comment Large, high performance object or key/value store for HTTP serving on Linux
It's a native ext3. And a relational database might not be that much more efficient, but a key/value store should be since it doesn't have to store metadata such as permissions, last updated etc. A deamon that carries a simple 64bit key with the image in the value field, should be small enough that all keys could be stored in memory. As such all lookups should be one IOP, given no fragmentation. Also note that having large amounts of files in one directory is limited by the readdir() call that only buffers 32K, and listing is thus very slow.

comment Large, high performance object or key/value store for HTTP serving on Linux
Thanks for your input. I know that a nosql database won't solve all my problems (probably), but if it can store objects more efficiently with less metadata/overhead (with for instance a 64bit key) it would solve some of my seek issues. Looking up a file in a large directory structure generates a lot of IOPS and thus a delay. I was hoping an in memory index could solve the seek issue and result in a single IOP for each object.

comment How can I shrink an LVM partition on CentOS?
vgresize is not something I'm familiar with. Could it be vgreduce ? But even that only manages the number of LVs in a VG.
