sure that there are file systems around that give such guarantees. This was certainly one of the goals of LinLogFS and LLFS; ok, these filesystems have not come out of the development stage (yet), but I would be surprised if there were no others (ZFS?). Concerning an API, I don't see a need for an additional API, it's just a matter of whether the file system gives consistency guarantees in case of a crash when using the existing file API, and if so, which ones.
