Schuster Lab Server Information

The Schuster Lab has three main file servers: linne, s2, and s3

linne

linne is a file server as well as the head node for the linne cluster (31 nodes running MacOS X 10.4, 5 nodes running Red Hat Enterprise Linux 4.5). linne maintains it's own user accounts, separate from the standard bx user accounts. To make it easier to share data, the uids of linne accounts have, for the most part, been synchronized so that they are the same as the uids of the corresponding bx accounts.

Sun Grid Engine

linne uses the Sun Grid Engine 6.0u6 batch-queuing system to manage jobs submitted to the linne cluster.

BioTeam iNquiry

linne also runs BioTeam's iNquiry Bioinformatics Portal which can be accessed here.

s2

s2 is a file server that is connected to both the persephone (s2.persephone.bx.psu.edu) and linne (s2.linne.bx.psu.edu) network switches. Each Dell PowerVault MD1000 uses 14 drives in a RAID 5 set with 1 drive as a hot spare to present a single virtual drive to the operating system. Each virtual drive is used to create a ZFS zpool. Each zpool contains two zfs file systems.

s2 runs samba and makes three locations available to illumina-ga: 

s2.persephone\\illumina-4 is on s2:/zfs/md1k-4/data/illumina
s2.persephone\\illumina-5 is on s2:/zfs/md1k-5/data/illumina
s2.persephone\\illumina-5 is on s2:/zfs/md1k-6/data/illumina
  • md1k-6
    • md1k-6/archive
      • used for archiving sequencing runs
      • exported read-only
      • gzip compression
    • md1k-6/data
      • used for arbitrary data
      • exported read-write
      • lzjb compression
  • md1k-5
    • md1k-5/archive
    • md1k-5/data
  • md1k-4
    • md1k-4/archive
    • md1k-4/data

Each zpool is auto-scrubbed once a week. A cron job runs the /root/monitor/check_server_status shell script once an hour and emails and errors to email addresses in the /root/monitor/error_log_recipients.txt file.
