--- Comment #12 from Theodore Tso ---
Hi Louis,
Can you talk a bit about your workload? What sort of applications are you
running on the file system which is having the problems? A database? Squid
cache, something else? Is it a lot of random writes? What sort of files
does it create? Does it create and delete a lot of files? Etc.
It looks like your system has 8GB of memory --- is that right? How much free
memory does your machine normally has? Also, if you still have your ext4 file
system image, could you run "e2freefrag -v /dev/mapper/XXX"?
Many thanks!!
