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. aidas1> df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_aidas1-lv_root 50G 27G 20G 58% / tmpfs 3.9G 1.1M 3.9G 1% /dev/shm /dev/sdb1 477M 77M 376M 17% /boot /dev/mapper/vg_aidas1-lv_home 860G 106M 816G 1% /home /dev/mapper/Data1-data10 7.7T 1.6T 5.8T 22% /data10 /dev/sda2 7.3T 3.4T 4.0T 46% /ntfs [root@aidas1 /]# ln -s /data10/TapeData /TapeData [root@aidas1 /]# ls -l / total 210 dr-xr-xr-x. 2 root root 4096 Apr 7 03:49 bin dr-xr-xr-x. 5 root root 1024 Feb 17 2015 boot drwxr-xr-x. 10 root root 4096 Jul 23 2015 cgroup drwxr-xr-x. 8 root root 4096 Dec 12 19:29 data10 drwxr-xr-x. 2 root root 4096 Apr 28 2015 data20 drwxr-xr-x. 2 root root 4096 Apr 28 2015 data30 drwxr-xr-x. 2 root root 4096 Apr 28 2015 data40 drwxr-xr-x. 21 root root 4500 May 24 14:40 dev drwxr-xr-x. 135 root root 12288 May 24 17:55 etc drwxr-xr-x. 4 root root 4096 Apr 28 2015 home drwxr-xr-x. 4 root root 4096 Jan 8 2014 homes dr-xr-xr-x. 13 root root 4096 Feb 18 03:19 lib dr-xr-xr-x. 11 root root 12288 Apr 14 06:02 lib64 drwx------. 2 root root 16384 Jan 7 2014 lost+found drwxr-xr-x. 2 root root 4096 May 24 11:00 media lrwxrwxrwx. 1 root root 12 Apr 22 2014 MIDAS -> /MIDAS@aidas drwxrwxr-x. 29 npg npgstaff 4096 May 3 23:47 MIDAS@aidas drwxr-xr-x. 22 root root 4096 Dec 12 12:10 MIDAS@aidas.121215 drwxr-xr-x. 28 root root 4096 Feb 24 2015 MIDAS@aidas.240215 drwxr-xr-x. 2 root root 0 May 24 11:00 misc drwxr-xr-x. 2 root root 4096 Jul 21 2011 mnt drwxr-xr-x. 2 root root 0 May 24 11:00 net drwxrwxrwx. 1 root root 4096 Apr 28 10:55 ntfs drwxr-xr-x. 4 root root 4096 Feb 27 2014 opt dr-xr-xr-x. 411 root root 0 May 24 10:58 proc dr-xr-x---. 28 root root 4096 May 24 18:01 root drwxr-xr-x. 2 root root 12288 Feb 18 03:19 sbin dr-xr-xr-x. 2 root root 4096 Feb 27 2014 scratch drwxr-xr-x. 7 root root 0 May 24 10:58 selinux drwxr-xr-x. 2 root root 4096 Jul 21 2011 srv drwxr-xr-x. 13 root root 0 May 24 10:58 sys lrwxrwxrwx. 1 root root 16 May 24 18:02 TapeData -> /data10/TapeData drwxrwxrwt. 41 root root 65536 May 24 18:01 tmp drwxr-xr-x. 13 root root 4096 Jan 7 2014 usr drwxr-xr-x. 23 root root 4096 Jan 7 2014 var dr-xr-xr-x. 2 root root 4096 Feb 27 2014 WWW Encoding: HTML ELCode plain Suppress Email notification
