When deleting an Isilon folder, you might come across some peculiar behavior. When browsing with a file explorer to an SMB share and deleting a folder, the operation apparently succeeds and the folder disappears. When refreshing the share however, the folder is back. Resorting to an SSH session to delete the folder, you get an Operation not permitted error and the rm/rmdir command fails.
Did you ever install an Isilon cluster, connect all the cables and run through the configuration wizard, only to find out you still can’t connect to the cluster? Sure you did, happens to everyone. Maybe the cluster only has one 10GigE port online while the network team is still scrambling for 10GigE modules. Or maybe you have configured the invalid VLAN tag on the subnet. This post will group some of the more useful Isilon network commands, so you can enable VLAN tagging or add additional ports to the pool via the CLI.
Isilon scale-out NAS systems lean heavily on DNS. DNS plays a vital role in the way the clients access the files on the Isilon cluster: clients are distributed across nodes and network interfaces based on what your DNS reports back to the clients. This is all done by the SmartConnect component in the Isilon which is configurable up to a certain extent. In this post I’ll explain what SmartConnect does and will also share a tip to speed up your Isilon DR procedure.
Last year EMC installed two new three-node Isilon clusters for one of our customers. 13 months later the customer needs more capacity so the time for adding Isilon nodes to the existing clusters has finally come. Good news for me: since the initial install I got certified to install Isilon systems myself so these expansions are all mine! EMC marketing promises an Isilon cluster expansion in 60 seconds; let’s put it to the test!
“Check your email ;)”. That was the first Twitter DM I read one sleepy morning in June. It’ll suffice to say, a minute later I was wide awake: I was chosen to represent the EMC Elect at the EMC “Redefine Possible” MegaLaunch event in London (UK)! I knew about these launch events because my colleague Rob attended one last year in Milan. Excitement started building and a couple of hours later I figured out I wasn’t going alone…
