bdf and du

[j773303]

The bdf and du doesn't show the same available disk space. Any tools can sync the disk space, let it same both bdf and du. Thanks.

bdf is by bytes,du is by block(512bytes)

If your talking about the numbers, then use du -k which reports a 1024k block size.

If you think that the filesystem reports it's full, there is probably a file that has been removed that a process is holding it open.

sync will flush any recent changes:
# sync; sync; sync

Then you have to consider if a file was deleted but there might be a process that holds the file open. bdf counts these blocks as still allocated whereas du counts these blocks as free.

The way to make them match is to stop/restart the process that is holding the file open.
