Misaligned partition on replacement drive in RAID 5 array, Fedora 14


I have a RAID array of 4 2TB drives running Fedora 14.

A while ago, one of the drives died and I replaced it with a new one. The array repaired itself and everything seemed fine.

However, I noticed in palimpsest that it displays the message:

WARNING: The partition is misaligned by 3072 bytes. The may result in very poor performance.

I came across this exact problem before a few years ago and somehow managed to solve it, but this time around, I can't remember what I did or where on the net I found the answers.

How do I go about fixing this and then re-adding it to the array without risking screwing things up and damaging the FS on the array (very important research data without another backup and not enough space anywhere else to put the 3.5TB on it).?

Ignore it. Take the (potential) performance hit.

Modern tools (fdisk, parted, whatever) would aoutomagically allow for this on allocation of the partition. F14 isn't modern (hint ....)

Could you tell me how to test the read/write on this RAID to find out how bad the performance hit is?

Is it easy to upgrade my fedora?

NO or yes , depending on how you define "easy"

The current fedora 18 ( soon to be 19 ) is VERY VERY different than fedora 14

there is no real way to upgrade

You need to do a new clean install of Fedora 18
also so many things have changed ( like the default database ,it is now "mariaDB" and not MySQL )
firefox is now ff 21

the nividia driver ( if you have a nvidia card) uses the nouveau kernel mod by default

that most of the config files and database files in your home folder will not port to the new fedora
you will need to manually reinput most of the data

then see the fedora 15 & 16 & 17 & 18 change logs

Thanks.

Also, rather inane question, but, I have Fedora 17 I think on another computer....and it has that new desktop layout. Can I switch the newest versions to the old gnome desktop or am I stuck with that new one?

gnome2 dose not run on the current fedora

CentOS 6.4 or ScientificLinux 6.4 are using Gnome 2 and has about 5 years of support left
