btrfs | WinBtrfs - an open-source btrfs driver for Windows | File Utils library

There steps may help you in getting resolved this issue

1. Reduce the number of gunicorn workers
2. Generally, it is recommended (2 x $num_cores) + 1 as the number of workers to start off with
3. And also Increase RAM from 512 MB to least 2GB (or 1 GB)

Not sure, but maybe you should update your BIOS first from Windows.

According to the btrfs wiki FAQ:

... the COW status can be modified only for empty or newly created files.

If you really need to change the COW status, I suppose you will need to copy your current files to new files.

Just do not put the extension .ko

I solved it! I created a bash script that syncs all snapshots with a date in the name to the remote server. The date is subtracted from btrfs subvolume show.

So daily.0 can become 2021-09-20-08-44-46 on the remote.

I sync backwards. daily.30 first. daily.0 last. This way I can pass the proper parent to btrfs send. E.g.: btrfs send -p daily.30 daily.29.

If the date named snapshot exists on the remote, I check with btrfs subvolume show whether it was properly synced. If not, I delete the remote subvolume/snapshot and re-sync. If it was already synced, I will skip the sync. A proper synced subvolume/snapshot has a Received UUID and readonly flag.

After syncing I compare all snapshot names of the remote to what was just synced. The difference will deleted (thus old snapshots).

I might share the code in the future when it's all been stable for a long run. For now I hope the above information will help others!

Problem reproduced, and resolved by replacing -ldflags="-extld=$CC" with -ldflags="-extld=aarch64-linux-gnu-gcc".

Alternatively, you can also export the CC variable beforehand.

The error output was caused by mismatching linker (with your original build command, it was still the x86-64 linker that got invoked).

Tested on two hosts of mine: one Ubuntu 20.04 + go1.13, the other Ubuntu 18.04 + go1.16.

More explanations:

Seems that the in-line CC env variable setting is passed to the go tool, but not used in the shell's parameter substitution. The following output (Bash 5.0) demonstrates this:

If sda2 and sda3 are the same size (low-level size, that is... not FS size... you can see that with say fdisk), then you can copy binary content of sda3 into sda2 with something as simple as:

First using virt_to_phys() is only supposed to be used with kernel lowmem(directly maped RAM region) region so you cant get physical address of a user space it's even not allowed even with kernel space regions like vmalloc. only allowed with lowmem region since it's at fixed offset of PAGE_OFFSET.

If I'm correct you try to write directly to physical memory and hope your result will be seen in user space app. If this is what you want there is no way to do that(at least an easy way).

The hack would be like: you will want to view the page tables of the app and record where will be this address be located in physical ram. on x86 page tables address is stored in CR3 register. The next problem is that the CPU is already set in protected mode with PG flag set in CR0 (ie; using paging) which make the MMU read the address as virtual and do the conversion itself to physical(you can't interfere). So to access physical memory you must switch to real mode with paging disabled(which must be if you are will be using real mode). This will probably means that you will have to call BIOS routines to do the hard work for you.

You can use
