Man, there is nothing cooler than this:
vgextend mediavol /dev/hdc1
lvextend -l +59618 /dev/mediavol/media
The downtime was just long enough to put the drive in. +250G to argus 8)
oh man... RAID... :D
I need a few hotswap bays to really make that happy...
Remind me, are you using hardware or software raid?
(also, replace hdc with sdc and it IS cooler! sata is so rad! and I'm pretty sure it's hotswappable.)
In this case, it's not actually RAID, it's LVM. That's all software, of course. I'm not using striping for performance reasons.
On b, I use both RAID and LVM. In that case, the RAID is hardware using a Mylex DAC960.
PATA can be hot swappable as well, but it's not a big deal. Did I mention that I put the drive in a few nights ago and ran those commands from ~50 miles away?
striping would be detrimental to the overall performance? howzat?
i really need to look in to LVM. looks interesting.
striping on top of a RAID would just be silly, really.
I haven't confirmed this, but I've heard people complain that the striping is slow on LVM.
It's really easy to look into -- just grab the HOWTO from tldp.org. It's pretty well written. All you really need to understand is the relationship between volume groups, logical volumes, and physical volumes. Once you grok that, you can just use their cookbook portion.
I need more hard drives now :D
You do. You giant multicolored facial hair sissy!
thats Mr Multicolored Facial Hair Sissy to you...

This is mounting a total of 7 remote drives using AOE - thanks again for the point-out on this one.
