Yet another thing, someone has suggested that I should increase the chunk size for my RAID5 from 32 to either 64 or 128. Is it worth it, considering that the system doesn't normally run on a heavy load? Mail for a few users, some read-only database applications, website, etc. Mostly a development machine.
Can't think of a case where it's not worth having better performance... I should write a WP on stripe size, and what happens as you change it with given loads.
Would this alleviate the "pauses" during large file transfers/copies that I have indicated in my previous post? I'm asking because backing up ~176 GB, reconfiguring the RAID, and restoring it properly so the machine boots (the RAID5 is /) is quite a PITA.
You may have some special case, but I would never put data that large in / just as a system admin issue. It makes backups and restores, as well as upgrades quite unpleasant. I guess you may have noticed that by now ;-) Good luck!
