Subject: [pve-devel] [PATCH docs] installation: document advanced btrfs options
Date: Tue, 12 Nov 2024 15:33:52 +0100 [thread overview]
Message-ID: <20241112143441.867474-1-c.heiss@proxmox.com> (raw)
Also includes the new `compress` option that has been recently
introduced in the installer.
Signed-off-by: Christoph Heiss <c.heiss@proxmox.com>
---
The `compress` option will only be included starting with the next (8.3)
ISO release, FWIW.
I can leave it out for later if preferred, but a newer pve-docs will
probably not bumped/hit the repos until the next release, I'd guess?

+Advanced BTRFS Configuration Options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+No swap space is created when BTRFS is used but you can reserve some
+unpartitioned space on the install disks for swap. You can either create a
+separate partition, BTRFS subvolume or a swapfile using the `btrfs filesystem
+mkswapfile` command.
+
+`compress`::
+
+Defines whether compression is enabled for the BTRFS subvolume. Different
+compression algorithms are supported: 'on' (equivalent to 'zlib'), 'zlib', 'lzo'
+and 'zstd'. Defaults to 'off'.
+
+`hdsize`::
+
+Defines the total hard disk size to be used. This is useful to save free space
+on the hard disk(s) for further partitioning (for example, to create a
+swap partition).
