New ZFSSA code release today

The first minor release of the 2011.1.1 major release for the ZFSSA came out yesterday.

You can get the code via MOS, under the "Patches and updates" tab. Just click the "Product or Family (advanced)" link, and then type "ZFS" in the search window and it really takes you right to it. Or search on it's patch ID, which is 13772123

Along with some other fixes, the most important piece of this update is the RPC flow control fix, which will greatly help those using the ZFSSA to backup an Exadata over Infiniband. 

If you're not already on the major release of 2011.1.1, I urge you to update to it as soon as you can. You can jump right to this new 2011.1.1.1 code, as long as you are already on 2010.Q3.2.1 or higher. You don't need to go to 2011.1.1 first, just jump to 2011.1.1.1.

If you are using your ZFSSA to backup an Exadata, I urge you to get on 2011.1.1.1 ASAP, even if it means staying late and scheduling special time to do it.

It's also important to note that if you have a much older ZFSSA (one of the 7x10 models that are using the older SAS1 HBAs, and not the SAS2 HBAs), that you do NOT upgrade to 2011.1 code. The latest code that supports your SAS1 systems is 2010Q3.4.2.

 **Update 2-26-12:  I noted a few folks saying the link was down, however that may have been a burp in the system, as I just went into MOS and was able to get 2011.1.1.1 just fine. So delete your cookies and try again. - Steve

Important - Clean your OS drives. Before you update your systems.

Some folks out there are not reading the readme file before they update, and are running into trouble. Remember the "Important Safety Tip" line in Ghostbusters about not crossing the streams? This is kind of like that.

Have you cleaned up your OS drives lately?

It's important. You should do this every now and then, but especially before you do a big update, such as the update to Q3.4 (which may have you running multiple updates, as explained in my previous post)

You want to remove system updates that are getting old. You may want to keep the previous system software in order to roll back, but do you really need the one before that and the one before that? Are you really going to roll back your 7000 to the system code you used in September 2010? I doubt it. Don't be a hoarder. Delete it. Call Dr. Drew if you need to.
Then, let's check your analytic datasets. These can get big before you know it. If you leave them running all the time, even when you don't need to collect data, you're asking for trouble. Either only run them when you need to collect data (you can do this manually or via a script or alert), or for goodness sake export them as a .CSV file at the end of each month and delete them off the system so they don't get too large. There have been issues reported of problems with the systems once these files got much too large. Part of those issues have been addressed in Q3.4, but you still need to keep it clean.

Very bad things will happen if you let your OS drives fill up. Think of all the atoms of your body moving away from each other at the speed of light. Furthermore, when you do an update, the update will go much more smoothly if you clean up the OS drives, first.
See the readme section below, which I'm sure you forgot to read...

The following section comes from the Q3.4 readme file:

1.4 System Disk Cleanup

Remove any old unused Analytics datasets especially any over 2G in size. The following command can be used to list the datasets.

node:> analytics datasets show
Datasets:

DATASET STATE INCORE ONDISK NAME
dataset-000 active 745K 2.19M arc.accesses[hit/miss]
dataset-001 active 316K 1.31G arc.l2_accesses[hit/miss]
dataset-002 active 238K 428K arc.l2_size
dataset-003 active 238K 428K arc.size
dataset-004 active 1.05M 2.80M arc.size[component]
dataset-005 active 238K 428K cpu.utilization

Also remove old support bundles or old software updates. It's important that the system disk has at least 20 to 25 percent free space. The following commands can be used to compare the amount of free space to the system disk size. In this case, 289G free / 466G size = 0.62 or 62% free space, which is reasonable. If you have trouble getting enough system disk free space call Oracle Support.

node:> maintenance system disks show
