Source: linux Version: 6.12.57-1 Severity: normal The setup we have on openqa.debian.net and it's openqa-worker machines is that the workers have a read-only NFS mount of a share containing the .iso images that are used for booting the test VMs.
All kernels that I have available since 6.12.48 (6.12.57 6.12.69 6.12.73 & 6.18.5) cause the workers to fail when they try to apply a "consistent read" lock, giving the error message: No locks available One can demonstrate that by running this on the NFS client: $ flock -e -w 4 /var/lib/openqa/factory/iso/xfce_sid_20260223T140607Z.iso sleep 1 flock: /var/lib/openqa/factory/iso/xfce_sid_20260223T140607Z.iso: No locks available meanwhile, running that flock on the server works fine. BTW Here are the journals from booting various versions of the kernel: https://hands.com/~phil/tmp/openqa-nfs-lock-issue/ Cheers, Phil.
