}Hum, maybe there's a problem here too.
}The fact that the total size changes is normal; there's no fixed space for
}metadata in LFS, so the free space available for data blocks depends on
}the space used for the metadata (so, from the number of files). When the
}filesystem is idle, the cleaner can eventually garbage-collect metadata and
}free some space.
Currently:
lyra:/stuff# df -k .
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/raid0d 54912677 7583326 46780225 13% /stuff
lyra:/stuff# du -sk .
2392785 .
lyra:/stuff# du -a|wc -l
115295
The space used seems excessive for what's there.
lfs_cleanerd wasn't running most of today, as the window I was running
it in in debug mode died, and I was gone. So garbage collection has
only been running for about 2 hours total since my earlier message.
