#!:Disk Performance Test:

[root@ngasdev1 NGAS]# /sbin/hdparm -t /dev/sda1

/dev/sda1:
 Timing buffered disk reads:  64 MB in  1.25 seconds = 51.20 MB/sec
[root@ngasdev1 NGAS]# 
----------------------------------------------------------------------------
#!:Disk Test:
Non-destructive read-write test (produced list of bad blocks):

badblocks -nvs <device>

Destuctive test (__'s inserted to ensure that the wrong command is
not cut and pasted):

__bad__blocks__ __-svw__ <device>

Latter writes patterns on the disk while checking so that all data on 
the disk is lost.

#!:Export Release to SOS:
sftp (or scp) your software to ngas@aclxint:/home/ngas/ngas_software/

this is then automatically rsynced to

#!:Prepare disks (reiserfs, fdisk)
1.) you have to be root
2.) > fdisk /dev/sd*            # * has to be replaced by the actual
letter, e.g. /dev/sda
3.) fdisk is an interactive tool:
     In fdisk you have to create a new primary partition covering the
whole disk, i.e. just use the defaults when it askks for the first and
last blocks
     use the command w to write the partition definition to the disk
and quit fdisk
4.) > mkreiserfs /dev/sd*1    # again the * has to be replaced by the
letter (note the number!)
5.) > mount -t reiserfs /dev/sd*1 /NGAS/data1
6.) > chown ngas:ngas /NGAS/data1
7.) > chmod g+wx /NGAS/data1

8.) go back to 2.) for any further disk
----------------------------------------------------------------------------
#!:Ramdisk/Filedisk:
Can be used to create a filesystem in a file (in this case ext3fs):

Create a file system of the desired size and copy it to a file using dd:

# /sbin/sfdisk /dev/sda
# /sbin/mke2fs -j /dev/sda1
# dd if=/dev/sda1 of=/tmp/100kB_ext3fs bs=1024 count=96389
# mount -o loop /tmp/100kB_ext3fs /mnt/filedisk
----------------------------------------------------------------------------
#!:RedHat Network Configuration:
The following files should be adjusted to each NGAS  system:

	/etc/hosts
	/etc/sysconfig/network
	/etc/sysconfig/network-scripts/ifcfg-eth0

#!:Zope:
