Is there a filesystem that can fragment a large, existing file to perform arbitrary inserts?
- tyingq 10y agoCommon in the mainframe world, like VSAM. That would be variable length record oriented files, versus stream files. Someone did do this for GEOS: http://justsolve.archiveteam.org/wiki/GEOS_VLIR http://justsolve.archiveteam.org/wiki/GEOS_VLIR , but I've never seen that for anything remotely unix like.
- duskwuff 10y agoUnlikely. It's difficult to implement, and can be worked around by applications that need it.
- koverstreet 10y agofallocate(FL_INSERT_RANGE) can do that, but only on block boundaries
