Create an SMB/CIFS share on Ubuntu

file-sharing-folderSteps

  • Install samba

sudo apt-get update
sudo apt-get install samba

  • Set the samba password for the user account that will be used with the share

sudo smbpasswd -a userName

  • Keep in mind that the user must already exist or a Failed to add entry for user error message will be thrown.
  • Create a directory to mount the share

mkdir /mnt/smbShare

  • Add the share config to the bottom smb.conf file

sudo nano /etc/samba/smb.conf

[shareName]
path = /mnt/smbShare
available = yes
valid users = userName
read only = no
browseable = yes
public = yes
writeable = yes

  • Restart SMB

sudo service smbd restart

  • Test accessing the new share.
    • If accessing from a Windows box then the username needs be pre-fixed with the name of the server hosting the SMB share
      • i.e. UserName admin should be UbuntuServer\admin

Upgrade Drive Firmware on an Isilon Cluster

Info

Occasionally EMC will release new firmware packages for various drives used in Isilon nodes. The process documented here can be used to upgrade the firmware on the drives prior to OneFS version 7.1. The firmware upgrade process prior to OneFS version 7.1 uses the Isilon Drive firmware package.

Prep-Steps

  • Login to support.emc.com
    • PowerLink account required
  • Search for Isilon Drive Firmware Package
  • Download the latest package (1.9 as of 02/2015)
    • Review the release notes of this package
  • Copy this package onto the Isilon cluster
  • Determine how the firmware upgrade will be applied
    • Serial – This is the recommended method. This requires physical access to each node in the Isilon cluster
    • SSH – This allows the firmware upgrade to performed remotely. Unfortunately in some situations the firmware upgrade process can fail after SSH has been stopped on the node. In those situations the node will remain offline until a reboot is performed via a serial connection. Therefore SSH is not the recommended method.
      • If using SSH then the Infiniband IP address must be used as opposed to the 1Gbe or 10Gbe interface. The Infinband IP(s) for each node can be obtained via the Web GUI by simply clicking on the node number and looking for the IP next to int-a or int-b.

Upgrade Isilon OneFS

Info

This page documents the basic steps of upgrading the Isilon OneFS operating system. This specific upgrade was from 7.0.2.5 to 7.1.1.2 but the process and screenshots should be accurate for any 7.x upgrades.

Prep-Steps

  • If possible, perform a cluster reboot or reboot each of the nodes individually roughly 2 weeks prior to the OS upgrade
    • Skipping this step may cause the OneFS upgrade to fail on the last step.
  • Download the new version of OneFS from support.emc.com (PowerLink account reqd)
    • Click Downloads
    • Under Find a Product, type Isilon OneFS and hit enter
    • Browse to the desired version of OneFS on the left hand side
    • Expand the Full Release section
    • Download the package that ends in installation file
    • Place this installation file somewhere on the Isilon cluster that will be upgrade
  • If upgrading from 6.x -> 7.x or 7.1 -> 7.2  then a full cluster reboot will be required as opposed to a rolling upgrade.

Restore an SRX Firewall to a Rescue Config

Info

If the configuration of an SRX firewall is ever broken by committing a bad change then the firewall can be rolled back via the rescue config. This process requires that the rescue config was originally configured and also requires physical access to the firewall.

Prep Steps if the firewall is in a cluster

  • Push the power button on the secondary firewall
  • Wait 2-3 minutes until the secondary firewall has finished powering down
