Even if you put more in it, the 32-bit address space limit will be the limiting factor. > What should I do and how to check my volume? You almost certainly need a 64-bit machine. Even with the latest xfs_repair, you need about 2GB of RAM for the free space checking on a 14TB filesystem. Try running: # xfs_repair -m 1 -vv And it will tell you how much memory you need to repair the filesystem. Note that this is only a rough estimate - it may be quite a bit more than the amount specified depending on the state and contents of the filesystem...
