Subject: [pbs-devel] [PATCH proxmox-backup 0/2] raise nofile limit for GC on S3 stores
Date: Tue, 18 Nov 2025 11:45:27 +0100 [thread overview]
Message-ID: <20251118104529.254348-1-c.ebner@proxmox.com> (raw)
Datastores backed by s3 object stores rely on per-chunk file locks
for consistency. However, the soft limit for open file handles might
be to low during garbage collection, as there chunks are processed in
batches of up to 1000 objects. Therefore, use the pre-existing helper
defined in the proxmox-backup-client to raise the resource limits to
the hard limit at start of garbage collection for s3 backed
datastores.
