Log in to the ScaleIO node on which the get_info log collection in failing. In trace logs, LIA is unable to find any relevant files under the directory, though the getinfo file was created:

Cause

LIA code uses "Directory Entry" in order to locate the getInfoDump.tgz created as part of the collection. LIA uses a certain function called "readdir()" in order to get the content of the directory.

Once LIA calls "readdir()," it expects to get the field "d_type." This field indicates if "getInfoDump.tgz" is a regular file ("DT_REG"). Not all file systems support d_type

In cases where the file system created does not support "d_type," the returned value once the "readdir()" function call is: "DT_UNKNOWN" and LIA finds zero number of files in the directory.

If you have an XFS file system created, run the below command to check for the ftype=0:

Resolution

This is addressed in PowerFlex v3.6.

Workaround:
Ensure that the file system created where /tmp resides is Btrfs, ext2, ext3, and ext4.
For the XFS file system, ensure that the file system is created with "ftype=1"
