| - | On budlight, we have recently (May 2009) added a Clariion DAE (http://support.dell.com/support/edocs/stor-sys/dae/fcdae/fchardwr.pdf). The enclosure has an EMC label on it, but the documentation we have is for the same device rebranded and resold through Dell. We have it connected to budlight via a QLogic ql2100 HBA. The Clariion has 10 bays, each with a 36G FCAL drive. | ||
| - | |||
| - | To make budlight see the drives in the DAE, we needed to install the qlogic-firmware package. | ||
| - | |||
| - | <code root> | ||
| - | # apt-get install firmware-qlogic | ||
| - | </code> | ||
| - | |||
| - | After a reboot, budlight saw /dev/sd[a-j] | ||
| - | |||
| - | We have assembled the drives into a RAID-5 array with one hot spare. This should give us roughly 300G, which is a huge increase in available storage. | ||
| - | |||
| - | The assembly command is: | ||
| - | |||
| - | <code root> | ||
| - | # mdadm --create /dev/md0 --level=5 --raid-devices=9 --spare-devices=1 /dev/sd[a-j]1 | ||
| - | </code> | ||
| - | |||
| - | /proc/mdstat will show the progress of building the array. This is what it looks like when it is fully built: | ||
| - | |||
| - | <code root> | ||
| - | Personalities : [raid6] [raid5] [raid4] | ||
| - | md0 : active raid5 sdi1[8] sdj1[9](S) sdh1[7] sdg1[6] sdf1[5] sde1[4] sdd1[3] sdc1[2] sdb1[1] sda1[0] | ||
| - | 279302144 blocks level 5, 64k chunk, algorithm 2 [9/9] [UUUUUUUUU] | ||
| - | |||
| - | unused devices: <none> | ||
| - | |||
| - | </code> | ||
| - | |||
| - | After /proc/mdstat shows that md0 is fully assembled, we'll update mdadm.conf: | ||
| - | |||
| - | <code root> | ||
| - | # mdadm --detail --scan >> /etc/mdadm/mdadm.conf | ||
| - | </code> | ||
| - | |||
| - | In order to gain flexibility with the EMC DAE, we will need to install some additional packages: | ||
| - | |||
| - | <code root> | ||
| - | # apt-get install lvm2 dmsetup | ||
| - | </code> | ||
| - | |||
| - | This will allow us to create LVMs which can be resized as needed out of the logical RAID-5 device on the Clariion. | ||
| - | |||
| - | Label /dev/md0 as a physical volume: | ||
| - | |||
| - | <code root> | ||
| - | # pvcreate /dev/md0 | ||
| - | </code> | ||
| - | |||
| - | Create the volume group: | ||
| - | |||
| - | <code root> | ||
| - | # vgcreate sluug /dev/md0 | ||
| - | </code> | ||
| - | |||
| - | Create a 40G logical volume in the sluug VG called 'rsnapshot': | ||
| - | |||
| - | <code root> | ||
| - | # lvcreate -L 100G -n rsnapshot sluug | ||
| - | </code> | ||
| - | |||
| - | Format the rsnapshot volume and mount it: | ||
| - | |||
| - | <code root> | ||
| - | # mke2fs -j /dev/mapper/sluug-rsnapshot | ||
| - | # mkdir /rsnapshot | ||
| - | # mount /dev/mapper/sluug-rsnapshot /rsnapshot | ||
| - | </code> | ||
| - | |||
| - | Revel in the newly available space: | ||
| - | |||
| - | <code root> | ||
| - | df -h /dev/mapper/sluug-rsnapshot | ||
| - | Filesystem Size Used Avail Use% Mounted on | ||
| - | /dev/mapper/sluug-rsnapshot | ||
| - | 40G 177M 38G 1% /rsnapshot | ||
| - | </code> | ||
| - | |||
| - | And add the following to /etc/fstab: | ||
| - | |||
| - | <code root> | ||
| - | /dev/mapper/sluug-rsnapshot /rsnapshot ext3 defaults 0 0 | ||
| - | </code> | ||
