Each diskless box can mount local disk partitions to use them as temporary repository of the running OS. This allows to increase performance and reduce the network load of the nfs mounted partitions.
The partitions defined on local HD are:
- swap partitions
- tmp partition
Each box should initialize the local disk according to a a pre-built configuration of the partition schema:
On each diskless node:
cat /var/local/hda.out
gives:
# partition table of /dev/hda unit: sectors /dev/hda1 : start= 63, size= 3919797, Id=82 /dev/hda2 : start= 3919860, size= 3919860, Id=82 /dev/hda3 : start= 7839720, size=148456665, Id= 5 /dev/hda4 : start= 0, size= 0, Id= 0 /dev/hda5 : start= 7839783, size= 9783522, Id=83
This file is used to initialize the local disk as follows:
sfdisk -f /dev/hda < /var/local/hda.out mkswap -L swap1 /dev/hda1; mkswap -L swap2 /dev/hda2; mkfs -t ext3 /dev/hda5; e2label /dev/hda5 /tmp;
Once the partitions are built, mount them:
swapon /dev/hda1; swapon /dev/hda2; mount /tmp
