The 3x WDC WD30EFRX ATA 3Tb disks installed in aidas1 in April 2015 (formerly /data20, /data30 and
/data40) have now been added to the aidas1 logical volume management (LVM) configuration to form a
single c. 8Tb filesystem (/data10) which will be automatically mounted at boot.

N.B. Although the disks are 3Tb capacity, Linux OS/BIOS can only access the first 2.2Tb of each disk.

Data previously stored on /data20, /data30 and /data40 has been copied to the local Seagate USB 8Tb
disk (/ntfs) and the University of Edinburgh ECDF multi-Pb disk array.
