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.

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

v2 -> v3: - Drop gnulib fallback.

...rd requiring "X free - not X+1" is, hmm, >to say it politically correct, "difficult to meet with a filesystem that >does compress/tail-compact". The point I was complaining about with "X free - not X+1" was that the suggested changes cap the values returned in f_files, f_ffree, and f_favail at UINT32_MAX. If a 32-bit statvfs() returns UINT32_MAX for any of these values when a simultaneous 64-bit statvfs() or a statvfs64() would set one or more of those values to a larger value (I don''t care if it is +1, *2, or *1000), I think we have a problem. >T...

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).
