Unable to access folders or run any scripts in my clemson cluster

[Chandrasekhar Syamala]

Hello Team,

I was working with cluster of 8 nodes in clemson and I was running some Python script over the HDFS.

However, since Saturday I was unable to access my folder data within the node 0, vm0 and also unable to run any scripts like start-dfs or stop-all as it throws the following error
 

/usr/bin/env: ‘bash’: Input/output error

With Regards

Something is wrong with the root filesystem. Some commands are failing,
others aren't. Could be that the ones that work are in the RAM cache and
the root filesystem is corrupted.

You can use the list view or the topology view of your experiment to put
the node into recovery mode. That will boot it into a RAM based MFS from
which you could run "e2fsck -nf /dev/sda" and see if it thinks the filesystem
is intact.

Yes, it seems the file system is corrupted.
What are the options I have here now? Can we somehow recover it?
