Description of problem:
A data mismatch is observed when comparing filesystem information reported by virtctl libvirt and guest OS.
Version-Release number of selected component (if applicable):
CNV: v4.21.0.rhel9-70
How reproducible:
100%
Steps to Reproduce:
1. create a fedora vm 2. check file system info 3.
Actual results:
filesystem total sizes reported by the CNV side, libvirt side, and the guest OS do not match.
Expected results:
all of total size should match
Additional info:
this issue just encounter for fedora, not fails for rhel/centos
Virtctl: {'name': 'vda4', 'mount': '/', 'fsType': 'btrfs', 'used': 696340480, 'total': 31673155584}
CNV: {'name': 'vda4', 'mount': '/', 'fsType': 'btrfs', 'used': 696340480, 'total': 31673155584}
Libvirt: {'name': 'vda4', 'mount': '/', 'fsType': 'btrfs', 'used': 697577472, 'total': 31673188352}
OS: {'name': 'vda4', 'mount': '/', 'fsType': 'btrfs', 'used': 625983488, 'total': 31672795136}
"Virtctl" - just an output of virtctl fslist
"CNV" - same as Virtctl but gets data directly from API
"Libvirt" - gathers same data as Virtclt from virt-launcher pod via virsh qemu-agent-command (virsh qemu-agent-command guest-get-fsinfo)
"OS" - gathers same data as Virtctl from guest os via parsing 'df -TB1 | grep /dev/vd'
