The calculation whether to resize the partition only works with disks
with 512 byte sector size. Use values provided by sfdisk exclusively to
make sure comparing the same sector size.
Furthermore, it seems that sgdisk does not like sfdisk's backup GPT
placement:
$ sgdisk -e /dev/zram1
Warning! Secondary partition table overlaps the last partition by 250 blocks!
Today it seems sfdisk can handle GPT quite well. Use sfdisk for all
operations in hassos-expand.
The e2scrub utilities only make sense on system which use LVM. They
come with e2fsprogs and can't be disabled currently. Drop them manually
in our post-build script.
systemd-udevd substitutes variables starting with $ in the PROGRAM
argument. If a shell variable is to be used, two $ need to be used to
escape properly. This fixes three instances of the following warning:
Invalid value "..." for PROGRAM (char 58: invalid substitution type), ignoring, but please fix it.
The supervisor container requires the "hassio-supervisor" AppArmor
profile. Make sure our AppArmor service hassos-apparmor is a dependency
of the hassos-supervisor.service.
* Use systemd-growfs instead of resize2fs (#1106)
Since systemd 236 systemd has a built-in file system growing mechanism.
The mechanism relies on the kernels online file system resize
capabilities instead of the external resize2fs utility. Online resizing
is supposedly much faster since the kernel takes care of things.
This also makes sure that external file systems get resized which
previously have not been taken care of.
* Drop HA OS specific file system resizing
Since we have systemd-growfs in place now we can drop our file system
resizing code.
* Make sure /dev/disk/by-label/hassos-data is present after resizing
Note: systemd will retry mnt-data.mount later, so at least in theory
this shouldn't really matter. However, the journal has a lot of churn
due to that reordering.
It seems that page table mappings for compressed tables cause issues in
certain situation leading to "zram: Decompression failed!" errors.
Upstream Linux seems to have recognized the problem and a patch to drop
the functionality entirly has been proposed:
https://lore.kernel.org/linux-mm/20201117135632.GA27763@infradead.org/
* Enable hidraw driver (#1120)
The hidraw driver is required by some IoT devices such as Wyze sense or
Jablotron JA-100. Enable the driver on all platforms by default.
It seems that on certain setups the default DNS over TLS mode
"opportunistic" causes delays of ~10s when trying to resolve names. This
is probably caused by providers and/or firewall setups not properly rejecting
connections on port 853.
It seems that also other distributions (such as Arch Linux) still
disable DNS over TLS currently. Side step issues with DNS over TLS by
disabling it for now.
Directing people from discord to this page but there wasn't any mention they will likely be needing quirks enabled for usb boot on Rpi4. Also some minor layout adjustments on that section.
The EEPROM upgrade 2020-10-28 causes issues with JMS583 or JMS580
controller from Jmicron. Others reported that the same update fixes
reboot issues. Currently there is no Raspberry Pi 4 firmware which works
for all cases. Therefor don't ship an EEPROM upgrade so users can flash
and continue using what works for their setup.
Old Laptops are a popular choice to run Home Assistant: They have low
power consumption, are relatively fast and cheap to come by. However,
closing their lid by default puts a Linux system into suspend. This is
not what the typical user of Home Assistant OS wants. Ignore lid
activity in any state by default.
* Add Realtek RTL8812AU out-of-tree driver
This adds support for Realtek RTL8812AU devices such as the Hardkernel
WiFi Module 5A (with the RTL8811AU chipset, supported by this driver as
well). This patch uses Realtek driver 5.9.3.2 which has been made to
compile up to Linux 5.10.
Note: This driver does not seem to support 5GHz networks! But it seems
the only driver which supports the RTL8811AU chipset and also works with
recent mainline drivers...
* Enable RTL8812AU driver for Hardkernel modules
The WiFi Module 5A comes with a RTL8811AU chipset. Enable the driver for
all Hardkernel modules.
When we write the update to the boot partiton, there is nothing which
makes sure that data is written to disk. This leaves a rather large
window (probably around 30s) where a machine reset/poweroff can lead
to a corrupted boot partition. Use the sync mount option to minimize the
corruption window.
Note that sync is not ideal for flash drives normally. But since we
write very little and typically only on OS update to the boot partition,
this shouldn't be a problem.
After increasing the actual disk image size the capacity field in the
OVF description file still was mentioning 6GB. This seems to be
problematic for VMware hypervisor. Increase the size to 32GB as well.
* Revert "Fix boot from 128GB Micron eMMC on ODROID-N2(+) (#1064)"
This reverts commit 162084082e92384d40c1789457eb574f8790ea87.
This patches seem to cause issue on a ODROID-N2 with 32GB eMMC.
* Cap eMMC frequency to 24MHz in U-Boot for ODROID-N2(+)
Also remove the ODROID-C4 specific patch.
* Avoid waiting for external drive unnecessarily
Even though the condition to start hassos-data.service is not met (the
file /mnt/overlay/data-move is not there by default), it seems that
systemd waits for the dependencies for hassos-data.service. Don't
Require or Wants any dependencies which might not be present by
default.
* Use systemd to wait for partition using partlabel device
* Use sfdisk which allows to wipe filesystem signatures
Even though we zap the partition table using sgdisk, the file system
superblock (which contains the file system label) does survive. This
can cause problems when trying to reuse a disk previously already
labeled using hassos-data: It might take precendence on next boot
over the existing data partition on the eMMC.
Make sure to clean all file system signatures using sfdisk.
VMware as well as Qemu emulate LSI53C1030 SCSI controller when choosing
a SCSI controller has host interface for disks. For VMware this seems
to be the default choice. Enable the driver by default.
* Make the datactl command more robust
Validate target disk (partition) size to avoid a copy attempt which will
fail. If e2image operation fails, make sure the leftover copy is not
regonized as data partition.
* Fix hassos-data service device unit dependencies
In case the data partition is missing avoid using the Docker command.
The Docker command triggers a socket activation, which in turn makes
systemd wait for the data partition. This blocks entry into the shell
forever.
Just enter the shell in case data partition is not mounted.
* Rewrite datactl command
Prepare the target partition as part of the datactl command. Rely on
partlabel for the target disk since we are always using GPT on the
target disk. Use systemd and partlabel mechanism to wait and find
the target data disk. Keep using the file system label to identify
the source disk.
Also use e2image instead of raw dd to move data. This should
speed up the processes significantly.
* Fix corner case when reusing same disk again
* Add find utility helpful to find things
* Add hwclock utility useful to debug RTC issues
* Remove several utilities which are provided by util-linux (such as
dmesg, mount, blkid etc.)
* Drop unused utilities e.g. for raw nand (nandread/write/ubi)
