Re: [HELP] RAID chunk-size
chunk size does NOT matter for raid5...
if your disk was partitioned as... 2K bytes/inode...
chunksize of 32 will allow you to write 64K of data
in one "chunk" to disks
chunksize of 128 will allow you to write 256K of data
in one "chunk" to disks...
or so goes the idea...
whether your disks can sustain that or not is another issue
it also makes a difference if you used a inode size of 1K or 2K or 4k
during disk partitioning
- lots of little files or few huge/gigantic files ??
