Bug ID 681698: Using libtar fails with files larger than 2 GB - impacts qkview

Last Modified: Nov 22, 2021

Affected Product(s):
BIG-IQ Platform(all modules)

Known Affected Versions:

Opened: Sep 05, 2017

Severity: 3-Major


When you use programs, such as qkview for iHealth, BIG-IQ creates a .tar (tarball) file using libtar. If any of the files collected is greater than 2 GB, /bin/tar cannot read the output tar file and you will be unable to submit a qkview file to iHealth for analysis.


You will be unable to submit a qkview to iHealth for analysis. Other applications using libtar will produce invalid tar files.


The file collected using libtar (through qkview or other program dynamically linking with /usr/lib/libtar-1.2.11) is greater than 2 GB.


To work around this issue, you can extract the qview tarball with /use/bin/libtar. The oversized file will be a zero-length file. Alternatively, remove the file greater than 2 GB prior to running qkview or another program that uses libtar.
