rpcbut lvm isn't reliable i hear :)
Wyzardbut you should be aware of the risks of striping, both with LVM and with RAID-0
houndIt can't find a certain device, I think i'll have to reboot into the system to figure out what it's doing. I should only have two physical volumes (which it finds).
WyzardLVM isn't *unreliable*
kramedhow do you resize a lvm ?
boot cd?
rpcWyzard hm yes.. striping will kill my data completely if one of those drives fail...
WyzardProtecting against disk failure is just not something it's intended to do
maddashrpc: LVM has nothing to do with reliability, just flexibilitiy
s/flexibilitiy/flexibility
Wyzardkramed: lvextend, lvreduce
rpcmaddash i read you and i think i will quit the lvm plan
Wyzardrpc: right -- and that's true regardless of whether you use RAID-0 or LVM
rpci will quit raid plan as well :)
maddashrpc: erm, LVM in and of itself, I meant
houndof course it depends on your file system how you can resize too.
Wyzardrpc: That's why on my system I use RAID-5 with three drives for reliability, and on top of that, LVM for flexibility
rpchm sounds really good, just lvm on top of that, and not as the basic thing
maddashWyzard: is that software or hardware RAID? what're your access speeds?
Wyzardrpc: On my laptop, which only has one hard drive, I just use LVM; that's no more of a risk than using ordinary partitions on that single drive
rpcand i want r5 too.. until that happens i will stay with 2xsata setup..
Wyzard hm lvm instead of partitioning?
kramedlvms have to be unmounted to resize?
Wyzardmaddash: software... hdparm tells me it reads 125.87MB/sec from /dev/md0, but it's writing where RAID-5 takes its performance hit, not reading
rpc: Well, I have a /boot partition since that needs to be a plain partition, and a swap partition because I use a different encryption scheme for that
rpc: and then a single big partition which contains the LVM volumes
maddashyou know what would be the perfect server? Xen+LVM+RAID5+LUKS.
BUMBACL0Trpc, why is it saying this: 500 OOPS: vsftpd: cannot locate user specified in 'ftp_username':ftp
Wyzardrpc: That's on my laptop with just one hard drive
rpc: On my desktop with three identical drives, I have first a 50MB /boot partition on one of the drives (and empty space on the other two), a trio of 1GB partitions which form a RAID-0 stripe set for my swap, and the rest of the space is a trio of big partitions which are my RAID-5 array for all my data
rpc: but in both cases there's a big block device (either plain partition or RAID array) which is divided up into multiple filesystems with LVM
rpchm.
Wyzardmaddash: I thought about using whole-disk crypto on my Xen router/firewall/fileserver, but decided it wasn't worth it, and it's headless so it'd suck to have to type a passphrase if it gets rebooted
maddashWyzard: er, use a keyfile
Wyzardrpc: and in both cases that big block device (partition or RAID) is encrypted
maddash: For whole-disk encryption the initrd would have to read the keyfile, and I don't think it supports that
zoidymaddash: thanks again, privoxy is exactly what I was looking for
maddashzoidy: great.
houndi put my keyfile inside the initrd because I was sick of typing in a password.
maddashWyzard: there are docs out there documenting procedures to do just that. even crypttab has a field that denotes the keyfile location.
