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).

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.

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
