Build

The MegaRAID SAS controller uses the (4) 2TB drives in a RAID6, for an effective 4TB live storage with 2-drive redundancy.

The resulting disk space is partitioned thus:

Model: LSI MR9361-8i (scsi)
Disk /dev/sda: 4000GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End     Size    File system     Name  Flags
 1      1049kB  128GB   128GB   linux-swap(v1)  swap
 2      128GB   153GB   25.0GB  ext4            logs
 3      153GB   4000GB  3847GB  ext4            root  boot

Partition 2, named "logs", is mounted at /var/logs to prevent any issues down the road with overflowing logs.

Good documentation on the LSI MegaCli64 binary in /usr/sbin. This comes up because apparently the MR9361-8i occasionally has issues with things like automatically rebuilding an array after a drive is removed and replaced.

Filesystem

9bc4fdb4-a34a-4e17-bb81-fa1d9cb271bd is an 8GB SanDisk Cruzer Fit in a rear USB port, which is mounted at /boot to avoid the GRUB weirdness we have been enjoying for a year now.

Model: SanDisk Cruzer Fit (scsi)
Disk /dev/sdd: 8003MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number  Start   End     Size    Type     File system  Flags
 1      1049kB  8003MB  8002MB  primary  ext2         boot, lba

Services

  • Local fileserver over Samba
    • Type \\10.13.0.17\i3fileshare for access.
    • See HOWTO_Connect_to_i3fileshare for further instructions.
    • Please create your own directory and avoid messing with others'
    • This storage is NOT at this time backed up in any way; users are expected to have their own backup solutions for critical data
    • Regularly scanned with clamav; infected files are deleted.
  • apcupsd monitoring of big UPS
    • Shared on a standard apcupsd NIS on port 3551
  • Local BTSync shares for the I3DataVault

Power Use

Google Sheets

From Matt Gardeski: These are all estimates based on measurements of equivalent parts. If someone wants to do some actual measurements on the hardware we're running, please do. I think the MARS box and the HP have power monitoring built in to the server management hardware.

Notes

2016-03-19 mtfurlan Installed `apt-transport-https`, `vim-nox`, and `tmux`. The first because `apt-get update` failed, the others because they make my life easier.
