MapR installation is aborted due to the above error. when i checked for the error it shows that the disk is mounted to " / " (slash)
In the node verification step i dont see the disk (/dev/xvda1) got selected for installation
Sorry, but it looks like you're trying to mount MapR on an existing file system.
Did you select that disk or partition?
Hi Michael Segel,
Thanks for taking time to reply, for you're question "Did you select that disk or partition ?". No, i couldn't select the disk/partition because that option is disabled in there, but still Node verification step runs successfully (you can have a quick glance in previous attached image).
I tried creating new partition and give the same in Node Configuration but that fails in Node verification with an error (failed prerequisites with that new partition)
Here's some information on making sure disks are ready for use by MapR: Determine if a disk or partition is ready for use by MapR
Thanks for paying attention towards this issue, just like you suggested I've run the lsof <partition> command and found some processes are using the partition.But when i run fuser <partition> command there is no output again.
command there is no output again.
I checked for the error in disk-setup.0.log it shows that the disk is mounted to " / " (slash), i tried to unmount it but it turned out to be a failure
I've even tried creating new partition under (/dev/xvda) using fdisk /dev/xvda but it says ("To create more partitions, first replace a primary with an extended partition."), please guide me through this so that i could have a successful installation.
It will be useful to know more about your environment (version of MapR you are installing etc.). Also, reading Setting Up Disks for MapR
may be helpful.
It looks like this is a virtual server - /dev/xvda is typically the boot drive/Linux installation. Since this is a virtual server - rather than partitioning that drive, could you just add another one?
