Subject: [PATCH proxmox{-backup,} 0/3] partially fix #6933: add option to specify zfs recordsize
Date: Tue,  4 Aug 2026 14:40:18 +0200	[thread overview]
Message-ID: <20260804124021.83704-1-s.shaji@proxmox.com> (raw)

The option to specify the `recordsize` was previously available neither
in the UI nor in the CLI. Users had to configure it manually using the
ZFS CLI. This series adds an option for specifying the `recordsize`
through both the UI and `proxmox-backup-manager` when creating storage.

Since adding support for editing this property at the dataset level
would require more changes, I am sending the creation related
changes first. Support for editing the property will be send
as a separate series.

I am also trying to benchmark with different `recordsize` and `volblocksize`
values on my host with an NVMe SSD. However, testing with multiple values
(1m,2m adnd 4m) are taking longer, and I am bit unsure how meaningful the
results would be because the test environment uses ZFS on top
of ZFS. Therefore, I am sending this series for an initial review.
The changes themselves are fairly straightforward.
