But, I think that my question below was very generalist.5) Type fdisk -l 6) If you don't see any partitions, then go to step 7a. 7a) Create some dummy partitions using fdisk and save the partition table. 7b) Try to mount /dev/sda1 to /tmp/sda1 and see if there is .rocks-release file. You should be able to reinstall the node following this procedure.I don't have a good logical explanation of why I had to do it this way, but, at the moment, this is the only procedure that's working for me consistently.Srihari On 9/13/07, Somsak Sriprayoonsakul Thank you, Greg.Also, for the benefit of whoever else may try this: - /install/...However, when the installer gets to the point of creating the partitions, it shows the error message "An error has occurred - no valid devices found on which to create the file systems.." On a few nodes, it seemed like it created the partitions OK, but, when it goes to create the file systems, it shows this message.I tried various things at that point, like deleting the previous partition table on the disk and PXE booting again, deleting the hardware RAID volume on the drive and recreating it, removing the node from the cluster and doing insert-ethers as a brand new node, etc., but nothing worked.Name: output Type: application/octet-stream Size: 1631 bytes Desc: not available Url : https://edu/pipermail/npaci-rocks-discussion/attachments/20070913/87c72159/-------------- next part -------------- On Sep 13, 2007, at PM, Greg Bruno wrote: From robparrott at Thu Sep 13 2007 From: robparrott at (Robert Parrott) Date: Thu, -0400 Subject: [Rocks-Discuss] Kickstart install flumoxed by 2nd if on compute node In-Reply-To: Looking at the values from the database, it seems that that change is not in the database: This begs the question: How do I add the "ksdevice=eth0" to the default kernel arguments when installing a new host?thanks, rob On 9/13/07, Robert Parrott tags in an file have access to the front-end exported home directory (e.g. Thanks, Ion From greg.bruno at Thu Sep 13 2007 From: greg.bruno at (Greg Bruno) Date: Thu, -0700 Subject: [Rocks-Discuss] Kickstart install flumoxed by 2nd if on compute node In-Reply-To: installing a new host?So, after trying several different things, I think I finally found a consistent way to reinstall nodes (bypassing that "no valid devices found.." error). First, I deleted the node from the Rocks database: insert-ethers --cabinet=1 --rank=0 The node PXE-boots, starts kickstarting, and throws the stupid error message again.Assume that you have screwed up the node to the point where you cannot boot it from the local hard drive anymore (that was my situation here anyway because one of my attempts was to wipe everything out from the hard drive and reinstall from scratch, but, yet, that didn't work! At this point, I switched to virtual console #2 on the node. fdisk /dev/sda [created /dev/sda1 with 100MB] [created /dev/sda2 with 16GB for swap] [created /dev/sda3 with 20GB for / ] [created /dev/sda4 with the rest ] Saved the partition table, but, didn't create any file systems on it.
