Thanks.
this is an issue with certain shared-storage operations in PVE - they have to happen under a pmxcfs-lock, which has a hard timeout. if the operation takes too long, the lock will run into the timeout, and the operation fail. there has been some recent development to improve the situation: https://lists.proxmox.com/pipermail/pve-devel/2021-September/049879.html but it hasn't been finalized yet. _______________________________________________ pve-user mailing list [email protected] https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user
