Re: [galaxy-dev] Galaxy Cloudman - How to analyse 1TB data ?
Hi Enis 1. I first created the LVM on 2 new volumes. 2. Mounted the LVM 3. I stopped all services (SGE, PostgreSQL, Galaxy). 4. Copied all data on filesystem /mnt/galaxyData to the LVM 5. Umounted /mnt/galaxyData 6. Mounted LVM to /mnt/galaxyData 7. Started all services As I mentioned in my previous posts all seems to be ok but I received a WARNING:galaxy.datatypes.registry:Overriding conflicting datatype with extension 'coverage', using datatype from /mnt/galaxyData/tmp/tmpGx9fsi. while running the Groom tool. I didn`t know what to do at that time and started messing around removing tmp files, restarting SGE etc. I later received the same error on a newly created Galaxy Cloudman instance with normal (1TB size) galaxyData filesystem. Greg Von Kuster replied to me I had to remove a duplicate value in the datatypes.conf.xml file. Hello Yves, You have one or more entries in your datatypes_conf.xml file for a datatype named coverage These should be eliminated from your datatypes.conf.xml file because they are not valid datatypes (unless you have added proprietary datatypes to your Galaxy instance with this extension). They were originally in the datatypes.conf.xml.sample file for datatype indexers\, but datatype indexers have been eliminated from the Galaxy framework because datatype converters do the same thing. Greg Von Kuster Currently I am running multiple Galaxy Cloudman instances to circumvent the 1 TB limit. If I find some time I will redo the exercise with the LVM.

Hi Yves, When you create the LVM file system - are you composing it from the volume that already contains the data (i.e., directory structure++ created by CloudMan) and then adding another volume into the LVM or starting with 2 new, clean volumes? Maybe trying again and not messing with SGE at all would at least resolve the SGE issue. Namely, SGE is on the root file system so it should be fine as is. I'd suggest stopping Galaxy and PostgreSQL services (from the CloudMan Admin), from the CLI, unmount galaxyData file system and proceed to create the LVM. Mount the file system and ensure the directories and the data that were there are still there. The start back PostgreSQL and Galaxy services. See if it all comes up fine and try adding a worker node if it does. Currently, CloudMan does not support composition of a file system from multiple volumes but I would think that as long as you did not restart the cluster and created the file system manually, things would work fine. I've been thinking about why you're seeing the described behavior and am not really sure so please let me know how the above process works out.

Re: [galaxy-dev] Galaxy Cloudman - How to analyse 1TB data ?
Yves; I am currently investigating if Galaxy Cloudman can help us in analyzing large NGS datasets. I was first impressed by the simple setup, the autoscaling and useability of Galaxy Cloudman but soon ran into the EBS limit of 1 TB L I thought to be clever and umounted the /mnt/galaxyData EBS volume, created a logical volume of 2 TB and remounted this volume to /mnt/galaxyData. How did you create this volume? I know there are some tricks to get around the 1Tb limit: http://alestic.com/2009/06/ec2-ebs-raid In the screenshot you sent it looks like Cloudman is a bit confused about the disk size. The Disk Status lists 1.2Tb out of 668Gb, which might be the source of your problems. All is green as you can see from the picture below but running a tool is not possible since Galaxy is not configured to work with logical volume I assume. Can you describe what errors you are seeing? It is truly a waste having this fine setup (autoscaling) but this is not useable if there is not enough storage ? Does anybody has experience with this ? Tips, tricks ... The more general answer is that folks do not normally use EBS this way since having large permanent EBS filesystems is expensive. S3 stores larger data, up to 50Tb, at a more reasonable price. S3 files are then copied to a transient EBS store, processed, and uploaded back to S3. This isn't as automated since it will be highly dependent on your workflow and what files you want to save, but might be worth exploring in general when using EC2.
