Title:
xfs freeze every week on multiple machines
Status in linux package in Ubuntu:
Confirmed
Bug description:
We run multiple machines that have the purpose of acting as a data
repository for Veeam backup. Each machine has 2x 256G XFS volumes that
use heavy reflinking. This works as intended, for one issue: our xfs
freeze once a week, a few minutes after midnight on Monday nights. We
can only do a reboot to get the servers working again. Then it works
for a week again.
We have been interacting with support from Veeam, but this looks like
some XFS kernel issue, or a race condition between the Veeam process
and XFS.
