Well, for what it's worth, xfs doesn't use MAX_LFS_FILESIZE for s_maxbytes, and: # mkfs.xfs -dfile,name=fsfile,size=5g ... # mount -o loop fsfile mnt/ # cd mnt/ # truncate --size 17592186044415 bigfile # ls -lh bigfile -rw-r--r--. 1 root root 16T Mar 29 14:03 bigfile # uname -m i686 it is possible to create a > 8T file offset. Now, whether the vm is really happy with this probably remains to be seen; this is the sort of thing that breaks without constant testing, IMHO. I'd certainly suggest that a 64-bit box is the best way to go if at all possible. -Eric _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
