It started out as "this'll be just a simple fix ..." and turned into something a bit over-engineered in the end. Here it is anyway. Rich.

v2 -> v3: - Drop gnulib fallback.

v1 -> v2: - Removed the f_type field from StatVFS.statvfs structure. - New function StatVFS.filesystem_is_remote, written in C. [Thinking about it, this should probably be called ?is_network_filesystem?, but I can change that before pushing]. - Use statvfs instead of fstatvfs, and statfs instead of fstatfs. - Rejigged the comments in builder/builder.ml to make them simpler

We are having problems remounting an ext3 filesystem using an external journal device. The filesystem in question was working fine until the server was rebooted. This is what we see on dmesg when trying to mount: EXT3: failed to claim external journal device. The external journal lives on a LVM2 logical volume and it seems to be accessible ( we can dumpe2fs and see filesystem information).

...eturn different >values. I''m not sure I even require this much. As long as rescale_frsize() doesn''t drop non-zero bits in the values it shifts to the right, I think I''m OK with statvfs() and statvfs64() returning different values for f_frsize, f_blocks, f_bfree, and f_bavail as long as the values f_frsize*f_blocks, f_frsize*f_bfree, and f_frsize*f_bavail are the same (using types for the multiplication that don''t overflow) in both calls. If statvfs() returns EOVERFLOW if the values returned would be different from those returned by statvfs64(), I''ll...

Hello, I just noticed that 'tune2fs -l' did not returned a "lively" updated information regarding the free inodes count (looks like it's always correct after unmounting). It became suprising after an online resizing operation, where the total inode count was immediatly updated (grown in my case) but the free inode count was the same: one could deduce that suddenly a lot of
