Subject: directory defrag
Date: Tue, 14 Apr 2015 07:37:17 +0000 [thread overview]
Message-ID: <201504140737.17826.russell@coker.com.au> (raw)
The current defragmentation options seem to only support defragmenting named
files/directories or a recursive defragmentation of files and directories.
I'd like to recursively defragment directories. One of my systems has a large
number of large files, the files are write-once and read performance is good
enough. However performance of "ls -al" is often very poor, presumably due to
metadata fragmentation.
The other thing I'd still like is the ability to force all metadata allocation
to be from specified disks. I'd like to have a pair of SSDs for RAID-1 storage
of metadata and a set of hard drives for RAID-1 storage of data.
