  • Attempted to start copy of files from Caesar to Brutus, but we had an issue with the partitions on Brutus.
    • /home had 3 TB of data and we tried to resize that to 50GB, so we could use the rest of that space for /mnt/main
    • We were successful in resizing /home on Brutus to 50 GB, but we couldn't find a way to see unallocated space on the server to create a new partition. (documentation will be on systems group page)
    • We spent about 3 hours trying to fix this issue and start the copy process, but we were unable to complete the task today.

  • Run user scripts on Brutus
  • Compare train results
  • Mount drone servers to Brutus when we switch Brutus in for Caesar.


03/03/2015 (documentation)

Steps to setup /mnt/main on Brutus:

- vgs command to see free space available in volume group

1. lvcreate -L 1.5T -n lv_main vg_brutus (creates logical volume: lv_main in volume group: brutus) (should've used 3.52T) - Decided to go with a lower amount in case space was needed for other drives and it is easier to add space later than it is to reduce it.

(lvs - displays logical volumes)

2. Edit fstab - add mount point /mnt/main (fstab is config file that allows you to create mount points)

/dev/mapper/vg_brutus-lv_main /mnt/main ext4 defaults 1 2 (this is the line added to fstab so /mnt/main boots up with server and is configured)

3. mkfs.ext4 /dev/mapper/vg_brutus-lv_main (creates file system ext4 is commonly used)

4. mount -a (mounts /mnt/main)


  • Re-sized /mnt/main partition and file system from 1.5T to 3.52T
    • umount /mnt/main
    • lvextend -l +2.2T /dev/mapper/brutus_lvm-main
    • resize2fs /dev/mapper/brutus_lvm-main
    • mount /mnt/main
    • vgs and lvs commands to display volume group and logical volumes
  • Verified that there was no data loss on Brutus after the re-size of the partition and file system.
  • Starting verification of files in Exp directory for Brutus and Caesar


  • Verified files on Brutus by comparing directories on Brutus and Caesar using ls -all.
  • Read logs about running train experiments.


  • Updated systems group wiki page with information about how the logical volumes were created and resized on brutus.
  • Verified file permissions between Brutus and Caesar, will add documentation on wiki page.
  • Read more about running trains.


  • Didn't have enough time / ran into issues so we were untable to finish switch over of Caesar to Brutus, need to talk with group on setting up a better timeline with task breakdown.

Week Ending March 24, 2015

  • Attempt to run an experiment.
  • Discuss with Bruins group the objectives of our group for the remaining semester.



  • Read logs on running experiments, attempted to start a train, but Caesar server is down. Trying to work with the systems group members to find what the problem is, maybe related to the school move.
  • Talked with Bruins group by email over the break about what our team is planning to do.


  • Caesar server is still down and I haven't heard back from the other systems group members. I am assuming this is related to the school moving this week. I am unable to get to school this week to check on the server and the school is closed anyways because of the move.
  • Read logs about train experiments


  • Read logs about train experiments
  • Found out from systems group members that Caesar is running, but we are unable to access it due to a network issue.
