>Description: Growfs has a 32bit integer internall, where it should have a 64bit. This has the effect that filesystems over a certain size cant be enlarged. >How-To-Repeat: Try to enlarge a filesystem whos size is beyond 2^32 >Fix: Hi Growfs team I believe i have uncovered a bug in growfs related to 32bit integers. My original enquirey to freebsd...@freebsd is archived at ... http://marc.info/?l=freebsd-fs&m=128533133814268 You can see that i have enlarged a disk where i had previous formatted it without slices/partitions. I then wanted to grow the filesystem to match. I dont believer there is a problem with the slices/noslices side of things, but i believe there is an integer looping inside growfs which is causing it to refuse to enlarge. I poked around in the source code and i believe that the p_size variable should be 64bit. Some googling shows support for this theory... here is another person reporting the same problem as myself first post - http://fixunix.com/freebsd/293354-growfs-filesystem-size-limits.html discussion about p_size - http://fixunix.com/freebsd/293353-re-growfs-filesystem-size-limits.html further discussion - http://fixunix.com/freebsd/293364-re-growfs-filesystem-size-limits.html here is a much more recent thread with the same sort of problem http://forums.freebsd.org/showthread.php?t=15252 which includes a link to patch for an older version of growfs http://masq.tychl.net/growfs.patch Which expands upon the changes outlined in the 'fixunix.com' discussion. I am hoping that you can make appropriate changes in growfs and release them in to freebsd. Thank you for your good work.
