Revision as of 02:34, 10 December 2012

Hardware

  • SuperMicro SC742 4U server case
  • SuperMicro X9SRA motherboard
  • Intel Xeon E5-2650 Sandy Bridge-EP 2.0GHz (2.8GHz Turbo Boost) LGA 2011 95W 8-Core Server Processor
  • SUPERMICRO SNK-P0050AP4 Heatsink for Supermicro X9DR3-F Motherboard
  • 32GB ECC registered RAM (4 x 8GB)
  • Four 15K 150GB drives HITACHI HUS153014VL
  • Corsair Neutron Series GTX CSSD-N240GBGTX-BK 2.5" 240GB SATA III Internal Solid State Drive (SSD)
  • 3Ware 9690SA-4I SATA/SAS RAID controller

Drive Config

I ended up doing the entire config using the CentOS installer, but left this information here because going through the steps myself helped me understand how LVM works. I created some virtual drives and played around with them in a VirtualBox installation of CentOS to work in a safe environment where I would not be able to break anything.

Hardware

sda 3Ware 435 (4 x Hitachi 150GB in RAID 5)
sdb Neutron SSD 240
sdc Neutron SSD 240
sdd WDC Black 1000
sde Revo 60
sdf Revo 60

2 x Neutrons => partitioned for boot and md0 RAID 1 = operating system
2 x Revos => md1 RAID 0 = fast workspace
3ware RAID => /var and other fast data storage
Black = home, bulky data, swap

Volume groups 

vg_mirror
vg_workspace
vg_raid
vg_bulk

Logical volumes 

lv_root      /
lv_workspace /workspace
lv_var       /var
lv_home      /home
lv_swap      SWAP

Neutron drive: Build a broken mirror, add second drive later

[See http://www.gagme.com/greg/linux/raid-lvm.php Managing RAID and LVM with Linux] For install onto RAID see also some of the steps here Install on partitionable RAID1

Here are the commands that I used. 

# Use the entire drive and put the partitions inside /dev/md_d0
mdadm --create --metadata=0.90 --level=mirror --raid-devices=2 /dev/md_d0 /dev/sda missing
# put RAID1 into LVM2
pvcreate /dev/md0
vgcreate vg_mirror /dev/md0

# later, set up second drive as the mirror
mdadm --add --verbose /dev/md0 /dev/sdb2
# the mirror should automatically be added to LVM since it's part of /dev/md0
cat /proc/mdstat

Revo drive: completely managed under LVM2

The Revo drive has its own RAID onboard. I set up the two halves as RAID 0 for performance at the cost of potential dataloss. The drive is visible to Linux as /dev/sde and /dev/sdf and also as a RAID at /dev/mapper/sil_bibibgajfbdj (a name only its mother could love.) I set it up under LVM2 thusly

[root@dart ~]# pvcreate -v /dev/mapper/sil_bibibgajfbdj 

   Set up physical volume for "/dev/mapper/sil_bibibgajfbdj" with 234458624 available sectors
   Zeroing start of device /dev/mapper/sil_bibibgajfbdj
 Writing physical volume data to disk "/dev/mapper/sil_bibibgajfbdj"
 Physical volume "/dev/mapper/sil_bibibgajfbdj" successfully created

[root@dart ~]# vgcreate --verbose vg_workspace /dev/mapper/sil_bibibgajfbdj 

   Wiping cache of LVM-capable devices
   Adding physical volume '/dev/mapper/sil_bibibgajfbdj' to volume group 'vg_workspace'
   Archiving volume group "vg_workspace" metadata (seqno 0).
   Creating volume group backup "/etc/lvm/backup/vg_workspace" (seqno 1).
 Volume group "vg_workspace" successfully created

[root@dart ~]# lvcreate --verbose --extents 100%FREE -n lv_workspace vg_workspace 

   Setting logging type to disk
   Finding volume group "vg_workspace"
   Archiving volume group "vg_workspace" metadata (seqno 1).
   Creating logical volume lv_workspace
   Creating volume group backup "/etc/lvm/backup/vg_workspace" (seqno 2).
   Found volume group "vg_workspace"
   activation/volume_list configuration setting not defined: Checking only host tags for vg_workspace/lv_workspace
   Creating vg_workspace-lv_workspace
   Loading vg_workspace-lv_workspace table (253:5)
   Resuming vg_workspace-lv_workspace (253:5)
   Clearing start of logical volume "lv_workspace"
   Creating volume group backup "/etc/lvm/backup/vg_workspace" (seqno 2).
 Logical volume "lv_workspace" created

[root@dart ~]# mkfs.ext4 /dev/vg_workspace/lv_workspace

/dev/vg_workspace/lv_workspace will be mounted at /workspace

3Ware RAID5: completely managed under LVM2

pvcreate /dev/sd?
vgcreate vg_raid /dev/sd?
lvcreate -l ????? vg_raid -n lv_var
mkfs.ext4 /dev/vg_raid/lv_var

After installing OS, /dev/vg_raid/lvm0 will be mounted at /var

Black drive: completely managed under LVM2

Might also want some SWAP on here? 

parted set up one LVM partitions
mark partition type as 8e = LVM
pvcreate /dev/sdd
vgcreate vg_bulk /dev/sdd
lvcreate -l ????? vg_bulk -n lv_home
lvcreate -l ????? vg_bulk -n lv_swap
mkfs.ext4 /dev/vg_bulk/lv_home
mkswap /dev/vg_bulk/lv_swap

Will be mounted as /home and swap

Commands to view what we've done

This is how things actually look right now. I have not worked on the Revo drives yet.
