Error

quotacheck: Something weird happened while scanning. Error 2133571361

Explanation:

Other day I was attempting to enable quota on one of my vms and I observed the quotachecl failed with above error.

This error most likely means that quotacheck was unable to perform read write operation on the disk where the provided partition was mounted.

Below errors are expected as seen for my case inside /var/log/messages
