> > ******************************************************************************************************* > UPDATE 24 May 2016 > > 3x WDC WD30EFRX ATA 3Tb disks added to aidas1 LVM configuration - see https://elog.ph.ed.ac.uk/AIDA/233 > ******************************************************************************************************* > > Reminder > > The additional 3x 3Tb disks (and the USB 8Tb disk currently attached to > aidas1) are not included in the aidas1 /etc/fstab file and do *not* have > fixed device names, i.e. the device name of each disk can change at each > reboot. > > The Fix > > To avoid this problem for the 3x 3Tb disks Vic suggests converting them > from ext4 format to lvm format and 'appending' each disk volume to /data10 > (which is already lvm). This will require re-formatting disks /data20, 30 > & 40. Backups (and checks) have now been performed for /data20, 30 & 40. > I will re-format these disks upon my return to RIKEN May 22. > > The Workaround > > Mount the disks manually as superuser. > > How to work out which device is associated with which disk? > > From SL6 window header select Applications -> System Tools -> Disk Utility > > N.B. BE VERY CAREFUL USING THIS TOOL! > > In the Disk Utility window a list of storage devices will be shown on the > left hand side - you will be interested in the 3x 2.2Tb Hard Disks attached > to the SAS Host Adaptor *and* the USB 8.0Tb Hard Disk attached to peripheral > devices. > > Select the required device - drive and volumes information will appear on > the right hand side of the Disk Utility window - check the disk label and > device shown in the volumes section. > > For example - if the selected device volume information is label 'data20' > and device '/dev/sdf1' you can mount the disk as superuser with the command > > mount -t ext4 /dev/sdf1 /data20 > > To mount the USB disk (having obtained the device name as above) you can > mount the disk as superuser with, for example, the command > > mount -t ntfs-3g /dev/sda2 /ntfs
